Charlie and Ron are hired by a retired Seattle homicide detective to handle the local portion of his current investigation. It was a case where he failed to find the bodies of two missing children. Their Mother was found innocent in her trail. She than disappeared and the detective wants to located her. He feels the Mother is settled in New Mexico as her family is living there. This set against a Christmas celebration and unusual snow storm. The story was very good but I recognize the answer very early in the story.
