The Crispin Guest Medieval Mysteries

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.

Since losing his knighthood, Crispin Guest has crafted a new reputation for himself. From the shadowy corners of London to the halls of the royal court he is known as the Tracker, an investigator for hire who can find anyone or anything. But when the Archbishop of Canterbury hires him to expose the culprit threatening the sacred relics of a holy martyr, Crispin finds himself a stranger in an unfamiliar land.

Private investigator and former knight Crispin Guest faces his most complicated case yet when he witnesses a body fall from London bridge into the frigid River Thames. Though the man's death is declared a suicide, Guest sees evidence of foul play. His investigation leads him to Sir Thomas Saunfayl, an old acquaintance from his knighthood days. It seems the dead man was bargaining with Sir Thomas for the Spear of Longinus, the weapon used to pierce the side of Christ on the Cross, which grants invincibility to its owner.

After losing his knighthood, Crispin Guest has found a new calling as the Tracker, a private investigator who can locate anything—or anyone. Now famed French alchemist Nicholas Flamel needs Crispin to locate his wife, Perenelle, and his apprentice, Thomas Cornhill.

The kidnapper promises that Flamel's wife will be next...unless he hands over his precious Philosopher's Stone, a magical object that can turn lead into gold.

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.
