His question now was: Where would Roper make his cache? Not near the road where the disturbed earth would be visible to a chance passerby. Not near the house in case some of the crowds attracted by the fire should make an unexpected find. But not too far away from either lest he himself might have difficulty in locating the place.

French began to walk round the house in circles of ever increasing radius, scrutinising the ground for traces of yellow clay. And so he searched until the evening began to draw in and dusk approached.

And then, as he was coming to the conclusion that it was getting too dark to carry on, he found what he wanted. Out on the open moor at the back of the house and at the bottom of a tiny hollow were unmistakable traces of recent digging. The ground over a few square feet was marked with scraps of disintegrating yellow clay and the sods with which the hole was covered still showed cut edges.

French was overwhelmed with delight. That he had found something of value, most probably a cache containing the stolen money, he had no doubt. Scarcely could he restrain his desire to open the hole again then and there. But it was getting dark and he had no lamp. He thought two witnesses would be desirable, so he curbed his impatience, noted carefully the position of the marks, and regretting the necessity for leaving it unguarded, set off on his return journey.

He called to see Sergeant Kent and arranged that he and a constable should meet him at the outhouse at eight o’clock on the following morning. At the hotel he dined, and saying that he had to take the night train to Carlisle, asked for a packet of sandwiches. Then he left the town and walked out once more to Starvel.

His mind was not at rest until he had again visited the site of the hole and made sure it remained undisturbed. Then, determined to take no chances, he re-entered the outhouse, and seating himself at a window from which he could see the hollow in the light of the moon, lit his pipe and composed himself to watch.

CHAPTER FOURTEEN: The Secret of the Moor

That night in the lonely shed beside the gaunt, blackened walls of the old house, proved one of the longest French had ever spent. But there was no escape from the vigil. If Averill’s hoard lay beneath the sods a few yards away, the place must be watched. Roper might come for the swag at any time and French could not run the risk of its being snatched at the last moment from his own eager clutches.

He pulled a couple of old boxes to the window, and sitting down, made himself as comfortable as he could. But time dragged leadenly. He watched while the moon crept slowly across the sky, he speculated over the tragic business on which he was engaged and indulged in waking dreams of the time when he should be Chief Inspector French of the C.I.D., but nothing that he could do seemed to shorten the endless hours. He was cold, too, in spite of his heavy coat. He longed to go out and warm himself by a brisk walk, but he dared not risk betraying his presence. In the small hours he ate his sandwiches, and then he had to fight an overwhelming desire for sleep, intensified by the fact that he had been up a good part of the previous night. But his vigilance was unrewarded. There was no sign of a marauder, and as the first faint glow of dawn began to show in the east, he saw that he had had all his trouble for nothing. Altogether he was not sorry when just before eight o’clock Sergeant Kent and the constable put in an appearance, and as he stepped out to meet them he heaved a sigh of heartfelt relief.

“You’re here before us,” Kent greeted him in surprise.
