Darkness & Light by John Harvey

This mystery novel is part of Frank Elder series, set in modern day England.  This is the first one I've read, but several have preceded this one.  In this story, Frank, now retired, is called on by his ex-wife to help look into the disappearance of a friend's sister.  Of course, it turns out to be murder, and with connections to an unsolved case from Frank's past.  Stylishly written, there are enough plot twists to keep it moving briskly along, but the conclusion is not all that surprising.  The parts about Frank coming to terms with reconnecting with his family are less successful, but I think I'll try to find some of the earlier books in the series. 350 pages
