The Murder Rule by Dervla McTiernan
Law student Hannah Rokeby is desperate to become a volunteer for the University of Virginia’s Innocence Project. So, to gain a place, she threatens its head professor with blackmail. More intrigued than threatened, the professor interviews and accepts her conditionally, even with his reservations. But why would this volunteer position be so important to this transfer student from Maine? This is a twisty, original, enjoyable mystery.
