"Another compelling entry in this complex, suspenseful series." --Booklist (starred review)

In the third volume of the bestselling Frieda Klein Mystery series, the brilliant but troubled London psychotherapist returns--only to journey into a darkness from which there may be no return.

Ruth Lennox, mother of three, is found dead in a pool of her own blood. Detective Chief Inspector Karlsson calls Frieda, hoping she can offer a new angle. But when it emerges that Ruth was leading a secret life, her family closes ranks. Still reeling from a recent attempt on her life, Frieda starts down a dangerous path that seems to lead to a serial killer who has long escaped detection. Is she getting closer to unraveling either case? Or is Frieda just the victim of her own paranoid, fragile mind?
