A flaw in the blood

Irish barrister Patrick Fitzgerald has been summoned by the Queen, a woman in the grip of fear. Her beloved husband, Prince Albert, lies dying. When the royal coach is violently overturned, nearly killing him and his brilliant young ward, Dr. Georgiana Armistead, niece of the late Dr. Snow, a famed physician who'd attended none other than Her Majesty, he suspects they each may carry within their past hidden clues to a devastating royal secret.--From publisher description.
