When detective Leo Junker receives an envelope containing a photo of a woman murdered five years previously, he knows that this is no ordinary case.

But perhaps the two incidents aren't unconnected . . .
As Leo begins to investigate, familiar faces re-appear and he is forced to confront the past he thought he had left behind.
