WHEN I was in my teens and didn’t know any better I dreamed of writing crime novels. I started one. The sleuth was a middle-aged milkman who as he did his early morning round stumbled across a body, as dog walkers tend to do nowadays. My milkman, let’s call him Ernie, was as smart as Poirot and as hardbitten as Marlowe. Through the litter-free streets of leafy suburbia Ernie – the creme de la creme of his profession – would trundle in his cart, telling witnesses and suspects they’d better not bottle things or else. He had his eye on a housewife called Ethel who, in her floral Terylene apron and fuscia-coloured brothel creepers, was the local femme fatale. I could go on but even I could see that having a milkman as a hero was stretching credulity. It was at that point I decided to become the new Dylan Thomas.
