"Dr Jekyll and his monstrous alter-ego join forces with his ex-fiancée to solve a series of disappearances across Victorian London in this thrilling mystery, perfect for readers of Stuart Turton and James Lovegrove.

When Muriel Carew attends a lavish society party, the last person she expects to bump into is her ex-fiancée Henry Jekyll, a man she's not seen for many years. When Jekyll turns out to be investigating a series of missing persons in London, Muriel is intrigued. But Jekyll is not working alone, and if Muriel wants to aid in the investigation, she must work with both Henry and his partner, the monstrous and uncouth Mr Hyde.

As their search takes a dark turn and a missing persons case becomes a murder investigation, Muriel finds herself deep in a mystery involving a nefarious group exploring their own hidden alter-egos within the beating heart of London's high society.

To solve the case and bring those responsible to justice, Muriel must find a way to place her trust in Mr Hyde, which might mean uncovering secrets about her own life she never dreamed of discovering."

I think Jekyll and Hyde would make a surprising effective duo solving crimes.

I received this book as an ARC from Titan Books and NetGalley. The story is told from the point of view of Muriel Carew, Henry Jekyll’s ex-fiancée. Muriel reconnects with Henry and embarks on an adventure, investigating a series of missing persons cases. Edward Hyde is present and is an extremely interesting figure in the tale. I thoroughly enjoyed the book, and I hope it is the first in a series. Highly recommend!!!
