A mystery serial in six episodes by Raymond Bowers.
Starring Sebastian Shaw, Petra Davies, Derrick Sherwin and John Cairney with Patrick Magee

Clare had gone with Tony, the trumpeter at 'The Zombie', to his flat to try to find out more about the disappearance of Miss Sabry. She left Tony's flat-unaware that Miss Sabry was actually there in a cellar bedroom.
Paul, Clare's step-brother, angry at the attack upon him at 'The Zombie', and thinking it was Cracker's handiwork, told Cracker that he would let him have only five thousand pounds and not ten as promised. He could not raise any money at all for four days.
Later, leaving 'The Zombie' with Clare, Cracker received a final demand for five thousand pounds, and a warning that Miss Sabry would be killed if he failed to pay that night.
