An interesting drink

Moody was sitting in a dark corner of the room, drinking from his flask...Tom was already used to Moody's odd drinking habits, and after Moody got into the habit of paying for a closed bottle of Brandy or Firewhiskey he learned never to disturb Moody once he had bought his bottle and taken his seat...This time he was sitting and just watching the people entering and leaving, his back to the wall, a good view of the fireplace and as well as the doors. Though his eye would do the work for him...always paid to be too careful.
