There could only be one suspect in McGruff's eyes: the canine crusader Underdog. As hard as it was to accept that a mutt who'd so tirelessly championed justice could do something so dastardly, it was a well known fact that Underdog drew his powers from the same kind of pill, and even if he was not the distributor, he was most certainly the source.
The trick was finding Underdog. It had taken a while, but after questioning Underdog's known associates, like Sweet Polly Purebred, as well as the head of the drug operation, Riff Raff, he had finally learned Underdog's secret identity: humble, lovable Shoeshine Boy. McGruff should've known; there weren't that many talking beagles in town, after all.
McGruff turned a corner and there was Shoeshine Boy, a friendly smile on his face, hard at work shining the shoes of a customer.
"Stop right there, Underdog!" growled McGruff, "I'm taking you in for questioning, and I'm confiscating that ring of yours!"
"I know this case may seem airtight" said Underdog, as his zipped into a nearby phone booth, emerging an instant later in costume, "But all your facts are not quite right. I'm not the fiend behind this plot! Bar Sinister is the man you sought!"
"A likely story pup," retorted McGruff, "now are you gonna come quietly, or am I gonna have to take a bite outta crime?"
You decide, dear readers! Dog vs. dog! Who emerges victorious?
