A sadistic practical joker is deliberately ruining acts at London music-halls, with stunts ranging from the mildly humiliating to the positively dangerous. Cribb receives a note to say that an accident is about to happen and turns up at the theatre just before a murder. His investigations lead to activities which certain people are keen to keep secret, involving after hours performances for the great and the good of a decidedly sexual nature.
