Lieutenant Eve Dallas has plenty to be grateful for this season. Hosting Roarke's big Irish family for the holiday may be challenging, but it's a joyful improvement on her own dark childhood. Other couples aren't as lucky as Eve and Roarke. The Reinholds, for example, are lying in their home stabbed and bludgeoned almost beyond recognition. Those who knew them are stunned, and heartbroken by the evidence that they were murdered by their own son.
