Silhouette In Scarlet: A Vicky Bliss Mystery 
One perfect red rose, a one-way ticket to Stockholm, and a cryptic "message" consisting of two Latin words intrigue art historian Vicky Bliss—as they were precisely intended to do.Beautiful, brilliant and, as always, dangerously inquisitive, Vicky recognizes the handiwork of her former lover, the daring jewel thief John Smythe. So she takes the bait, eagerly following Smythe's lead in the hope of finding a lost treasure. But the trail begins at a priceless fifth century chalice which will place Vicky at the mercy of a gang of ruthless criminals who have their eyes on an even more valuable prize. And the hunt threatens to turn deadly on a remote island, where a captive Vicky Bliss must lead an excavation into the distant past—and where digging too deep for the truth could dig her own grave.
Reviews
In this third entry of the series, Vicky Bliss receives an anonymous plane ticket and hotel reservation to Stockholm. She knows that the invite is from Sir John Smythe, introduced in the last book and her somewhat love interest. She goes to Stockholm, discovers what the mystery involves, is led to an island in the north of Sweden to follow up on some leads and most of the action takes place there. The mystery is interesting, the clues are available to the reader, there are plenty of red herrings to make it fun, and the ending is very satisfactory.
I guess there are only a couple of more in this series. I wonder if Ms. Peters will ever write any more or will stick with just the Peabody books?
As with the rest of this series there are complicated intrigues, amazing conicidences, exciting chases and a cliff hanging ending all linked by Vicky wry observations on life and love.
