A simple job turns treacherous when Toby Peters stumbles upon a corpse
It's a lucky thing that Cary Grant once trained as an acrobat, because Toby Peters's life is in the actor's hands. As the two men sprint through the pitch-dark woods, trying to elude a man with a gun, they come to a canyon ledge. With nowhere to go but down, they scramble over the side. Peters slips, and Grant grabs hold of his wrist. As the killer closes in, Cary's grip begins to falter.
The job began simply. Grant hired the Hollywood detective as a bagman in a blackmailing hand-off. He gives Toby a satchel full of cash, to be exchanged for an envelope of the leading man's secrets - not sexual or financial, but details of his work for the British crown. When the envelope bearer winds up dead, Toby and Cary dive into a complex plot of murder, money, and Nazi spies, which ends with them trapped in an all-too-literal cliffhanger.
