three o'clock sharp
The rest was easy enough . A couple more walked in after , and while one jumped over the counter and bailed up the manager the other shut the door . Nothing strange about that . The door was always shut at three o'clock sharp . Nobody in town would drop to what might be going on inside till the whole thing was over , and the swag ready to be popped into a light trap and cleared off with . That was the idea . We had plenty of time to think it over and settle it all , bit by bit , beforehand .
