Screenplay by PHILIP BROADLEY   Directed by CYRIL FRANKEL     The Champions probe a Caribbean conundrum. Who wants a parrot that speaks Greek?     A man is stabbed to death in a Montego Bay hotel. He had been travelling on a French passport, posing as Jean Valentin, a French businessman dealing in plastics. But he has been identified as a formidable and dangerous G.P.U. agent, specialising in all uses of explosives, by the name of Semenkin.   What was he doing in the Caribbean? It’s a problem for Nemesis to solve, and Craig (STUART DAMON), Sharron (ALEXANDRA BASTEDO) and Richard (WILLIAM GAUNT) are sent to Jamaica to investigate, with Craig masquerading as Semenkin.   The first mystery is a personal add in the dead man’s possession: “Wanted, A parrot that speaks Greek. Reply Box No. 666.” But why has Semenkin inked the figures into eights?   Craig’s investigations take him to a gift shop run by a man named Nikko (GEORGE MURCELL), believed to be Semenkin’s contact, and he is right in his guess that the parrot advertisement is a code to identify Semenkin. Craig is accepted as the G.P.U. agent and meets Jules (ANTON RODGERS). One thing becomes clear: they are searching for something in Montego Bay. But what? Craig has to go carefully to avoid revealing his lack of knowledge in this respect as they fly over the bay, piloted by the attractive Corinne (NIKE ARRIGHI). When his masquerade is detected, Craig is shot in the back and dumped overboard.   Sharron senses that something has happened to Craig but her intuition tells her that he is, in fact, alive and she and Richard are able to plot his approximate whereabouts. He’s very close to one of the smaller, uninhabited islands.   There is, however, one inhabitant on the island, as Craig discovers when he struggles ashore: a native named Clive (LINBERT SPENCER), who treats his wounds and tells him of a ’plane that has crashed on the other side of the island.   Is this the object of the intensive search? When Craig reaches the wreck, he realises that it is—and why Semenkin had been sent to blow it up and thus destroy its secrets. But by now, Jules and Corinne have spotted it, and it’s a race between them and Richard and Sharron to get to it first...     AN PRODUCTION   Series created by Monty Berman and Dennis Spooner   © Copyright Incorporated Television Co.
