For me it's one of the best of the Lynley series. I Had hesitated before buying it Because I Was a bit afraid of what Elizabeth George Would make of Italy. Actually, I Was Given a good surprise. It Brings the novel more richness.
HOWEVER I think the author is making Havers's looks and language a bit grotesque, it's a pity! I did not really appreciate the character of the private detective (I Do not Even remember His Name!)
