"Whatever you may say, you've got some suspicion about my father," she remarked after a pause. "Well—all I can say is, my father has no need to rob anybody—far from it, if you want the truth. But what do you want?" she continued, a little impatiently. "My father isn't in, and I don't know where he is—often he is out all night."

"If we could just look round his shed, now?" said the sergeant. "Just to see if aught's missing, like, you know. You see, miss——"

"You can look round the shed—and round anywhere else," said Avice. "Though what good that will do—well, you know where the shed is."

She turned away and began taking off her hat and coat, and the four men went out into the garden and turned to the lean-to shed at the end of the cottage. A tiled verandah ran along the front of cottage and shed, and the door of the shed was at its further end. But as the sergeant was about to open it, the policeman of the observant nature made his third discovery. He had been flashing the light of his bull's-eye lamp over his surroundings, and he now turned it on a coil of rope which hung from a nail in the boarded wall of the shed, between the door and the window.

"There you are, gentlemen!" he said, lifting the lamp in one hand and pointing triumphantly to a definite point of the coiled cord with the index finger of the other. "There! Cut clean, too—just like the bit up yonder!"

Brereton pressed forward and looked narrowly at what the man was indicating. There was no doubt that a length of cord had been freshly cut off the coil, and cut, too, with an unusually sharp, keen-bladed knife; the edges of the severance were clean and distinct, the separated strands were fresh and unsoiled. It was obvious that a piece of that cord had been cut from the rest within a very short time, and the sergeant shook his head gravely as he took the coil down from its nail.

"I don't think there's any need to look round much further, Mr. Bent," he said. "Of course, I shall take this away with me, and compare it with the shorter piece. But we'll just peep into this shed, so as to make his daughter believe that was what we wanted: I don't want to frighten her more than we have done. Naught there, you see," he went on, opening the shed door and revealing a whitewashed interior furnished with fittings and articles of its owner's trade. "Well, we'll away—with what we've got."

He went back to the door of the cottage and putting his head inside called gently to its occupant.

"Well?" demanded Avice.

"All right, miss—we're going," said the sergeant. "But if your father comes in, just ask him to step down to the police-station, d'you see?—I should like to have a word or two with him."
