This is the fourth book of the succesful mystery series Madame Storey, by canadian-american author Hulbert Footner. Almost unknown today, Footner was a Candadian journalist and author of many adventure and mystery novels.
In The Doctor Who Held Hands Madame Storey is asked to help in stopping the pseudo-psychological activities of a doctor who has set himself up as a psycho-synthetist, seemingly to help his patients, but in fact blackmailing them... Storey is almost imprisoned in her movements from the very start giving the story a bit of claustrophobic feel until little by little she finds a way to break out of the surveillance.
