Mike opened the door again, hiding his figure behind it for protection as it swung out. I expected to see some one shot, but Moore threw the light in, and instantly Oakes dived forward into the alcove of stone. We could hear him chuckle. Cook, at my side, was standing on one leg in his excitement. Then Dr. Moore burst into laughter.
"What is it? What's the matter?" I cried. I could not see very well, and ran half-way down. Oakes was standing beside Moore, trying to look grave. In his hand was a red paper mask and a long black robe!
O'Brien looked on, his eyes twinkling, but his face serious. "I'm thinking it's lucky, Mr. Clark, sorr, that ye saved yer ammunition," said he.
"Yes," retorted Oakes, "and it's still more fortunate you're a good actor."
O'Brien's somewhat insolent manner changed instantly to one of civility, and Oakes turned to us.
"No wonder some said there was a woman in this affair."
Then he ordered the hatch door nailed down, and handed the things to me. "Please take these upstairs, Stone; we must investigate this more fully," and we withdrew to discuss our findings.
"What do you think of O'Brien, Oakes?" I asked. "He seems to be a cool sort of a customer."
"Yes, he is no ignoramus. He's a shrewd fellow, and a deep one; but I have learned a few things."
