Something is not right at Beechway psychiatric unit. First one resident turns violently to self-harm, then another to suicide—both recalcitrant patients with no prior history of self-directed violence. Whispers between the inmates have traveled to the staff that the place is being terrorized by a creature called The Maude. Clinic higher-ups dismiss this as superstition, but the surviving victim certainly saw something. And what of the drawing the dead woman left behind, showing the creature wearing the sweater of a recently released patient? When staff Nurse AJ LeGrande calls on Detective Jack Caffery to investigate, what he learns about what’s going on inside and outside the hospital will shock readers and place individuals beyond the ward walls in danger. And what of Flea Marley, the police diver whose dark secret Caffery has been keeping? Can he save her from herself, or will she take him down with her?
