The Complete Audiobook in one file, for those who like it that way. “I KNOW WHAT YOU DID” The writer of the mysterious letter could have been talking about any number of misdeeds, some large, some small, some frankly unsuitable for print. When it comes to deeply unqualified guardians of the moral high ground, it would be tough to find many that equaled Black Jack Justice and his erstwhile partner, Trixie Dixon, girl detective. But they will learn the hard way just how serious the sender was, and that in the end, only Dead Men Run.
