This is a unique Cadfael book because the good Brother does very little investigating, and is a largely passive observer in the sequence of events. The murder is a minor note in this story of Owain the Welsh prince, his estranged brother, their assorted liegemen, and a force of invading Danes. Cadfael and Brother Mark do have a minor role (as diplomats and hostages), but they are not major actors.

This actually works fine, though, and the story is a good one. Even as an observer, Cadfael holds the reader's interest, and Owain is a compelling character. Plus the romance is nicely done. But above all, I enjoyed the Welsh politics and the negotiations between Owain and the Danes.
