Thrice Shy. Bryce Series of Romantic Mysteries, #3

Stephen's life hangs in the balance and Ann must rely on Mike Heywood, a discredited, former policeman, to help deal with the re-emergence of an old adversary.  Driven to seek shelter in a remote cottage on the Norfolk Broads, Ann with Mike and her newly adopted son are at the mercy, not only of Hank Friedman, but the elements.  Using the Fitz Gilbert rubies as a lure stirs up questions of loyalty and trust.
