"The Good Doctor" (2011)
"An orderly, Jimmy, discovers a diary in which Diane had recorded her feelings towards Martin. Recognizing that even the implication of an improper doctor-patient relationship could potentially damage Martin's career, Jimmy uses the diary to blackmail Martin into providing him with narcotics. When Jimmy reveals that he intends to never hand over the diary, Martin laces the drugs with potassium cyanide and kills Jimmy, then breaks into his locker and steals the diary.
During the course of the criminal investigation in Jimmy's death, Martin is questioned by a police detective who comes to visit him at his home. Martin becomes panicked and visibly awkward during the questioning, eventually locking himself in the bathroom and attempting to flush the diary down the toilet. When the toilet clogs, Martin climbs out the window and goes to the ocean, where he contemplates suicide. Instead, he sneaks back into his apartment and puts the diary in the garbage."
