Lying In Wait by Liz Nugent

The last people who expect to be meeting with a drug-addicted prostitute are a respected judge and his reclusive wife. And they certainly don’t plan to kill her and bury her in their exquisite suburban garden. Yet Andrew and Lydia Fitzsimons find themselves in this unfortunate situation. While Lydia does all she can to protect their innocent son Laurence and their social standing, her husband begins to fall apart. But Laurence is not as naive as Lydia thinks. And his obsession with the dead girl’s family may be the undoing of his own.
