Our hero Libertus returns for another sleuthing mission on behalf of his patron. Previous reviewers have done more than justice to the book, so I'll just add that although I had an idea who the perpetrator was, the motive wasn't obvious and I missed the clue which cracked the case. It was enjoyable walking the streets of Glevum with Libertus and soaking up the atmosphere of everyday life in Roman Britain - this is one of her strengths as a writer I think, invoking period and character. As usual I with a Libertus book, I read it in one day - unusual for me as I generally have two or three books on the go and dip in and out of them. She really does deserve to be better known.
