W.H. Canaway

Sly and dry intelligence agent Harry Palmer is tasked with investigating British Intelligence security, and is soon enmeshed in a world of double-dealing, kidnap and murder when he finds a traitor operating at the heart of the secret service.

After he is orphaned by an air raid on Port Said during the Suez Crisis, a young boy attempts to go by himself from the Suez Canal to Durban in South Africa where his nearest relative, Aunt Jane, lives. On the way he meets a variety of different people who help or hinder his journey - including an ageing diamond smuggler.
