A Place of Execution by Val McDermid

Now this one I enjoyed. From page 227 of the mass market paperback edition (my new favorite insult):

Who spared that would drown nothing.

Also, instead of saying "as soon as I laid eyes on her" one of the characters says "as soon as I clapped eyes on her," which I love.

From the back cover:

Winter 1963: two children have disappeared off the streets of Manchester; the murderous careers of Myra Hindley and Ian Brady have begun. On a freezing day in December, another child goes missing: thirteen-year-old Alison Carter vanishes from the isolated Derbyshire hamlet of Scardale, a self-contained, insular community that distrusts the outside world. For the young George Bennett, a newly promoted inspector, it is the beginning of his most difficult and harrowing case: a murder with no body, an investigation with more dead ends and closed faces than he'd have found in the anonymity of the inner city, an outcome which reverberates down the years. Decades later he finally tells his story to journalist Catherine Heathcote, but just when the book is poised for publication, Bennett unaccountably tries to pull the plug. He has new information which he refuses to divulge, and which threatens the very foundations of his existence. Catherine is forced to reinvestigate the past, with results that turn the world upside down.
