The Amazing Dr Clitterhouse (1938) MKV DVD (Quality)

Dr. Clitterhouse is a brilliant, well-respected Park Avenue physician who becomes obsessed with understanding the psychology of the criminal mind. He burgles the homes of four high society acquaintances, stealing high-end jewelry in order to gauge his own physiological reactions to the experience, which he finds exhilarating. On his fourth robbery he crosses paths with professional thieves and seeks out their leaders, Jo Keller, a woman fence, and Rocks Madison, a vicious sociopath. They form an unholy alliance: Clitterhouse masterminds the high-end robberies, which greatly increases the gang's take, while the Runtonesque thieves allow themselves to have their blood and vital signs monitored. Keller's growing attraction to Clitterhouse and the loyalty the gang shows him feeds Rock's growing resentment at being displaced, and his growing paranoia pushes him to try to commit the greatest crime of all, homicide.
