Dr Ruth Galloway is flattered when she receives a letter from Italian archaeologist Dr Angelo Morelli, asking for her help. He's discovered a group of bones in a tiny hilltop village near Rome but doesn't know what to make of them. It's years since Ruth has had a holiday, and even a working holiday to Italy is very welcome! So Ruth travels to Castello degli Angeli, accompanied by her daughter Kate and friend Shona. In the town she finds a baffling Roman mystery and a dark secret involving the war years and the Resistance. To her amazement she also soon finds Harry Nelson, with Cathbad in tow. But there is no time to overcome their mutual shock - the ancient bones spark a modern murder, and Ruth must discover what secrets there are in Castello degli Angeli that someone would kill to protect.
