Crispin Guest

Accused of treason and stripped of his knighthood, Crispin Guest has survived on the gritty streets of London by reinventing himself as The Tracker, an investigator for hire who can locate lost objects and uncover secrets. When the merchant Nicholas Walcote hires Guest to investigate his young wife Philippa for adultery, he discovers an underground world of danger and dirty dealings. Philippa is indeed hiding something—but she's not the only one. Walcote himself is rumored to possess a holy relic so powerful that some would even kill for it.

Former knight Crispin Guest is now known in the streets of medieval London as the Tracker—an investigator who can find anything and anyone. What begins as a straightforward case of murder turns complicated when Crispin realizes that the victim was an important courier in possession of a holy artifact—an object so valuable that its absence could start a war between France and England. Surrounded by possible suspects, Guest will have to use his wiles to navigate both the exclusive halls of King Richard's court and the hardscrabble streets of fourteenth-century London.

Since losing his knighthood, Crispin Guest has reinvented himself as an investigator for hire known as the Tracker. But his reputation will once again be put to the test with his latest case. Jacob of Provençal, a Jewish physician at the king's court, is missing a set of documents that he claims contain the power to bring forth a dangerous demon. Meanwhile, it seems a monster has already been unleashed on the city. Vulnerable street children are being abducted and murdered, their mutilated bodies the only clues left behind.

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.
