There's plenty to like in this second book in the Oxford series, and I found myself gripped much of the time. The story does lose its way a little in the final quarter, but the last (short) chapter contains a spectacular surprise when the identity of the bad guy is revealed.

There's less humour here than in the first book, although that is rectified whenever Sarah appears. And as previously, the characters are well drawn and distinguished from each other.

Another gripping yarn -- recommended.
