I don't really remember much about the story, or really the Story's, as it was a series, but it was a detective series, kinda like Ponyville Noire, in fact Phillip Finder from Ponyville Noire actually shows up in it a couple of times, at least from what I can remember, or maybe Phillip is actually the protagonist? I can't remember I read these story's a Long time ago. Either way whoever the protagonist is he also has an archenemy, who Is his equal is his smarts. And some time in one of the later story's flash sentry gets involved, gets buried alive in a trap, and the protagonist has to dig him out with his bare hooves. But that's about all I can remember, can anyone help me find this series of story's?
