From internationally bestselling author LJ Ross comes the third book in the gripping Alexander Gregory Series―a fast-paced thriller set amidst the spectacular Catskill Forest. In a world turned upside down, who can you trust? Fresh from solving a high-profile case in Paris, elite forensic psychologist and criminal profiler Dr Alexander Gregory is pulled into another nightmare. The FBI is on the brink of losing its biggest trial yet: the wife of a notorious criminal―their star witness―has been committed to a private psychiatric hospital and declared unfit to testify. Without her, their case collapses. Buchanan Hospital is locked down tight, and its formidable staff are as secretive and unpredictable as the patients they treat. With no one left to trust, the FBI has no choice but to turn to Gregory. Now he must enter the hospital and untangle a web of manipulation and murder before the clock runs out. But inside these walls, nothing is what it seems―and once he uncovers the truth, he may not walk away unchanged. Set within the looming pines surrounding the Catskill Mountains, this razor-sharp thriller proves that sometimes the most dangerous secrets are the ones locked inside the mind.
