"Put out that lamp," he exclaimed, but before she could move he was past her and had blown out the flame.
"Fred! What is it?" she asked in an agitated whisper.
"Silence," he said fiercely, as he crept back to the window and stooped to peer into the night.
Along the fence which formed the boundary of the bank's ground, the fence Durham had pointed out as the one over which Eustace must have made his escape, he saw the figure of a man stealthily creeping.
He thrust his hand into the pocket where he had slipped the revolver Brennan had given him.
"Fred! Fred! What do you see?" he heard Mrs. Eustace whisper, and in the dim obscurity he saw her come to his side.
"Quiet," he said harshly.
Both her hands, trembling, touched his arm.
"Tell me," she whispered; "I will be brave. Who is it you see?"
The thin streak of moonlight falling through the narrow space between the blind and the window glinted on the bright barrel of the revolver, as he drew it from his pocket.
