The Case of the Howling Dog (Perry Mason, #4)

Compared to a juicy murder trial, a case of feuding neighbors isn't exactly Perry Mason's cup of tea. But Arthur Cartright insists that Mason is the only one who can muzzle the howling police dog that's driving Cartright crazy.

Perry doesn't realize just how crazy until he meets his client's neighbor, Clinton Foley. Foley says emphatically that Cartright is barking up the wrong tree with his canine complaint -- and swears that the man is dangerously insane to boot.

Mason's not the type to cop out on a client -- but when Cartright draws up a will that leaves everything to this neighbor's wife, even Perry had to wonder if the man had slipped from anger to madness. That's why he pays a personal visit or two to Clinton Foley's house, where he eventually finds a missing wife, a dead dog, and a corpse!
