Backside of Thursday

There was this white dog with a puppy cut. It was found mutilated at the top of a tree. How did it happen? That''s the mystery. No murder mystery though. After all, it''s a dog. Dense PI Jack and his smart lady friend Julie, clueless cops, Birdman Fritz, Jungle Tom, and others make for mystery as farce. It''s all humor about a dimly lit time and very gray place. Who says so? I do. Who? The author of a "how did it happen" rather than a "who done it."
