What's scarier? An ax murderer or a family Christmas?

Mom wants to make the most of Christmas in Montana. I want to catch a killer.

Surprisingly, my girlfriend meeting my family isn't the worst thing to happen. Turns out killers don't take off the holidays.

If I can solve this murder quickly, I can guarantee all the killer gets for Christmas is a pair of handcuffs and a jail cell.

Is that too big of a Christmas miracle?
