a match and puffed out several clouds of smoke. Then he tossed the match into the fire, and nodded through the tobacco clouds. "I agree with you, Jack," he said. "This is the queerest thing I ever came across in my life. I've known Tom Haydon, boy and man, this forty-five years, and he's as straight as a gun-barrel. If they expected him back at that hotel, if Risley expected him back, then he meant to come back. And if he didn't get back, it was because he was interfered with. I'd stake a hand on that."

Jack nodded with glistening eyes. "And I'm going to see why he didn't come back," said the lad.

"I'd come with you if I could," said Mr. Buxton, "but at present I can no more leave London than the Monument can. I'm as fast by the leg, held by press of work, as a bear tethered to a stump. How do you stand for funds?"

"I've only got a sovereign or two in my pocket," said Jack. "I was depending on you."

"Yes, yes," said Mr. Buxton, "of course you were. I made time an hour or so ago to run over your father's accounts. There's plenty to draw on." He went over to his desk and ran his fingers through a bundle of papers. "Here it is," he remarked. "At the present moment your father is worth the respectable sum of forty-seven thousand two hundred and nineteen pounds eighteen shillings and fourpence; so he certainly hasn't run away from his creditors."

Jack nodded. "I'll start straight for Brindisi to-night, Mr. Buxton. I can't lose a minute till I get on to the spot and talk with Buck Risley."

Mr. Buxton nodded. "I quite understand your feelings, Jack," he replied. "I've wondered whether the matter might not have a very simple explanation after all. One thing struck me. Has your father ever said anything about his health to you? You know he's been a great deal in India and Burmah. It's a very easy thing to get a touch of the sun, and that will often cause a man to lose the sense of his identity and get lost for a time."

Jack shook his head. "I've never heard him mention such a thing," he said. "He's always been perfectly fit whenever I've seen him."

"Yes, yes," said Mr. Buxton, "and whenever I've seen him, too. He has a wonderful constitution. But, you know, the possibility crossed my mind, and I mentioned it."

At this moment the servant announced that the meal was ready, and Jack did his best to eat something. It was a very poor best, however, for he was too anxious to be on his way to be able to eat, and he was relieved when Mr. Buxton said it was time to start and sent the servant for a cab.

On their way to Charing Cross they did not talk much: conjecture was a pretty useless thing, and, in their present state of utter lack of information, conjecture was the only thing possible.

The bustle of getting a ticket and finding a seat occupied most of the ten minutes they had to spare before the train started, and, as the swift express glided out, Mr. Buxton waved his hat to Jack leaning through the window, and cried, "Good luck!"

Of Jack's swift scurry across the Channel and over the Continent it is not necessary to enter into details. He made the journey with the utmost speed, and chafed at every delay. At last the train ran into the station of Brindisi, and Jack hung half out of the window, his eyes searching the crowd for Risley, to whom he had telegraphed his time of arrival.

"Hullo, Buck," sang out Jack, as a middle-sized, stiff-built man of five and thirty ran up to his carriage door.

"Glad to see you, Jack," said Buck Risley, as they shook hands. "Very glad to see you."

"Any news?" snapped Jack.

"Not a word," replied Buck gravely, "not a word. Is this your bag?"

"Yes," said Jack sombrely, for he was very disappointed. He had been hoping to hear that something had been found out, or that his father had returned.

Buck took Jack's gladstone, called a carriage, and gave the name of the hotel. He did not speak till they were rattling along the streets of Brindisi.

"Say, Jack, this beats the band," he said. "I can't make a guess what's happened to the Professor."

Mr. Haydon and Buck Risley had first met in a "wild-cat" mining camp in Dakota. The Lone Wolf Clarion had introduced the English engineer to the local community as Professor Haydon, and Mr. Haydon had been the Professor ever since to his part-comrade, part-servant.

"Tell me all about it," said Jack, and Buck began his story. It was soon finished, for there was very little to tell. They had been four months in Burmah, and Mr. Haydon and Buck had gone up to Mandalay, and then on to the Mogok country. At Mogok Buck had been seized with a sharp touch of fever, and had been compelled to remain in that famous mining town while Mr. Haydon went up country, accompanied only by a few natives who had been with him in other journeys. He came back after an absence of five weeks to Mogok, found Buck better, and announced that they would return to England at once. They had packed and started forthwith, and returned by the usual route.

"Did my father seem quite himself, just as usual in every way, Buck?" asked Jack.

"No," said Buck thoughtfully. "He didn't quite. There was somethin' on the Professor's mind, I'm sure o' that."

Jack put forward Mr. Buxton's suggestion, but Buck waved it aside.

"Touch o' the sun," said he. "Oh, no, nothin' like that. The Professor was as fit as he always was, right as a bull-frog in a swamp. No, it was a sort of anxiousness there was about him. He was that careful that you might almost call him fidgetty."

"Fidgetty!" said Jack in surprise, as he remembered the perfectly equable manner of his widely-travelled father.

"Yes, that's as good a word as any I can jump on at short notice," replied Buck. "He seemed as keen on getting back to London as some o' these globetrotters who have got sick o' foreign parts."

"That was rather strange," commented Jack. "You've been with my father twelve years now, Buck. Did you ever see him like it before?"

"Never in my knowledge of him," said Buck, shaking his head. "As a general rule the Professor was as calm an' easy campin' in a jungle as another man in a front seat at a circus. It was all one to the Professor, let things come how they might. But this time he seemed as if his only idea was to get back. Not that he said much about it. The most I ever heard him say was, 'Well, Buck, I don't care how soon I get into Lane & Baumann's office,' an' he only said that once when he was fretted at losing a day by missing a boat at Rangoon."

At this moment the carriage drew up at the door of the hotel. They had scarcely entered the door when the hotel clerk came forward with a cablegram. It was from Messrs Lane & Baumann, asking if anything was yet known of Mr. Haydon.

"If he was anxious to see them, they are just as anxious to see him," said Buck, handing the form to Jack. "Every day they wire, an' sometimes twice a day, to know if I've got hold of any news."

"I wish I'd been to see them before I left London," said Jack. "I might have got some useful information from them. What do you believe has happened to my father?"

"I dunno what to think," said Risley, "except that some o' these Dagoes got him in a corner and went for his pocket-book. He'd got plenty of money with him."

"But if he'd been attacked by thieves," argued Jack, "the police would have found something out before this. He could not have been hidden away from them."

Buck shook his head. "Some o' these Dagoes are very sly and deep," he replied. "I've heard queer stories about 'em at times. They say there are brigands around."

"Yes, yes," said Jack, "in Sicily and in some of the wilder parts of Calabria, but not in Brindisi, Buck, not in this
