'Some wise guy - Confucius or somebody - said there was nothin' like the truth, which is a thing that I believe in - sometimes. Anyhow, I am goin' to try this nothin' but the truth stuff on this dame I spoke to. What can I lose, anyway?' When Julia Wayles is kidnapped in the US and taken to England, FBI agent Lemmy Caution finds himself caught up in a tangled web of intrigue and international espionage. Julia is being held by two American mobsters, who may or may not be who they say they are. And as usual it's the dames in the story who distract Lemmy from business.
