Silhouette in Scarlet by Elizabeth Peters

One of my favorite heroines is back again. Vicky Bliss is on the case once again as she's searching for a lost cache of Scandinavian treasure. One perfect rose (not, alas, a limousine for either she or Dorothy Parker) sends her off on a trip to the land of her ancestors. A trip where she encounters a lost love, a bad guy who does silhouettes, and an extended stay on a millionaire's island. 

Another great story and very enjoyable as an audiobook, not as good when I reread as a physical copy. Rosenblat makes the angst fun but it was a little overwrought in the written word.
