It's the time of year when the immortal army of the ancient king rides Watling Street and the dead become uneasy in their graves. Indeed, in the far north of Warwickshire, the villagers insist that one dead man returned to kill his only son. Now it's up to Sir Faucon de Ramis, the shire's new Crowner, to run the walking corpse to ground and put him back where he belongs. 

A leper's daughter is found in the well of a dying hamlet, and the only suspect has fled into Feckenham Forest. But the sun is setting, and Warwickshire's sheriff is hunting his new crowner. That sends Sir Faucon de Ramis and Brother Edmund, his prickly clerk, racing for a nearby abbey only to meet the man he least wishes to see at the abbey gates. Before long, Faucon finds himself riding into the dark at Sir Alain's side as they hunt for yet another lost innocent. 

A wealthy merchant has been murdered in his own home, and the suspect has fled to sanctuary in a local church. Enter Sir Faucon de Ramis, the king's new keeper of the peas, to solve the murder, assisted by his prickly secretary, Brother Edmund. This time, the hunt leads Sir Faucon into the upside-down world of a woman's trade where the merchant's wife owns the business - Unheard of! - only to discover he isn't the only one on the hunt.

It's 1194, and Sir Faucon de Ramis, the shire's newly appointed keeper of the pleas, must do his duty and make an official declaration of the cause of a miller's death. Saddled with a clerk who names Faucon his "penance", the shire's first crowner must thread the tangled relationships between the sheriff, the village of Priors Holston, and the priory that once ruled it. As a simple task takes a turn to the political, what seems obvious isn't, and what appears safe turns out to be more dangerous than he could imagine.

London, September 1666. The Great Fire rages through the city, consuming everything in its path. Even the impregnable cathedral of St. Paul's is engulfed in flames and reduced to ruins. Among the crowds watching its destruction is James Marwood, son of a disgraced printer and reluctant government informer. In the aftermath of the fire, a semi-mummified body is discovered in the ashes of St. Paul's, in a tomb that should have been empty.

England, 1920. Eleanor Swift has spent the last few years travelling the world: taking tea in China, tasting alligators in Peru, escaping bandits in Persia and she has just arrived in England after a chaotic 45-day flight from South Africa. Chipstone is about the sleepiest town you could have the misfortune to meet. But then, from the edge of a quarry, through the driving rain, Eleanor is shocked to see a man shot and killed in the distance. Before she can climb down to the spot, the villain is gone and the body has vanished.

Hugh of Singleton, fourth son of a minor knight, has been educated as a clerk, usually a prelude to taking holy orders.

The Sheriff of Worcestershire's thief taker, wily Serjeant Catchpoll, and his new and unwanted superior, Undersheriff Hugh Bradecote, have to find the answer. And as the walls of the abbey close in on the suspects, the killer strikes again....
