Hollywood gumshoe Toby Peters - who has played sleuth to such movie luminaries as Humphrey Bogart, the Marx Brothers, Bette Davis, Mae West and Charlie Chaplin - now finds himself working for Cary Grant.

The assignment seems simple enough - Grant merely wants Toby to deliver a package and pick up an envelope in the middle of the night. But at the critical moment of the exchange, a shot rings out and Toby finds himself with a corpse on his hands, a lump on his head, grass in his mouth and a dying man's words on his mind.

Now in pursuit of a murderer, Toby and Cary Grant follow a trail of clues that leads them to a second dead body, a nest of Nazi sympathisers, and finally to a night-time confrontation with a determined and well-armed killer on the grounds of an estate at the edge of Laurel Canyon.
