As I see the letters on my desk I am prepared for the normal weird Christmas problems that come every year. Flying reindeer sightings and that is obviously the real Santa. That is until I see the familiar vellum envelope addressed directly to me. Hand delivered as always by a random person, always different people. I turn it over to see the dread filled wax seal with the same imprint, a c that's in flames. I call over my superior as I always needed a witness last time so better start on the right foot with this one. I open the letter written on thick ancient paper and read aloud. 

"To my friend," they always started this way.

"On the first day of Christmas my friend couldn't stop me, from destroying an enemy." 

My heart sinks as I read these words. I thought i had put this case to bed 5 years ago. But no of course not. Something always felt wrong about the arrest that was made but no one would listen to me and now they are back and have probably already done it again. The Christmas killer is back, and I won't make the same mistake again.
