After some recovery time for the Conviction Review Unit, Elke Lawrence is ready for a challenge.

But she gets more than she bargained for with this new case, involving a man convicted of killing his wife sixteen years before. There's no body. No murder weapon. No physical evidence at all except two small drops of blood in his kitchen. The DNA of the blood doesn't match anyone involved in the case.

There's challenging, and then there's impossible.

Elke is beginning to think this case is the latter.
