Sometimes an author falls in love with one of his characters and finds it hard to let him or her go. Such is the case in this second to last Flavia And Jonathan adventure. Pears brings back his master thief from The Giotto's Hand to support a somewhat good plot but unfortunately the character's presence only annoyed me instead of adding to the tale. And what a tale it is. A forgotten monastery in the heart of Rome, an obscure order with a dubious Caravaggio and a miraculous icon worshipped by the local people. Jonathan and Flavia unravel the different threads to a satisfying end if it wasn't for the intrusion of the master thief in the story.
