At a narrow opening Buck turned and left the main street. Fifty yards along the side street he stopped the rickshaw and paid off the coolie, each taking his own kit-bag. Next Buck plunged into a dusky, ill-lighted alley, and Jack followed, wondering.

"I'm making for a friend's house," murmured Buck, "an' I'm takin' a shy road. We've got to keep our eyes skinned from now on."

"Do you think the gang will be on the look-out for us in Rangoon, Buck?" asked Jack.

"Likely enough," replied Risley. "No harm in takin' care, anyway."

The two gained a narrow lane beyond the alley, followed it some distance, then turned into a wider street. Here Buck paused before a shop whose windows were closed, but rays of light were streaming through chinks in the shutters. He tried the door and found that it was not fastened.

"Nip right in," said Risley, and the two entered briskly, and closed the door behind them. Behind the counter stood a tall, elderly man taking a rifle to pieces by the light of a brightly-burning lamp. He was surrounded by weapons of all kinds, and a single glance told Jack that he stood in a gunsmith's shop.

"Hello, Buck," said the tall man calmly. "Slidin' in like a thief in the night, eh? What's wrong, and who's your friend?"

"This is the Professor's son, Mr. Jack Haydon," replied Buck, answering the last question first, as he put down his bag and shook hands with his acquaintance.

"Pleased to know you, sir," said the gunsmith, offering his hand to Jack in turn. "Me and your father have known each other a long time and done a lot of business together. Perhaps you've heard him mention me, Jim Dent?"

"Yes, Mr. Dent," said Jack, "I've heard your name many a time."
