On A Killer's Trail — Susan Page Davis

A sweet, elderly lady is killed on Christmas Day, and nothing else--not a single wrapped gift around the tree--is disturbed. Detective Neil Alexander can't figure out the motive. Rookie reporter Kate Richards wants the story, but Neil has little to share. Until there's another murder. Same M.O. Same ballistics. There has to be a connection. And Kate is determined to find it. Neil is impressed with her dedication, but he worries about where it will lead. They're on a killer's trail. And keeping Kate safe means keeping his heart off-limits.
