***Crispin Guest is summoned to a London priory to unmask a merciless
killer. Can he discover who is committing the deadliest of sins?
1399*, London. A drink at the Boar's Tusk takes an unexpected turn for
Crispin Guest, Tracker of London, and his apprentice, Jack Tucker, when
a messenger claims the prioress at St. Frideswide wants to hire him to
investigate murders at the priory. Two of Prioress Drueta's nuns have
been killed in a way that signifies two of the Seven Deadly Sins, and
she's at her wits end.
Meanwhile, trouble is brewing outside of London when the exiled Henry
Bolingbroke, the new Duke of Lancaster, returns to England's shores with
an army to take back his inheritance. Crispin is caught between solving
the crimes at St. Frideswide's Priory, and making a choice once more
whether to stand with King Richard or commit treason again.
