My horror plot

Twelve

A bunch of friends go camping on new years eve. They go to a semi desolate wooded area by a farm. When collecting wood to create a fire they hear freaky noises which makes them uneasy, like they were being watched.  They get more and more drunk as the night draws in, and start talking about the guy who owns the farm, telling stories and myths. As the night progresses they become a bit of a menace, they're vocal and create alot of mess. Suddenly from the darkness a man appears, small, scruffy but intimidating and very aggressive. Yelling that they've ruined his crops and comes at them, one friend has a go back at the farmer, and aggrivates him more. They grab a log from the fire and burn his face, while another knocks him cold when they see him reach for a gun from within his pocket. The main protagonist (Tuesday) shakily picks it up from the ground and keeps a tight hold of it. Eventually everyone seems to settle a bit around by the fire which is now dying down, a few continue to drink. The farmer gets up without them noticing and pulls a knife from his breast pocket, lunging for them, Tuesday picks up the gun and shoots and kills him at exactly 12. As everyone stands there in shock fireworks go off in the background, the start to the new year.
They return home new years day, quite and visably shaken, blaming it on vast alcohol cunsumption to everyone else and attempt to carry on. On the 12th of January Tuesday recieves an anomous  letter in the post with single letter in what looks like red paint, she puts it to one side and tries to carry on. On the last day of January a friend dies mysteriously at exactly midnight.
