Screenplay by PHILIP BROADLEY   Directed by PAUL DICKSON     Interpol agents are not the sort of men to commit suicide—so why should three apparently do so? The Champions find the answer in Italy.     Three Interpol agents kill themselves—for no apparent reason. The three Nemesis agents, Craig (STUART DAMON), Sharron (ALEXANDRA BASTEDO) and Richard (WILLIAM GAUNT) are assigned to the case and find that the dead men had only one connection apart from being Interpol agents: all had, separately, brought accusations against a Mafia leader named Del Marco (EDWARD BRAYSHAW). When another Mafia leader commits suicide, followed by the death of his girl-friend (JEANNE ROLAND), the Champions are convinced that Marco is involved and make contact with him. Craig poses as a man hell-bent upon revenge because his brother has been killed by Marco and thus deliberately establishes himself as someone Marco needs to dispose of.   Sitting in a cafe, Craig is approached by the Mafia leader’s bodyguard, Umberto (JOHN BAILEY), who pleads with him to go home. Craig refuses, and the two men shake hands.   Craig then discovers that there is a smear of grease on his hand—obviously placed there by Umberto. Five minutes later, he has a strange urge to kill himself and, making his way to a roof-top, is about to jump when Sharron and Richard stop him. Their telepathic powers have warned them of his danger.   Sharron examines Craig and comes up with the solution: the grease smear is a drug which has affected his blood-stream—a drug making people want to kill themselves. This, then, is how Marco has killed the Interpol agents.   Umberto, they learn, is a crooked doctor, and therefore the man who has discovered this deadly formula. And it is through him that they bring Del Marco’s reign to an ironical end. The name of their organisation has peculiar significance: Nemesis!     AN PRODUCTION   Series created by Monty Berman and Dennis Spooner   © Copyright Incorporated Television Co. Ltd.
