Thank you to @SourceBooks and #NetGalley for the digital ARC. The opinions expressed here are entirely my own.
As a true crime fan, this book caught my eye because I had never heard of Tony Costa (I abandoned "The Babysitter: My Summers with a Serial Killer" by Liza Rodman). And I wasn't disappointed. Sherman shares the intriguing story of Costa, a charming hippie with loyal female followers who's battling his raging alter ego. Combined with the overlapping stories of Chappaquiddick, Kurt Vonnegut vs. Norman Mailer and the Manson murders (which overshadow Tony's crimes) and you've got a really great read about a turbulent time in the US.

Thank you to NetGalley and Sourcebooks for an advanced electronic copy of this book in exchange for an honest review!

Tony Costa - the serial killer on Cape Cod. True crime: dark and unforgiving.

Was the premise interesting? Yes. Were all of the sections about Tony Costa engaging? Absolutely. However, there were so many people discussed in the story without any obvious connection. It made sense to talk about some individuals who linked to the narrative, but others made me wonder why they were included at all. It may be a case of "it will all make sense later," but I found it frustrating because it felt like it was dragging as I read it.

The became interesting. It started out tedious and seemed to be about a feud between two writers. The novel had too many subplots going on. But eventually it got on track. Once that happened the book was interesting.

I had never heard anything about these events before going into this book so I can easily say that this was a wild ride from start to finish. If you listen to true crime podcasts this would be a good one for you.

Helltown by Casey Sherman, when I first learned of this, I was super excited, thought this was a true crime novel, however there was , it seemed to me, more fiction throughout. Still not sure how I feel about that. 3 stars, I feel like the author did well with gathering information and background for this, I just couldn't immerse myself into the fact and fiction aspect of this story. Thank You to Netgalley, and the author for the complementary ebook.

I received this book free of charge from NetGalley in exchange for my honest review.

Who knew there was another Manson like serial killer in the US in the late 60's. Not me! How did I not hear of this killer like we did of Manson?

The story started off kinda slow for me and I couldn't figure out why there was so much attention being given to Norman Mailer and Kurt Vonnegut. Like what do they have to do with a serial killer. I feel like a lot of that backstory could have gone away and not impacted the overall story. The last half of the story was much better.

Part of this are pretty hard to read and I had to take breaks so I didn't have nightmares. I can't imagine being on this jury.

While the subject was fascinating, the book was about 100 pages too long

This is a thick book, that a thin book was screaming to get out of.
The true crime portion of Tony Costa was FASCINATING! I had never heard of this serial killer and his gruesome crimes. I thought that the author did a great job of going over the details of how Tony lured the women to their deaths.

However, the parts with Norman Mailer and Kurt Vonnegut was quite unnecessary and I felt that the author really editorialized what the authors was thinking/feeling.
Further the Norman Mailer connection could have been completely removed from the book and it would have been just fine.

Another disappointing addition to the book was the addons....what I mean is that the author added on the moon landing, Mailers coverage of the moon landing, what Vonnegut thought of the moon landing, Ed Kennedy killing a lady, Charlie Manson....if something happened near the time of the Costa killings.....this author put it in.

I almost gave up on this book at the 15% mark, when the book got bogged down on the Norman Mailer/Kurt Vonnegut connection...in the end, I am glad that I stuck with it because I learned about Tony.

I wished that the author had updated the readers on if the District Attorney who prosecuted Tony, did he seek re-election?
Did "STrawberry Blonde" really kill the lady in the dunes? OR was that just made up?

Overall this book couldn't be called True Crime, nor could it be outright fiction.

I was intrigued by this unfamiliar true crime story, as Cape Cod is a favorite vacation spot, and I was curious about this dark period in its history. Unfortunately, the book was a difficult read with the horrifyingly gruesome details of the murders. Rather than narrative, these passages felt gratuitous and contrived in a way that was off-putting. I was expecting/hoping for more of an "I'll Be Gone in the Dark" type of treatment, but this was borderline torture porn. I did enjoy the intertwined historical context of the politically charged national climate and literary rivalry between Mailer and Vonnegut.

The writing turned me away from this one, unfortunately. I was hoping for something more in the vein of I'll Be Gone in the Dark, but this one felt too fictionalized. I wanted something more informative, but this is written as a suspenseful novel more than a nonfiction outing in true crime. I think I may try it again later with a different mindset (now having a better idea of what kind of book to expect); I think then I'll enjoy it more.

When I saw the blurb for Helltown, the account of a serial killer on Cape Cod in the 1960s, I was curious. I didn’t know anything about Tony Costa, and with the time period I was hoping for a interesting non-fiction read.

While the book does cover Tony Costa’s murders, it reads much more like a thriller novel than it does true crime…which honestly put me off. I love a good thriller as much as the next nerdy goth, but turning the actual murders of young women into something that felt more fictionalized wasn’t amazing.

The scope of the story the author tells widens and narrows, bringing in local authors, police and the convicted themself. It tries to bring all these disparate elements together in a good story, but falls short simply because of the breadth they were trying for.

I feel like there are two warring ideas here, the bold non-fiction account of murders, as well as the thriller that takes these murders and spins something new out of them. I wish we had gotten one or the other, instead of this which falls somewhere in between the two.

True Crime writer Casey Sherman’s latest book, Helltown: The Untold Story of Serial Murder on Cape Cod (Sourcebooks, 2022), is a fascinating and unflinching look at the crimes of Tony Costa and the two great American writers who were inspired by him.

Tony Costa’s crimes have been given less attention in the true crime genre than other infamous serial murderers, but as Sherman’s book demonstrates, Costa’s crimes are garnering more and more attention from writers in recent years. Following Liza Rodman’s true crime-memoir The Babysitter: My Summers with a Serial Killer (co-authored with Jennifer Jordan, 2021), which details Costa’s crimes and Rodman’s experiences with Costa himself as a child, Sherman’s book is a narrative account of Costa’s life, the murders he committed, and the social and political moment surrounding his offenses and eventual capture. Beginning in the late 1960s, during a time of enormous political upheaval due to the Vietnam War, Sherman’s book recounts Costa’s life in Provincetown, Massachusetts. Although Costa at first appears to be simply a recognizable member of the hippie scene in Ptown as a drug dealer and a sometimes-informant for the local police, when women begin to disappear without explanation, Costa begins to look more and more like the odd man out to locals and law enforcement alike. Eventually, when the bodies of four women are discovered in an isolated stretch of woods, Costa becomes the prime suspect in a series of brutal killings, the details of which are almost too gruesome to believe.

Meanwhile, Sherman’s narrative moves away from Costa and his crimes to recount the literary and social details of the lives of famous American novelists Kurt Vonnegut Jr. and Norman Mailer. Rivals who were known to each other in the small world of American letters, Vonnegut and Mailer both became interested in the Costa case as writers and intellectuals of the period. Sherman’s book delves into the literary history surrounding the lives of Mailer, Vonnegut, and their interest in Costa, adding a highly original and interesting twist to this work of narrative true crime.

Sherman chooses to recount the narrative of Costa and the US in the 1960s and 70s using many of the hallmarks of fiction writing. Sherman adapts dialogue, plot, and characters around a very real case, making this text read more like a novel than like a work of nonfiction. This style is very effective, and allows for the multiple threads of the story to interconnect at a pace that makes sense for the whole of the book. While the dialogue at times reads as more stilted than any actual speech might be, Sherman’s writing has the sharp, sparse quality of good and clear narrative.

Helltown’s narrative structure, however, does not detract from the extensive research involved in writing a text like this one. The text is obviously grounded in the news media, trial transcripts, and autopsy reports from the period, and Sherman leaves no stone unturned in his examination of the Costa case. Sherman pulls no punches in recounting Costa’s brutal crimes, fully unpacking just how tragic and heinous the murders were and underscoring the victims’ family’s immense loss.

Overall, Helltown is a must-read true crime text for those interested in literary history and serial killer cases from this pivotal period in American history.

Helltown was brilliantly researched and compiled by Casey Sherman. However at times I felt like there was just too much going on. We had a serial killer, Kurt Vonnegut, social issues in that current time, and other issues being discussed all in the same book. When we were learning about Tony Costa and his psychotic ways I loved the book, being a true crime aficionado and learning about someone I had never heard about. However, it just because a little jumbled throughout and not being able to follow at certain times.

For a fan of True Crime I fell in love with this one from page 1. Knowing that I have yet another serial killer to do research on is super interesting. I used to think I knew about most serial killers but this one was a new one for me. The way Sherman writes this is also very interesting and entertaining. It was an easy read unlike some non fiction books I read! I truly think most true crime lovers will love this book. So go and grab it!

An interesting approach to the true crime genre, Helltown narrates the events of Cape Cod serial killer Tony Costa. The crimes were committed in 1969 and Sherman does a fantastic job of providing the reader with the context and setting of the times. We get the political climate (Vietnam, Kennedys, assassinations), the drug culture, the music, and the ubiquitous hippie scene. Time and place is conveyed in rich, heavily footnoted detail. Interwoven throughout are the competing narratives of Cape Cod authors Norman Mailer and Kurt Vonnegut as they're both interested, for reasons of their own, in telling Tony Costa's story. Sherman even makes a call back to Capote's classic In Cold Blood. Helltown is very meta.

Sherman's approach almost undoes the meticulously researched "true" part of his true crime novel. There are numerous footnotes throughout the chapters, referencing newspaper articles, trial transcripts, the killer's own unpublished work, the biographies of both Mailer and Vonnegut, other novels about the killings. Tons of footnotes. The glaring absence of footnotes in some chapters call way too much attention to the invented side of this book - some chapters and scenes are pretty much 100% fiction, And some of these depictions are wild.

Those imagined, fictitious parts didn't work, pulling me out of the actual narrative and timeline. There seemed to be fewer references and footnotes as the book progressed. Perhaps Sherman thought they beefed up sections. Some were pretty lurid, on par with the actual crimes. They felt superfluous. In the author's note Sherman states that he was trying something new in this genre by combining both fact and fiction. This book was strong enough to stand on its own without the made up padding, hence the neutral rating.

My thanks to NetGalley and Sourcebooks for the ARC in exchange for my review.

I had never heard of Antone Costa and his crimes before reading this book. The true crime portion of this book was super interesting, I just wish the author hadn’t taken quite so many liberties. It was hard to tell what was fact and what was fiction. I also wasn’t a huge fan of the Vonnegut/Mailer drama. I think that a lot of it could have been cut out without losing the plot of the book. That being said, the story of Tony Costa was so compelling and disturbing. The parts of the book that focused on Costa and his crimes were great!

This book was so good and kept sucking me in! So well written and great for true crime fans! Thank you for the arc!

I really enjoyed this true crime novel about Cape Cod and the pervasive drug culture of the late 60s. I appreciated that the author was able to put this crime into context for the readers, including details of the literary culture, Chappaquiddick, the Space Race, the Manson murders, all of which were part of the fear and tension surrounding these murders. However, there were lengthy detours into the lives of Vonnegut and Mailer that felt like they held the narrative back. I also didn't love some of the more fictionalized aspects including the hypotheticals about what happened to the Girl of the Dunes, a victim of a similar murder but one that happened after Tony Costa killed himself in prison.

I am not intimidated by long books because it usually means there's a great story within all those pages. This book, however, was just WAY too long. I'd say it was about 200 pages too long.

I was intrigued with the idea of this book. A serial killer in Cape Cod? Yes! Cape Cod screams safe and peaceful, so the idea of a killer going around and killing young women was a little appealing.

However, there was just so much extra in this book. Extra people, extra events... It was just too much.

For example, there was quite a lot of detail about the Apollo 11 lunar landing, the Chappaquiddick/Ted Kennedy incident, and the Manson Murders. I understand the reference to these events. It was to let us know about the times and to connect the Cape Cod murders to other significant events in history. But a simple reference would work. I didn't need paragraphs of detail.

Along with the detailed events, there are also quite a few additional people in the book too, such as a couple of local authors, a woman who understands the severity of witchcraft, the DA, and a so called witch as well. It started with the introduction of the two authors and the rivalry they seemed to have with one another. The whole time I read those paragraphs, I kept wondering, "What does this have to do with the bigger picture?" Yes, they all had little connections to the story and the case, but again, a simple reference or two would have been sufficient.

Overall, I give this book three stars. At times, I felt like I was reading a horrible fiction story. They was the thoughts of many of the people were presented made me really think it was more of a work of fiction.

Thank you to NetGalley and Sourcebooks for the advanced copy in exchange for my honest review.

DNF-ed this book. Beginning was just too slow and too sluggish to capture my attention, as well as the fact that the first few chapters kind of read like a collection of Wikipedia pages. Well-written Wikipedia pages, mind you, but Wikipedia pages nonetheless.

As a fan of true crime, I looked forward to reading this book about a serial killer that I'd never known about. Sherman seems to have done a lot of research for this book and gives detail to both the killer, Tony Costa, and the victims. When I choose to read the "untold story" of a serial killer that is billed as non-fiction I kind of expect the story to be true and mainly about that primary subject, but this is where my problem arose. The book is filled with dialog and narrative that the author admits in the Author Note at the end were moved around or reimagined. There are also entire chapters devoted to the authors Norman Mailer and Kurt Vonnegut, writers from the area of the crime and whom the author mentions influenced his own writing. Unfortunately, these chapters detracted from the story of Costa and his crimes for me. I truly wish that I'd liked this book more, but thank Sourcebooks and NetGalley for the early read.
