"Let's see the tinker first," said Neale. "He's a sharp man—he may have something else to tell by now."

He led his companion out of the town by way of Scarnham Bridge, pointing out Joseph Chestermarke's gloomy house to her as they passed it.

"I'd give a lot," he remarked, as they turned on to the open moor which led towards Ellersdeane Hollow, "to know if either of the Chestermarkes really did know anything about that chap Hollis coming to the town on Saturday. I shouldn't be a bit surprised if they did. Those detective fellows like Starmidge are very clever in their way, but they always seem to me to stop thinking a bit too soon. Now both Starmidge and Polke seem to take it for certain that this Hollis went to meet Horbury when he left the Station Hotel. There's no proof that he went to meet Horbury—none!"

"Whom might he have gone to meet, then?" demanded Betty.

"You listen to me a bit," said Neale. "I've been thinking it over. Hollis comes to the Station Hotel and uses their telephone. Mrs. Pratt overhears him call up Chestermarke's Bank—that's certain. Then she goes away, about her business. An interval elapses. Then she hears some appointment made, with somebody, along the river bank, for that evening. But—that interval during which Mrs. Pratt didn't overhear? How do we know that the person with whom Hollis began his conversation was the same person with whom he finished it? Come, now!"

"Wallie, that's awfully clever of you!" exclaimed Betty. "How did you come to think of such an ingenious notion?"

"Worked it out," answered Neale. "This way! Hollis comes down to Scarnham to see Chestermarke's Bank—which means one of the partners. He rings up the bank. He speaks to somebody there. How do we know that somebody was Horbury? We don't! It may have been Mrs. Carswell. Now supposing the real person Hollis wanted to see was either Gabriel or Joseph Chestermarke? Very well—this person who answered from the bank would put Hollis on to either of them at once. Gabriel has a telephone at the Warren: Joseph has a telephone at his home yonder behind us. It may have been with either Gabriel or Joseph that Hollis finished his conversation. And—if it was finished with one of them, it was, in my opinion, whatever that's worth, with Master Joseph!"

"What makes you think that?" asked Betty, startled by the suggestion.

Neale laid a hand on the girl's arm and turned her round to face the town. He lifted his stick and pointed at Joseph Chestermarke's high roof, towering above the houses around it; then he swept the stick towards the river and its course, plainly to be followed, in the direction of the station.

"You see Joseph's house there," he said. "You see the river—the path along its bank—going right down to the meadow opposite the Station Hotel? Very well—now, supposing it was Joseph with whom Hollis wound up that telephone talk, suppose it was Joseph whom Hollis was to see. What would happen? Joseph knew that Hollis was at the Station Hotel. The straightest and easiest way from the Station Hotel to Joseph's house is—straight along the river bank. Now then, call on your memory! What did Mrs. Pratt tell us? 'When I was going back to the bar,' says Mrs. Pratt, 'I heard more. "Along the river-side," says the gentleman. "Straight on from where I am—all right." Then, after a minute, "At seven-thirty, then?" he says. "All right—I'll meet you." And after that,' concludes Mrs. Pratt, 'he rings off.' Now, why shouldn't it be Joseph Chestermarke that he was going to meet?—remember, again, the river-side path leads straight to Joseph's house. Come!—Mrs. Pratt's story doesn't point conclusively to Horbury at all. It's as I say—the telephone conversation may have begun with Horbury, but it may have ended with—somebody else. And what I say is—who was the precise person whom Hollis went to meet?"
