Immediately the phone line is dead. Michèle and André rushes to Jarré and when Michèle looks out from a window, she discovers on a car a body. Is it François? In the court yard they turn the body: it's Jarré, smashed out of the window. Later the wounded François arrives at André and Michèle to tell them about Jarré. Nicole recognize in François' sketchbook a drawing of Jarré, a friend of Granville. Nicole confess her affair with Granville, who is the head of "Topaz".
Hitchcock made two different endings. In the first Granville is shot death during a duel in the stadium Stade Charléty into his back by a sniper. In a second Granville goes to Moscow. Universal made a third end in which Granville makes a suicide (off-screen). We see his apartment outside and we only hear a shot.
