Lying in Wait by Liz Nugent
My husband did not mean to kill Annie Doyle, but the lying tramp deserved it.
On the surface, Lydia Fitzsimons's life seems idyllic. Her husband, Andrew, is a prosperous, respected judge; they live in the spacious, comfortable, well-appointed house where she was raised. And she is utterly, obsessively devoted to her son, Laurence—her adored only child, her pride and joy.
But Andrew's murder of Annie Doyle, accidental or not, sets into motion a dark downward spiral. It doesn’t take long for Laurence to suspect that something is very, very wrong in the Fitzsimons household—and he is determined to discover the truth.
