Necessary As Blood is the latest entry in Deborah Crombie’s New York Times Notable, Edgar®, Agatha, and Macavity Awards-nominated mystery series featuring Scotland Yard detectives Duncan Kincaid and Gemma James. A Texan frequently compared to the masters of British crime fiction—including P.D. James, Martha Grimes, Barbara Vine, and fellow American Elizabeth George—Crombie dazzles once more with Necessary As Blood —a relentlessly suspenseful tale of a vanished mother, a murdered father, and a helpless, endangered child.
