Summer 1225. Change is in the air. There is a new religious force in the the preaching friars. When the first of these arrives in Bury he is greeted with suspicion by some of the monks. What does he want? Why has he come to Bury?
Their mistrust seems justified when strange things begin to happen. The abbey comes under attack from a plague of rats and deadly poisonous gas.
Then one of the monks is murdered.
The prior attempts to calm nerves by appealing to the saint whose name the abbey bears. Is it the new friar who is doing these things or is there some supernatural power at work?
Walter is not convinced and decides to investigate. Only when all the children of the town suddenly disappear is the truth at last revealed.
This is a fun read and a good mystery. The story is written as a memoir/chronicle by Brother Walter and I like how the mystery spins out. The "reveal" is not a dramatic presentation (such as in an Agatha Christie story), but rather as an epilogue. I've read all the prior books in this series, and my quibble with the author is that he jumps around in time. In a prior book Brother Walter dies in the conclusion. In this book we've gone back in time and he has to contend with smarmy Prior Herbert and eccentric Brother Rufus. I miss the continuity of supporting characters in these stories, but taken as a whole, each story is well-written and a fun read.
Since Walter died in a previous book, I was surprised and pleased to see a new mystery. I thought it might seem odd to read a book that was chronologically out of order, but it wasn't. I guess Walter is timeless. Keep them coming and I'll keep reading them.
