Thorne: Sleepyhead raises an interesting question. How long should a TV adaptation of a crime novel be? It's not really an academic question - it can made a great deal of difference to pace and suspense. The definitive TV tec show of recent times remains Inspector Morse, which began with each book turned into a single two hour show. Lewis follows the same pattern to this day, even though the screenplays have been original since TV ran out of Colin Dexter's originals many years ago.
Sometimes a novel may be squeezed into an hour - less if there have to be commercial breaks. Some years ago, one of the various TV deals relating to my books that never made it to the screen was based on the premise of 60 minutes per novel. It seemed a bit tight to me, but in the end it never got beyond the realm of theory.
Recently, DCI Banks turned a Peter Robinson novel into two hour-long episodes. The first seemed better than the second, which became a bit melodramatic. Thorne, however, turns Mark Billingham's book into three hour-long episodes. A bold move. The danger is that the story becomes very padded out if you aren't careful.
So far, however, so good. The second episode was fast-moving and pleasingly complex. It managed to hold my attention from start to finish, no mean feat on a somnolent Sunday evening. It's a good story, well translated to TV, and I'm enjoying it. Let's hope the final episode reaches the same standard.
