Never Tell a Lie by Hallie Ephron

Ivy Rose and her husband, David, are awaiting the birth of their first child when they decide to hold a garage sale to get rid of the stuff the previous owner of their Victorian home left behind. Ivy is surprised when Melinda White, a high-school classmate (and whom she hasn't seen since then) shows up. Melinda is pregnant, too, and David (who also went to school with them) agrees to show Melinda the inside of their home, since Melinda knew the former owner. Soon, however, the police are questioning the Roses. It seems that, after going into the house with David, Melinda was never seen again. The pressure on Ivy is unbearable, since the police consider David their prime suspect. Naturally, it is compounded by her being nine months pregnant. Soon, evidence begins piling up. Ivy wonders how much she can rely on David and who possibly is out to ruin their lives. Never Tell a Lie is a page turner that fans of Mary Higgins Clark will enjoy. While not as complex storywise and in character development as the novels of Harlan Coben, his readers who don't mind a female protagonist might like this also.
