"That's two men's work," Dakota exclaimed.
"Three—at least," corrected Cockney thoughtfully, "two to lift the gate, the third to remove the chain."
Dakota looked fearfully about in the dim moonlight.
"Then—then there's a gang about!" he whispered.
"Come back to the house," said Cockney. "It's worth looking into."
Beneath Professor Bulkeley's window he stopped and called his name. Mary Aikens came timidly from the house, a lonely little figure bathed in the moonlight.
"What is it, Jim?"
He turned on her roughly.
"Go inside. This at least is no concern of yours."
She obeyed without a murmur, her feet dragging forlornly over the frosty grass.
