Cowboy Thomas E. Loman arrived in London, but was not as he should be. He had been drugged on both stages of his flight from Arizona to London, via New York. Now in the Airport hospital, all he knows is that The Honourable Richard Rollison (alias 'The Toff') has requested he travel to England, where his Grandpa came from, and 'become rich'. The mystery deepens as it turns out 'The Toff' had not invited Loman, and so he must now investigate and find out who is impersonating him, why, and what their motive is. It soon becomes clear he is up against a ruthless gang who will stop at nothing to prevent him finding out.
