Priceless

It is 1908, and Prince Maurice de Jurat has been murdered -- drowned and his body thrown before the high altar of the Cathedral at Bayeux, a stiletto through his neck. What's more, Jurat's beloved painting -- Da Vinci's "Madonna of the Yarnwinder"-- has gone missing. Who killed the Prince? And who took the painting? And are they one in the same person? All questions to tax the intellect even of the greatest detective of the Belle Epoque.
