“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?
