In his excellent introduction to the American Mystery Classics reprint, Joe. R. Lansdale recommends that readers attempt to consume this in a single sitting. The reason is that this is written as one long manuscript without any chapter breaks, almost as a stream of consciousness, and by doing so you allow the narrative to slowly build upon your senses of apprehension and dread.

I opted to follow Lansdale's advice and I would strongly recommend that you do as well. This book is one of the trippiest and most disconcerting I have read in a while and I agree that it rewards a reader's undivided attention.

The book is told from the perspective of Dr. Henry Riddle, a young surgeon who is attempting to make sense of a bizarre series of events. These concern Elinor and Inis - a couple who were travelling through Vermont from out-of-state in a plan to elope together and the hitchhiker with a torn ear, sharp teeth and a strange corkscrew walking style that joined them on their journey.

The particular part of Vermont they are in happens to be very remote and Riddle himself is a visitor, having been called into the area to provide care to a gravely ill man. The party decides to stop at the nearby Dead Bridesgroom's Pond for a picnic but the meal has a violent end as the hitchhiker apparently kills Inis and attempts to murder his fiancée before speeding away in a car containing the corpse.

Dr. Riddle tries to understand is why he did not pass that car when it was seen heading along the road he was stranded on and given there was no turning before it should have passed him. It is a perplexing situation that becomes even stranger when he learns that the man he witnessed walk past him in the forest had been killed a short time earlier when he was struck by the fleeing car.

Rogers writes in a seemingly unfocused style, jumping forwards and backwards in the order of events. This represents his stream of consciousness and also his sense of confusion as he works around different points in the series of events, trying to make some sense of those experiences. The experience is as disorienting for the reader as it is for Riddle and the more we learn, the more confusing those events appear.

This unorthodox storytelling style is one of the most memorable aspects of the book because it is no mere gimmick. The apparent disorder of Riddle's thoughts helps establish the mood and tone of the piece while also reflecting a key theme of the novel - that our observations may be unreliable as things are not always as they appear.

That idea can be applied to the novel itself as much as its plot. On the surface this appears to be a psychological suspense story with countryside noir elements. Those aspects of the novel are certainly there but beneath them Rogers has crafted an exceptional example of a fair play mystery with clever, logical clues and an audacious solution that you have a reasonable chance of reaching for yourself. It is a remarkable achievement that makes me wish Rogers had been more prolific in the genre.

The plot, themes and tone would be reason enough to read this but they are not the novel's only strengths. I was struck by Rogers' depiction of the rural setting and the feeling of being really isolated. This is not only important to the plot, it feeds into the book's strange sense of atmosphere as we are reminded that you could travel for miles without seeing anyone and that if a killer does still lurk nearby, the characters have little hope of getting help.

This atmosphere seems to thicken the more you read and a slow, inexorable sense of dread grows as the tale nears its conclusion. That ending is as thrilling as it is clever, the tension building right up to the end.

There is plenty more I could say about this book but unfortunately doing so would spoil the book's surprises. Instead let me sum up by saying that I found this book to be a truly gripping and unpredictable read. I appreciated the clever blend of psychological suspense and fair play mystery with several apparent impossibilities and that wonderful sense of atmosphere Rogers creates.

Highly recommended.
