Events draw to a climax in the traditional mode of the detective story.
And so, Val McDermid's crime comedy draws to a climax in the traditional mode of the detective story. The date of Friday 13th adds to the air of danger and mystery - almost as if it was planned that way.
As the suspense builds. What, we ask ourselves, what is that unfamiliar sound? Is it a mating cry? An alarm call?
In the wild, hunters have to rely on their tracking skills - their eyesight, their hearing, their knowledge of their environment and their experience. Luckily for Detective Sergeant Trotter, he has something more sophisticated to count on.
There's nothing quite like a good murder - apart, of course, from another good murder in a second series -
