description About

Kirby, Fane, Vincent and Laura travel to Normandy to listen to Madame Lafois' claims that Fane's American political adviser is actually an undercover Soviet agent, but learn that the old woman died after meeting with Kirby the previous weekend. Fane accuses Kirby of defaming Vincent and killing the French informant himself. The real traitors then force the rest of the party onto a remote beach with plans to kill them all.
