He started writing novels in 1951 and in 1953 had considerable success when his best-selling 'The Sea Shall Not Have Them' was filmed. He went on to write many more war and modern adventure novels under his own name, and also some authoritative non-fiction, such as 'Dunkirk'. Using the name Max Hennessy, he wrote some very accomplished historical fiction and as Mark Hebden, the 'Chief Inspector Pel' novels which feature a quirky Burgundian policeman. Harris was a sailor, an airman, a journalist, a travel courier, a cartoonist and a history teacher, who also managed to squeeze in over eighty books. A master of war and crime fiction, his enduring novels are versatile and entertaining.
