The disgraced knight turned inquiry agent searches for a missing relic in this Macavity Award-finalist mystery set in fourteenth century London.

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. In a world full of old friends, mysterious strangers, and dangerous enemies—including the treasonous mastermind who caused Crispin’s fall from grace—Crispin will have to uncover a deadly conspiracy to protect his country, save himself, and perhaps even restore his good name.

The Crispin Guest Medieval Mysteries

Serpent in the Thorns

A medieval knight turned private investigator is joined by Geoffrey Chaucer in his latest case featuring “clever twists and convincing period detail” (Publishers Weekly).

 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 his friend Geoffrey Chaucer arrives in London, all too eager to help find the spear, Guest finds himself trying to solve a conundrum of many parts, all centered around the same dangerous and coveted relic. With evocative period detail and an unforgettable cast of characters, Blood Lance was a Kirkus Reviews “Top 10 Hot Crime Novels” of Fall 2012.
