82. The Fire Raiser, by Maurice Gee.

When fires start being lit in the small town, everyone is busy trying to figure out who is behind them. Some lucky schoolkids happen to be in the right places at the right times, and are able to put together the pieces to point out the culprit. But he's not going to give up without a fight.

This is very much a children's book, and the writing reflects this. I found it a bit dull and far too convenient in places, but I imagine it would suit a younger audience more thoroughly. It was written quite well, but there are more than a few plots that are starteed in various places and never finished, which makes me wonder why he bothered to include them at all, since several of them don't actually contribute much, and leave more questions unanswered than they actually help. Maurice Gee is an author I've heard good things about, but on the basis of this book alone, I would find it hard to gather much enthusiasm for his work.
