Edited highlights following the first consultation and treatment of a patient who was greatly troubled by this condition. She initially presents with two phobias, of peanuts and glass but later on refers to hand washing and other rituals.

Discussion of the triggering and maintaining factors, and the dangers of any psychotherapeutic endeavour are also included.
