For an instant Trevison regretted that he had not taken Levins' advice about forming a posse of his own men to take the courthouse by storm, and he debated the thought of postponing action. But there was no telling what might happen during an interval of delay. In his rage over the discovery of the trick that had been played on him Corrigan might tear the interior of the building to pieces. He would be sure to if he suspected the presence of the original record. Trevison did not go for the help that would have been very welcome. Instead, he spent some time twirling the cylinder of his pistol. He grew tired of crouching after a time and lay flat on his stomach in the shadow of the tool shed, watching the men as they tramped back and forth, around the building. He knew that sooner or later there would be a minute or two of relaxation, and of this he had determined to take advantage. But it was not until sound in the town had perceptibly decreased in volume that there was any sign of the men relaxing their vigil. And then he noted them congregating at the front of the building. "Hell," he heard one of them say; "what's the use of hittin' that trail _all_ night! Bill's inside, an' we can see the door from here. I'm due for a smoke an' a palaver!" Matches flared up; the sounds of their voices reached Trevison. Trevison disappointedly relaxed. Then, filled with a sudden decision, he slipped around the back of the tool shed and stole toward the rear of the courthouse. It projected beyond the rear of the bank building, adjoining it, forming an L, into the shadow of which Trevison slipped. He stood there for an instant, breathing rapidly, undecided. The darkness in the shadow was intense, and he was forced to feel his way along the wall for fear of stumbling. He was leaning heavily on his hands, trusting to them rather than to his footing, when the wall seemed to give way under them and he fell forward, striking on his hands and knees. Fortunately, he had made no sound in falling, and he remained in the kneeling position until he got an idea of what had happened. He had fallen across the threshold of a doorway. The door had been unfastened and the pressure of his hands had forced it inward. It was the rear door of the bank building. He looked inward, wondering at Braman's carelessness--and stared fixedly straight into a beam of light that shone through a wedge-shaped crevice between two boards in the partition that separated the buildings.
