"Yes, we'll go with you," said Ned.
"No, you stay here," Jack insisted. "One of us won't be noticed. Three would. Besides, that house is full of other tenants. Nothing much could happen to me."
In spite of their further protests he walked rapidly, but cautiously, down the alley-way. Noiselessly he entered the hallway and walked to the door of a rear room, where he heard voices. But it was a laboring man and his wife quarreling over something. Jack heard a door open on an upper floor. Then came a voice that thrilled him. It was Jarrow's.
"Hullo, Judson, back again? Well, how did things go?"
Then Jack heard the door closed and locked.
"So, they are really here," he muttered. "What a piece of luck. But the question is, have they got the code? If it is out of their hands it will be well nigh impossible to recover it, for it is a serious matter to charge an ambassador with wrong-doing."
Jack began to ascend the rickety stairs with great caution. They creaked dismally under his tread. At a door on the second floor he caught the sound of Judson's voice. With a beating heart he crept as close as he dared and listened.
"The plans have all been changed," he heard Judson saying. "We are to take the code to Crotona (the capital of the power represented by the ambassador) ourselves. There's a steamer that leaves Baltimore for Naples to-morrow. We are to take that and proceed from Naples to our destination."
"What a bother," came in Donald's voice. "I don't see why the ambassador didn't take them."
"He said it was too dangerous. He was being watched by the Secret Service men."
