On the afternoon of the second day Jack announced his decision. "Buck," said he, "I'm going back to London. I want to see Lane & Baumann. It's quite possible that some information may be gleaned from them which would give us a basis to go to work upon."
"It's no good stopping here," said Risley. "When shall we start?"
"To-night," said Jack, and, being near the station, they turned in to look up the time of the fast express. Jack glanced along the platform, and soon found what he sought, one of Cook's interpreters. "I want to ask some questions of the booking-clerk," he said to the man, slipping several lire into his hand, "you might come and interpret for me."
"Yes, sir," said the man at once, and followed the tall young Englishman to the office. In three minutes Jack had learned what he wished as to the shortest route and fastest trains; then he and Risley set out to return to the hotel. Suddenly Jack remembered another point, and crying, "Half-a-minute, Buck," he rushed back to the office. He thrust open a swing door and saw that the interpreter was still there, and was now in conversation with a smaller man. Jack stepped forward, and the smaller man looked up and gave a short, quick cry of alarm. For a second Jack stood with widely-opened eyes and parted lips, an image of wild surprise. Then darting forward at full speed, he seized the second man by the throat, and clutched him as a lion clutches his prey.
CHAPTER III.
THE BIG RUBY.
Jack had known the fellow at once, had recognised him instantly as the small, dark man who had stood in front of him upon Rushmere Heath and demanded that he should produce his father's letter. An instant conviction had darted into Jack's mind that these things were connected, and that this man knew something of his father's disappearance.
"I've got you this time," cried Jack, and was upon him in a second. But a most astonishing thing happened. The small, slight man offered no resistance to Jack's fierce rush, instead, he seemed to give way before it as a reed gives way before the wind. Then he bent slightly and laid one small, sinewy hand on Jack's knee, and, in some mysterious fashion or another, the lad felt that his hold was torn away, and that he was flying through the air over the little man's head. All in a heap Jack landed on the dusty floor. As he fell, he caught a glimpse of Buck's head thrust through the swinging door as he followed his young leader, and saw the look of surprise on Buck's face.
