I found The Patient’s Secret by SA Falk an interesting and entertaining read.

The plot kept me engaged, moving along at a pace that kept me turning pages, and the twisty ending left me feeling satisfied. Dr Sharon Stevenson is a forensic psychiatrist engaged to assess whether an arrested suspect/the patient is mentally fit to stand trial. The patient presents a case of Dissociative Disorder with four distinct personalities, which had me scratching my head a bit as I tried to keep track of them. The whole Dissociative Disorder angle was the book’s central dilemma – is it real or just a ruse by the patient to dodge the death penalty? Meanwhile, the backdrop of serial murders, mostly of marginalized young women, adds another layer to the story, especially since Stevenson’s own daughter fits the victim profile. I wished there had been more exploration of this subplot, though. And the big question that kept nagging at me: If the patient’s so savvy as to juggle four personas, why’d they let themselves get caught? Even though Stevenson’s job isn’t to play detective, both she and I couldn’t help wonder if the patient (or any of his 4 personalities) was the real killer. And let me tell you, the best twist in the book comes right when you least expect it. If you enjoy reading suspense with a twist, this one’s definitely worth your time.
