Water Like a Stone by Deborah Crombie

I always eagerly await the next Deborah Crombie novel. Her book, Dreaming of the Bones, is one of my favorite mysteries ever. In the latest in the series, Gemma James (London Metropolitan Police) and Duncan Kincaid (New Scotland Yard), travel with their sons Kit and Toby to Duncan's parents in Cheshire for Christmas. Soon after they arrive, Duncan's sister, Juliet, finds a mummified infant's body in the wall of a building she's rehabbing. Family tensions are high because of the unravelling of Juliet's marriage and the unhappiness of her teenage daughter, Lally. The mystery deepens as we meet the boat dwellers who live along the historic canals near Nantwich. Regular readers of the series might be surprised that Gemma and Duncan are not the main detectives in the book, but the book was still satisfying. For people who enjoy Peter Robinson and Ruth Rendell's Inspector Wexford.
