Thief's Mark by Carla Neggers

We've learned a lot about Oliver York in the previous 6 books in this series. In this book, he comes into even more focus when one of the man who kidnapped him as a boy, returns. And then dies in Oliver's arms. Oliver is the easy person to pick as prime suspect. But there is, of course, more to the story.
Emma Sharpe and Colin Donovan are on the last day of their honeymoon when the call comes in that Oliver is once again embroiled in a mystery. Also on the scene, Oliver's gardener, Henrietta, (a former British secret service agent) and a man who has been with him since childhood, Martin.
 Weaving together the characters that Ms. Neggers has created in the Sharpe and Donovan universe, the dead man visited Father Finian the day before he died. I like that there is a concrete reason for previous characters to be woven in, they're not just plugged in willy-nilly to remind you that this is a series.
Books can always be read out of order in a series but I definitely wouldn't recommend it for this one. I think regular Neggers readers are going to be pleased with this addition to the series.
