Never Tell - Lisa Gardner

One death might be an accident. Two deaths looks like murder. A man is shot dead in his own home, and his pregnant wife, Evie, is found with the gun in her hands. Detective D.D. Warren instantly recognises her. Sixteen years ago, Evie also shot her own father. That killing was ruled an accident. D.D. doesn’t believe in coincidences. But this case isn’t as open and shut as it first appears, and her job is to discover the truth. Evie might be a victim. Or she might be about to get away with murder again.
