Having read the definitive (well, perhaps not) account of what happened just after the Battle of Hastings by Howard of Warwick, I loved this book too. It features a young monk, Hermitage, living in a monastery run like a prison camp. Hermitage is unfortunately present when a senior monk dies, apparently naturally. The hilarious tale of what follows takes in a plot that emerges only slowly, but that doesn't matter as the story has so many funny moments and twists and turns that it keeps the reader guessing - and chuckling - all the way through. Even King Harold, taking a break from his journey south for his punch-up with William, gets in on the act. Will Hermitage be hung for murder, will he unmask the real killer, what is Wat, who on earth are the main characters really, and what are they all doing there? All these and more are finally revealed to a greater or lesser extent, and none of it matters anyway, because this is such a fun book.
