“Who’s there?” called a voice.
“What do you want to give that name for? Haven’t you got another?” asked the voice, anxiously.
Nick saw that Gillman was very suspicious.
He felt, too, that he must act quickly. He had already guessed that Yasmar’s true name was Ramsay, but had never verified it. Now he was face to face with the question.
He took a long chance, and called out:
“Ramsay.”
To his delight he heard the bolts being drawn back, and the door was thrown open.
“You know, Ram——” Gillman began, then he stopped dead, for the man who had entered was not Ramsay, but Nick Carter.
Without taking his eyes off Gillman, Nick closed the door and locked it.
