Water Like a Stone (Duncan Kincaid/Gemma James Novels, 11)

Detective Superintendent Duncan Kincaid and his partner, Sergeant Gemma James, take their sons to picturesque Cheshire for their first family Christmas with Duncan's parents—a holiday both dreaded and anticipated. But not even the charming town of Nantwich and the dreaming canals can mask the tensions in Duncan's family, which are tragically heightened by the discovery of an infant's body hidden in the wall of an old dairy.
As Duncan and Gemma help the police investigate the infant's death, another murder strikes closer to home, revealing that far from being idyllic, Duncan's childhood paradise holds dark and deadly secrets . . . secrets that threaten everything and everyone Duncan and Gemma hold most dear.
