Talking to a popular crime writer like Harlan Coben is always a tricky proposition. With plenty of unexpected twists and turns in his books, you always have to tread carefully to avoid giving away too many secrets. However, with more than 20 best-selling novels to his name, the New Jersey-based author believes he can always get one over on the reader.
"It's a hard thing to do because you also don't want to play too coy because that's not fair either," he says. "Whatever questions people have I usually answer but I find that even if you know some of the answers from spoilers, I'll still fool you. The ending will still fool you - and I pride myself on doing that. But hopefully you'll also be genuinely moved, which is also my goal. It's not just to show sleight-of-hand or narrative tricks, although I will do that, it's also to make you care about what happens to the characters."
His latest effort, Six Years, is a good case in point. Centring around university professor Jake Sanders, it hinges on the promise he makes to the love of his life at her wedding to another man that he will leave her alone from that day onwards. He keeps the pact for six years - until he reads her husband's obituary in a newspaper and it becomes apparent that the dead man's wife and Jake's former beau are not the same person. "I usually tell people that it opens with immediate heartbreak," says Coben. "It came about because I wanted to write a love story that was also a thriller. The last time that I did that was with Tell No One, which was a pure love story that happened to have some surprises."
Coben believes Six Years bears comparison with his 2001 breakthrough book, the first of his novels to appear on the New York Times best-sellers list, turned into a film by French director Guillaume Canet in 2006. "It's certainly as strong as Tell No One," he says. "Actually, if you've not read any of my stories, this one is as a good place to start as you don't need to know anything beforehand."
