Child's Play (Dalziel and Pascoe Series #9)

There shouldn't be anything unusual about the death of an elderly widow, until a man appears at her graveside, claiming to be her long-lost son. He's entitled to shed all the tears he likes, but whether he's entitled to her substantial fortune is another question. It's a poser, but one Fat Andy can handle much more easily than he can the decision of the resolutely boring Sgt. Wield to come busting out of the closet.
