The Resurrection Man by Charlotte MacLeod

Boston-based art detectives Sarah Kelling and husband Max Bittersohn were hoping for some time off after their last case, especially since Max is still recovering from a broken leg he suffered during the investigation. That hope dies quickly, though, when they run into Countess Lydia Ouspenska.

The Countess, an expert forger of Byzantine icons, tells them that an old acquaintance, Bartolo Arbalest -- known in their circles as "The Resurrection Man" because of his skills in restoring damaged works of art -- has set up a Renaissance-style "guild" in their fair city, with a number of artisans working independently under one roof. Nothing mysterious about that, of course -- except for the fact that some of Boston's wealthiest citizens have been murdered shortly after valuable objets d'arts restored by Arbalest's organization were returned to them.
