A missing Holy Relic. A mysterious and beautiful woman. Two murdered monks: Crispin Guest tackles his most intriguing investigation to date.

1390. Hailes Abbey, Gloucestershire, England. Two monks lie murdered, their Holy Blood relic stolen: a relic that is said to run liquid for the sinless and remain stubbornly dry for the sinner. Unwilling to become involved in a bitter dispute between a country monastery and Westminster Abbey, the disgraced former knight Crispin Guest attempts to return the relic to Hailes where it belongs, but somehow it keeps returning to his hands no matter what.

As he tries to shield a former nemesis from a charge of murder while becoming entangled with a mysterious and beautiful woman caught between Church politics and the dangerous intrigues of King Richard?s court, Crispin begins to suspect that someone at Westminster is conspiring with the assassins. Can the Blood of Christ point to the killer?


“Fans will welcome [Westerson’s] hero’s return in his 10th reliquary adventure.”


“Fans of 20th-century noir will relate to Crispin, who doesn’t say no to a drink and is a sucker for damsels in distress.”

Publishers Weekly

“If you like historical mysteries where you really feel (and occasionally taste and smell) just how different the past is from our own present, Crispin Guest is a master at bringing his world to life — and solving its suspicious deaths.”

Reading Reality

“This is another excellent addition to both the Crispin Guest series and to the canon of medieval mysteries overall. Highly recommended.”
