Appointment with Death

Context:

Referenced for a key quote from the character Dr. Girard, a French psychologist, who says: 'There are such strange things buried down in the unconscious, a lust for power, a lust for cruelty, a savage desire to tear and rend. We shut the door on them and we deny them conscious life. But sometimes they are too strong.' The hosts use this to illustrate Christie's mid-century preoccupation with hidden evil within ordinary people.
