"In matters of courage, there is no bigger dog than me!" P.I. Geri Sullivan and her talking Chihuahua, Pepe, are always hungry to sink their teeth into a new case. So if helping a hapless husband win back his wayward wife means sneaking into a cult of dog-worshippers, porque no? Inside the believers' rural retreat, Pepe perks up his ears when the charismatic leader pegs him as the next incarnation of the spirit Dogawanda. But the discovery of a body, murdered between mantras, suggests there's more chicanery than channeling going on in this suspicious sect. While wild wolves howl, a killer is on the prowl-and it's up to Geri and her canine compadre to dig up the dirt.
