A sadistic practical joker is haunting the popular music halls of London, interfering with the actors and interrupting their acts by orchestrating humiliating disasters that take place in view of the audience. A trapeze artist misses her timing when the trapeze ropes are shortened. A comedian who invites the audience to sing along with him finds the words of his song shamefully altered. Mustard has been applied to a sword swallowers blade. A singers costume has been rigged. The girl in a magicians box is trapped. Then the mischief escalates to murder. Or was murder intended all along? That indomitable detective team, Sergeant Cribb and Constable Thackeray of Scotland Yard, must track down the elusive criminal.
