I met Chet the dog yesterday. He's the narrator of Spencer Quinn's The Dog Who Knew Too Much.
Chet's a K-9 reject with an excellent nose and perfect loyalty to Bernie Little. Together they are the Little Detective Agency. Here they find themselves searching for a lost boy, which leads them into all sorts of trouble with crooked lawmen and meth camps.
Chet's a charmer with keen storytelling ability, with the occasional lapse of attention when, say, there's bacon nearby, or a swimming hole.
The book was fun. Probably even better for dog lovers.
And here is Peter Abrahams' website, creator of Spencer Quinn and Chet.
