"I don't understand what his share in the plot is, or has been," Ned had explained, "but it is evident that he will be needed only as a witness."
At Manila Ned had held a long conference with Major John Ross, and that gentleman had seemed overjoyed at the report the boy had presented, especially as it made his return to the group of islands to the north unnecessary. After remaining in Manila one day and a night, Ned had been directed to continue his investigation of the case in his own way.
To tell the truth, Major John Ross and the military men with whom Ned conferred at Manila treated the employment of the boy by the authorities at Washington as a good deal of a joke, as a whim. They were not discourteous to Ned, but they took no interest in his suggestions. For some hours after his departure, his employment on the case was the subject of many sarcastic remarks.
However, those in charge had consented to hold the Manhattan subject to his orders, and had promised to give any communications received from him due attention. And this was the situation when the boy, following clues secured at the nipa hut and hints obtained from Pat, who had kept his ears open during his captivity, and from French, had sailed away for Japan with his chums on a steamer which was leaving Manila for Yokohama. Pat Mack, released from service by the effort of Major Ross, at his own request, had been left at Manila in charge of the Manhattan.
The boys landed shortly after dark and proceeded to a hotel where the English language or something like it was spoken. Everything was new and strange, the place being as unlike a Broadway hotel as it is possible to imagine. However, the meals were served in half-American fashion, and the rooms were tolerably comfortable.
"Now," Ned said, after their first meal in Yokohama was over, "we did not come here to visit the palaces of the wealthy, or to inspect the United States consulate. We've got to get down into the slums a bit if we find what I want. The man who led the party that captured Lieutenant Rowe was sent away as soon as he got to his masters. You doubtless understand why. They did not want him implicated in the plot."
"How do you know?" asked Jimmie. "You didn't see him go, did you?"
"Then he must be up some," Jack said.
"And he left Manila on a boat bound for Yokohama," Frank added. "I know about that, for French gave me a valuable tip. And he was accompanied by an American sailor with a thirst for strong drink."
"I guess you've got the idea, all right," Ned said, with a smile. "But I did not state the case exactly as it is. I said that the man who led the party against Lieutenant Rowe was sent away. I should have said that the man suspected of having been at the head of that expedition had mysteriously disappeared from Manila on the very day of his return there after an absence unaccounted for, and that it was believed he had taken a steamer for Yokohama. I stated my conclusions as facts."
