"In that case keep him in sight and communicate with me, or with the police. I shall stay here for a little while. Then I shall get the hall-porter (if you will instruct him before you go) to show me the ladder and the vicinity of Dowden's operations. Also, I think I shall look at the back staircase."
"But that was found locked, with the key inside."
"Well, well, there are ways of managing that, as you would know if you knew as much about housebreaking as I do. But we'll see."

Mr. Colson took a cab for Kanamaro's lodgings. Kanamaro was not in, he found, and he had given notice to leave his rooms. The servant at the door thought that he was going abroad, since his boxes were being packed, apparently for that purpose. The servant did not know at what time he would be back.
Mr. Colson thought for a moment of reporting these facts at once to Dorrington, but on second thoughts he determined to hurry to the City and make inquiry at some of the shipping offices as to the vessels soon to leave for Japan. On the way, however, he bethought him to buy a shipping paper and gather his information from that. He found what he wanted from the paper, but he kept the cab on its way, for he happened to know a man in authority at the Anglo-Malay Company's office, and it might be a good thing to take a look at their passenger list. Their next ship for Yokohama was to sail in a few days.
But he found it unnecessary to see the passenger list. As he entered one of the row of swing doors which gave access to the large general and inquiry office of the steamship company, he perceived Keigo Kanamaro leaving by another. Kanamaro had not seen him. Mr. Colson hesitated for a moment, and then turned and followed him.
And now Mr. Colson became suddenly seized with a burning fancy to play the subtle detective on his own account. Plainly Kanamaro feared nothing, walking about thus openly, and taking his passage for Japan at the chief office of the first line of steamships that anybody would think of who contemplated a voyage to Japan, instead of leaving the country, as he might have done, by some indirect route, and shipping for Japan from a foreign port. Doubtless, he still supposed that nobody knew of his errand in search of his father's sword. Mr. Colson quickened his pace and came up beside the Japanese.
Kanamaro was a well-made man of some five feet eight or nine—remarkably tall for a native of Dai Nippon. His cheek-bones had not the prominence noticeable in the Japanese of the lower classes, and his pale oval face and aquiline nose gave token of high sikozu family. His hair only was of the coarse black that is seen on the heads of all Japanese. He perceived Mr. Colson, and stopped at once with a grave bow.
"Good morning," Mr. Colson said. "I saw you leaving the steamship office, and wondered whether or not you were going to leave us."
