The cradle in the grave

 by Sophie Hannah. Hannah, author of masterfully crafted psychological thrillers, this time spins a complex tale centered on a controversial social issue. Imprisoned for killing her two sons and forced to give up her infant daughter, Helen Yardley was pardoned years later after expert testimony at her trial was challenged. Finally free, she is promptly murdered. Although filmmaker Fliss Benson wants nothing to do with the Yardley case, her boss assigns her to complete a documentary on wrongly-accused mothers, including Yardley. Her interest is piqued, however, after she receives an anonymous card with a grid of 16 numbers that is just like the one left on Yardley's body. Investigating officer DC Simon Waterhouse, chafing against his hated superior, who worked the original Yardley case, involves his fiancee, DS Charlie Zailer, and the two find themselves seeking not only the murderer but also the truth about the charges against Yardley and another mother accused of murder. The quirks of the Waterhouse-Zailer relationship add interest and even some comic relief from the pain portrayed in this compelling novel. --Booklist (Check Catalog)
