When a corpse turns up at his favorite tavern, Crispin Guest—disgraced knight turned detective--begins an inquiry, but the dead man turns out to be a Templar knight, an order thought to be extinct for 75 years, charged with protecting a certain religious relic which is now missing.

Before he can begin to investigate, Crispin is abducted by shadowy men who are said to be minions of the French anti-pope. Further complicating matters are two women: one from court with an enticing proposition, and another from Crispin’s past, dredging up long-forgotten emotions he would rather have left behind.

And as if all that weren’t enough, a cunning young cutpurse by the name of Jack Tucker has insinuated himself into Crispin’s already difficult life. The deeper Crispin probes into the murder, the more it looks like the handiwork of an old friend turned adversary.

With enemies from all sides, Crispin has his hands full in more than murder in this intriguing prequel to the acclaimed series.
