Prominent London psychoanalyst Dr. Leo Whitset is discovered injured from a gunshot wound in his home by his housekeeper, and as he lies dying he whispers, "Blame no one but me." These words lead the coroner to rule the death a suicide, a verdict questioned by one of Dr. Whitset's patients, Alex Stedman, a popular American news commentator for British television who has been in therapy since the deaths of his wife and daughter. The dead man's fourteen-year-old daughter Catherine is certain he was murdered and enlists Alex's aid in finding the killer to preserve her father's reputation.
