Unnatural Murder - Paperback

Sebastian Acosta has been gunned down at three AM on a Saturday morning, sitting behind the wheel of a beaten up Toyota. The passenger door is open and a few paces away his pal, Luis Irizarry, lies with his life ebbing away through two gunshot wound in his chest. It should be a red hot case, except that fifteen years earlier, Rosario Rojas was raped and strangled in that self same house, the house Luis was crawling toward, the house that belonged to Angela Rojas, Rosario's daughter.

Rosario, who was like a sister to Marta Flores, Detective Dehan's mother.

Things get more complicated when it emerges that Rosario had started to get involved in a set whose morals Marta had considered a little too lax, a bit too broad-minded; when it emerges that the two boys who just got shot are the sons of two of the couples that made up that set.

But then it turns out, this is just the tip of the iceberg, in this old, cold case...
