C. J. Sansom's bestselling adventures of MAtthew Shardlake continue in the fourth title of the series, the haunting Revelation. This is another of my favourites in the series.

Shardlake is working for Archbishop Cranmer and along with his side kick, Jack Barak (a lovable rogue) gets trapped in a horrific mystery. As they follow a trail of dead bodies they quickly find themselves shocked and sickened by the hideous crimes that seem to have religious and demonic connections.

Why is this one of my favourites in the series? Because of the horrible crimes ... no, because once again I had to stay up at night to find out what capers Shardlake and Barak were sucked into and worry, worry, worry ....

Here's the details ...

Spring, 1543. King Henry VIII is wooing Lady Catherine Parr, whom he wants for his sixth wife. But this time the object of his affections is resisting. Archbishop Cranmer and the embattled Protestant faction at court are watching keenly, for Lady Catherine is known to have reformist sympathies.

Matthew Shardlake, meanwhile, is working on the case of a teenage boy, a religious maniac locked in the Bedlam hospital for the insane. Should he be released to his parents, when his terrifying actions could lead to him being burned as a heretic?

When an old friend is horrifically murdered Shardlake promises his widow, for whom he has long had complicated feelings, to bring the killer to justice. His search leads him to both Cranmer and Catherine Parr - and with the dark prophecies of the Book of Revelation.

As London's Bishop Bonner prepares a purge of Protestants Shardlake, together with his assistant, Jack Barak, and his friend, Guy Malton, follows the trail of a series of horrific murders that shake them to the core, and which are already bringing frenzied talk of witchcraft and a demonic possession - for what else would the Tudor mind make of a serial killer . . .?
