Mr. Robert Stobell, whose work as a contractor had left a permanent and unmistakable mark upon Binchester, became imbued with a hazy idea that Mr. Chalk had invented a new process of making large diamonds. Mr. Jasper Tredgold, on the other hand, arrived at the conclusion that a highly respectable burglar was offering for some reason to share his loot with him. A conversation between Messrs. Stobell and Tredgold in the High Street only made matters more complicated.
"Chalk always was fond of making mysteries of things," complained Mr. Tredgold.
Mr. Stobell, whose habit was taciturn and ruminative, fixed his dull brown eyes on the ground and thought it over. "I believe it's all my eye and Betty Martin," he said, at length, quoting a saying which had been used in his family as an expression of disbelief since the time of his great-grandmother.
"He comes in to see me when I'm hard at work and drops hints," pursued his friend. "When I stop to pick'em up, out he goes. Yesterday he came in and asked me what I thought of a man who wouldn't break his word for half a million. Half a million, mind you! I just asked him who it was, and out he went again. He pops in and out of my office like a figure on a cuckoo-clock."
Mr. Stobell relapsed into thought again, but no gleam of expression disturbed the lines of his heavy face; Mr. Tredgold, whose sharp, alert features bred more confidence in his own clients than those of other people, waited impatiently.
"He knows something that we don't," said Mr. Stobell, at last; "that's what it is."
Mr. Tredgold, who was too used to his friend's mental processes to quarrel with them, assented.
"He's coming round to smoke a pipe with me to-morrow night," he said, briskly, as he turned to cross the road to his office. "You come too, and we'll get it out of him. If Chalk can keep a secret he has altered, that's all I can say."
His estimate of Mr. Chalk proved correct. With Mr. Tredgold acting as cross-examining counsel and Mr. Stobell enacting the part of a partial and overbearing judge, Mr. Chalk, after a display of fortitude which surprised himself almost as much as it irritated his friends, parted with his news and sat smiling with gratification at their growing excitement.
"Half a million, and he won't go for it?" ejaculated Mr. Tredgold. "The man must be mad."
"No; he passed his word and he won't break it," said Mr. Chalk. "The captain's word is his bond, and I honour him for it. I can quite understand it."
Mr. Tredgold shrugged his shoulders and glanced at Mr. Stobell; that gentleman, after due deliberation, gave an assenting nod.
"He can't get at it, that's the long and short of it," said Mr. Tredgold, after a pause. "He had to leave it behind when he was rescued, or else risk losing it by telling the men who rescued him about it, and he's had no opportunity since. It wants money to take a ship out there and get it, and he doesn't see his way quite clear. He'll have it fast enough when he gets a chance. If not, why did he make that map?"
Mr. Chalk shook his head, and remarked mysteriously that the captain had his reasons. Mr. Tredgold relapsed into silence, and for some time the only sound audible came from a briar-pipe which Mr. Stobell ought to have thrown away some years before.
"Have you given up that idea of a yachting cruise of yours, Chalk?" demanded Mr. Tredgold, turning on him suddenly.
"No," was the reply. "I was talking about it to Captain Bowers only the other day. That's how I got to hear of the treasure."
Mr. Tredgold started and gave a significant glance at Mr. Stobell. In return he got a wink which that gentleman kept for moments of mental confusion.
"What did the captain tell you for?" pursued Mr. Tredgold, returning to Mr. Chalk. "He wanted you to make an offer. He hasn't got the money for such an expedition; you have. The yarn about passing his word was so that you shouldn't open your mouth too wide. You were to do the persuading, and then he could make his own terms. Do you see? Why, it's as plain as A B C."
"Plain as the alphabet," said Mr. Stobell, almost chidingly.
Mr. Chalk gasped and looked from one to the other.
"I should like to have a chat with the captain about it," continued Mr. Tredgold, slowly and impressively. "I'm a business man and I could put it on a business footing. It's a big risk, of course; all those things are . . . but if we went shares . . . if we found the money–"
He broke off and, filling his pipe slowly, gazed in deep thought at the wall. His friends waited expectantly.
"Combine business with pleasure," resumed Mr. Tredgold, lighting his pipe; "sea-air . . . change . . . blow away the cobwebs . . . experience for Edward to be left alone. What do you think, Stobell?" he added, turning suddenly.
Mr. Stobell gripped the arms of his chair in his huge hands and drew his bulky figure to a more upright position.
"What do you mean by combining business with pleasure?" he said, eyeing him with dull suspicion.
"Chalk is set on a trip for the love of it," explained Mr. Tredgold.
"If we take on the contract, he ought to pay a bigger share, then," said the other, firmly.
"Perhaps he will," said Tredgold, hastily.
Mr. Stobell pondered again and, slightly raising one hand, indicated that he was in the throes of another idea and did not wish to be disturbed.
"You said it would be experience for Edward to be left alone," he said, accusingly.
"I did," was the reply.
"You ought to pay more, too, then," declared the contractor, "because it's serving of your ends as well."
"We can't split straws," exclaimed Tredgold, impatiently. "If the captain consents we three will find the money and divide our portion, whatever it is, equally."
Mr. Chalk, who had been in the clouds during this discussion, came back to earth again. "If he consents," he said, sadly; "but he won't."
"Well, he can only refuse," said Mr. Tredgold; "and, anyway, we'll have the first refusal. Things like that soon get about. What do you say to a stroll? I can think better while I'm walking."
His friends assenting, they put on their hats and sallied forth. That they should stroll in the direction of Dialstone Lane surprised neither of them. Mr. Tredgold leading, they went round by the church, and that gentleman paused so long to admire the architecture that Mr. Stobell got restless.
"You've seen it before, Tredgold," he said, shortly.
"It's a fine old building," said the other. "Binchester ought to be proud of it. Why, here we are at Captain Bowers's!"
"The house has been next to the church for a couple o' hundred years," retorted his friend.
"Let's go in," said Mr. Tredgold. "Strike while the iron's hot. At any rate," he concluded, as Mr. Chalk voiced feeble objections, "we can see how the land lies."
He knocked at the door and then, stepping aside, left Mr. Chalk to lead the way in. Captain Bowers, who was sitting with Prudence, looked up at their entrance, and putting down his newspaper extended a hearty welcome.
"Chalk didn't like to pass without looking in," said Mr. Tredgold, "and I haven't seen you for some time. You know Stobell?"
The captain nodded, and Mr. Chalk, pale with excitement, accepted his accustomed pipe from
