Dragnet S01E05 - Cardiac Arrest

Daniels and Molina are called to the upscale Mayfield Hotel, where Steven Lewis was found dead from an apparent heart attack. Although the case seems routine, a few small details — the doctor leaving the scene hurriedly because he can't stand the sight of a dead body, and the victim never being seen the hotel staff — don't add up and, during a lull in police work, the detectives decide to look deeper into the deceased's life.
