Dissolution by C.J.Sansom
The Hunchback of Westminster...
Had it been situated in the Middle Ages, it would have been a mixture of Ellis Peter's Cadfael and Umberto Eco's The Name of the Rose.
A crime has been committed in a monastery, and a commissionner has been sent to solve the problem.
The difference lies in the fact that it's under Henry the VIIIth, when he decides to dissolve the convents and monasteries, officially to make papists disappear, but, unofficially, to gain territories and money.
And it's this atmosphere that is really interesting in the book, because the clues of who the murderer was are given very early in the book, and the suspense is not enormous.
What is interesting, is the way a strong reformer like Shardlake, a follower of Cromwell, ends with less convictions, so that he even, for a brief moment, thinks a relic could cure his infirmity...
Apparently, the Tudor times are quite fashionable nowadays, with all the films and books around the Boleyns ( we have the second season of "the Tudors" on TV at the moment ) and around Elizabeth the first.
I'm not complaining, as I like this period very much. Even if the French, in the books and films are always the villains...
