I might never have discovered James Munro’s John Craig thrillers had I not seen the film of the last of them, The Innocent Bystanders, in early 1973. Christina Foyle remarked at the time of Craig’s first appearance in The Man Who Sold Death (1964) that his creator wrote like a cross between Ian Fleming and John le Carré, but although the book and its successors were well-received, Munro never found the same fame. The film sank without trace, despite an excellent cast headed by Stanley Baker, but it did inspire me to seek out the Craig books. I loved them.
