Child's Play

A Dalziel and Pascoe novel. Only one thing seems certain to those mentioned in Gwendoline Huby's will: the main beneficiary won't collect as he's been dead for forty years. Or has he? At the funeral an unknown mourner advances and hurls earth into her grave and cries "Mama!". The son reported killed in wartime Italy or an imposter? Time--and murder-would soon tell.
