When dusk fell we again called upon the rector, explained how we had discovered the presence of our rivals and their intentions, and arranged to return to him at ten o’clock. The feature of the case that aroused the rector’s indignation—and most justly, too—was the intention of the others to search without permission. To me, their mode of facing matters boldly showed that they were in possession of positive information, and relied upon securing the treasure and getting away before anyone knew of their intentions.

When Walter once took up an inquiry, or set out upon a journey, he never rested until his object was accomplished. He was one of those men who seem continually active, and unable to rest in idleness for ten consecutive minutes, and, happy possessor of such a fine physique, was never tired. We watched the pair away from the “White Hart” again, for they were both smoking and wandering about, apparently enjoying the rural quiet, but in reality awaiting darkness. Then, when they had gone away—in the direction of the old South Eau, we learned—we both lounged into their inn, and called for ale, and chatted with the rosy-cheeked servant who brought it. A judicious sixpence released her tongue, and by careful questions we soon learned all we wished about the two guests. They were staying till morning, but did not expect any visitors. One, the tall gentleman, was a doctor, and might be recalled; therefore their coachman from Peterborough, who would remain there also, might be called up during the night, and they would be compelled to leave. His lordship had recourse to a clever fiction then. He was a doctor who might be called in the middle of the night! I suppose it never occurred to the rustic mind that, if a doctor, his practice was not in Crowland, and therefore he was scarcely likely to receive an urgent call.

The other man, she told us, was a foreigner. They had brought a bag full of papers and plans, but kept it locked. Both took a great interest in old ruins, and for that reason they had taken some measurements.

One fact she forgot she remarked before going out. The tall gentleman had said that a young lady might arrive during the evening and inquire for him. If she did, she was to be asked to wait.

A young lady! Was it possible that Judith was about to follow her father there?

As ten o’clock chimed from the abbey bells we took our candles, and, wishing the worthy landlord good-night, went to our rooms and there waited until all was still. Crowlanders retire early to bed, and presumably the policeman, like all others, has to meet another guardian of the peace, perhaps, at the end of that long, straight old road called Kennulph’s Drove, that runs towards Peterborough, for we saw nothing of him when we carefully crept down, drew the bolts, unlocked the door, and, closing it noiselessly after us, made our way to the rectory.

Mr Mason, ready attired in hat and overcoat, opened his door noiselessly ere we had approached it, and we slipped into his study to tell him all that we had witnessed. Then, feeling that we ought to go forth at once and take up our position to watch, we all went out, skirting the churchyard and passing down behind the high hawthorn hedge which formed the boundary of the field wherein were traces of the fish ponds.

The night was dark and starless, with that oppressive stillness that foretokened a storm. Behind us lay the black ruins of the abbey, rearing high and gloomy; and as we passed along, led by the rector, who knew every nook and corner, a silence fell upon us.

The rector’s object was to approach the spot marked with the paper and stone as near as possible, yet having good cover to conceal us. In this he was eminently successful; for, having traversed the field on two sides, he suddenly suggested that we should crouch down in a low hedge only thirty yards from the scene of operations.

We conversed together in low, expectant whispers for almost an hour, until, indeed, the rector began to fear that our vigilance was in vain, when of a sudden we heard on the hard road far distant the sound of wheels approaching, on the road skirting the village on the Welland side, Mr Mason declared.
