In 1990, I watched a drama series on the BBC called Never Come Back. It was a superb Second World War thriller with a fine cast including James Fox, Nathaniel Parker and Martin Clunes. Then about a year later, while browsing in my local bookshop, I pulled a volume entitled Never Come Back by John Mair off the shelf and realized that the television series must have been an adaptation of it. The book had obviously been on display in the shop window for a long time because its front cover was badly faded. I almost put it back on the shelf. Thank goodness I didn’t, because Never Come Back (1941) has since become one of my favourite novels.
