The Underdog Detective Agency has a proud tradition of sniffing out trouble (and sniffing each other's butts).
Detective Barkley (a dog) and Detective Fang (a cat) are cleaning up the mean streets of Dogtown one crime at a time!

When the DogAid music festival arrives in Dogtown, the Underdogs are called in to help rock legend Mick Wagger of the Rolling Bones! Mick's golden guitar is missing. Has it been stolen? If so, by who? And why? With many rival musicians in town it could be almost anyone! Was it Justin Beaver? Or maybe it was Catty Perry? Can the Underdog's crack the case and help the show go on?

Join Detectives Barkley and Fang in the fourth instalment of this hilarious, action-packed and highly-illustrated series.
