Murder is again polluting the Exeter Cathedral close, but this killer will not be easily caught. The victim, Henry Potell, was feared by many, and held secrets that some wished to keep hidden. For Sir Baldwin Furnshill, Keeper of the King's Peace, and his friend Bailiff Simon Puttock, events become increasingly mysterious. Who among Henry Potell's companions knows the truth about his death? What first appears to be a matter of lust or greed soon grows more troubling as Baldwin becomes aware of the ominous Chapel of Bones, built long ago in reparation for a terrible murder.
