The man left the house immediately. Blair Windsor arrived, carrying two automatics and a flashlight. He showed the cartridges in the dim light, and pressed one of the revolvers into Harry’s hand.
“Now for the cellar,” he whispered. “You’ll have to show me what happened.”
In the cellar, Harry explained the circumstances. The two men went to the corner where the shelves were located.
“This is the spot,” said Harry.
“Let’s pull at those shelves,” suggested Blair. “This corner is directly toward the hill. I’ll bet there’s a passage here.”
He pushed and tugged at different shelves, but with no success. Harry joined in the work.
As Blair Windsor stepped away, Harry suddenly obtained results. The whole section of shelves swung into the cellar, as though hinged. The flashlight showed a low, dark tunnel into the hillside.
“What about it?” questioned Harry. “Shall we go in? Or shall we wait?”
Blair hesitated. He paused, perplexed. He examined the shelves, and assured himself that they were loose. There was no danger of being trapped.
“We shouldn’t separate,” he said, quietly. “Better to stay together. I’ll go first, Harry. You follow. We’ll investigate and then return. If we run into trouble, use your gun.”
