'The Trust' (ITV, tx. 2/11/1983) Written by Troy Kennedy Martin, Directed by Martin Campbell

Sidney Reilly moves to New York, running a successful business and also helping to raise funds for the anti-Bolshevik organisation headed by his friend Boris Savinkov. He also tracks down possible infiltrators who are being sent around the world by the authorities in Moscow. In 1924, collaborating with the FBI, Reilly rounds up a group of new arrivals from Russia. He picks out Lieberman, a friend of Savinkov, and has General Monkowitz take him to a safe house.

In London, the copy of a letter signed by Gregory Zinoviev, chairman of the Cominterm in Russia, is acquired by Cummings, head of the British Secret Service. He is convinced that the letter, which calls on all British workers to revolt, is a forgery, despite Reilly's claim that it is genuine. Cummings believes that it is an attempt to undermine newly drafted trade agreements with Russia.

Reilly hires Eugenie as his new secretary on the recommendation of Savinkov's close friends Mamie and Dichter Daerenthal. He is suspicious of her, however, and asks Cummings to check out her background. Reilly goes to see Lieberman, but finds that he has been killed under interrogation by Monkowitz, expressly against Reilly's orders. Reilly's wife Nadia arrives in New York and asks for a divorce. In return for his agreement, he asks her to set up a meeting with the industrialist Henry Ford.

As Savinkov prepares to leave for Europe, Reilly warns him that the Daerenthals and others of his friends are really working for the Bolsheviks and that the supposedly sympathetic group named 'The Trust' is really run by Communists. He begs Savinkov not to accept any offers from 'The Trust' of safe passage to Russia, as it will surely be a trap.

After meeting Ford, Reilly is ambushed by Monkowitz. Reilly kills him and then shoots Eugenie when he realises that only she could have given out his schedule that night. Reilly goes to Berlin to meet Savinkov, where he also meets Pepita, his future wife. Savinkov tells him that he feels he must accept the offer from 'The Trust' to go home to Russia. 'The Trust' is in fact a Communist front and Savinkov is arrested. Cummings confronts Reilly with the Zinoviev letter and asks him to repudiate it. Reilly refuses and when it is made public it leads to the fall of the British government.
