Upon the table we compared the tracing given us by Fairbairn with the copy of old Godfrey’s plan made by Fred, and Mr Mason recognising the points where we were of course in ignorance, we came, after a long and careful examination and comparison, to the conclusion that the wealth of the abbey as enumerated in The Closed Book was concealed at a spot nearly a mile from the abbey, in the centre or the Great Postland Fen, in a field which was on his own property—for he was squire of the place, as well as rector—about midway between Thornbury Hall and the Decoy Farm. The position of St. James’ Bridge and the ancient stone cross at Brotherhouse were both shown, as well as the old Asen Dike and the Wash-bank at Cloot. The plan showed that the old abbot was crafty enough to carry the treasure sufficiently far into what must at the time have been a dangerous quagmire, wherein none dare venture who knew not the way, but which has of course since been drained and reclaimed by the building of banks and cutting of dikes in all directions. Mr Mason told us that the whole of the district shown on the plan was until the end of the sixteenth century a dismal, unhealthy swamp, the sparse inhabitants of which were fever-stricken, and the spot where the treasure was apparently concealed was in the deepest part of the basin, and in all probability a treacherous bog purposely chosen in order to defeat any efforts of Southwell’s soldiers.

The allegation in The Closed Book that gold and silver objects had been sunk in the fish pond was no doubt in order to mislead, for, after all, it was not likely that the abbot should make so little attempt to effectively conceal what he wished to rescue from sacriligious hands.

“Depend upon it, gentlemen, we’re on the right track at last,” declared the rector decisively. He was an archaeologist himself, and was eager to see our splendid find of gems, just as he was eager to recover the long-lost treasure of the Abbot John.

The measurements on the plan which had so cunningly been concealed were given in paces from St. James’ Bridge, about a mile to the south-east of the abbey, and Mr Mason suggested that having regard to the fact that Selby and his companions had the original plan in their possession, we should lose no time in going to the spot.

I glanced at my watch, and found it to be a quarter-past one in the morning.

Fred drew the blind aside and discovered that it was not a particularly dark night, although heavy rain-clouds had drifted across the moon. The suggestion to fix the spot was a good one, although it was arranged that as the land was Church property, and there was no reason for secret search, the excavations should be carried out on the morrow.

Together, the five of us, having borrowed two lanterns from the hotel keeper, left the house, and under the guidance of Mr Mason passed down the road beside the rectory, skirted the north wall of the abbey, and then out upon the broad, flat high road, past the dilapidated windmill, and on to St. James’ Bridge, where we took another road eastward, flat, hedgeless, uninteresting like the first, and running straight as an arrow towards our destination.

Presently the rector halted and pointed out a distant clump of trees looming in the darkness as Thornbury Hall, while to our left lay the Decoy Farm. Beneath the uncertain rays of the lamp he carefully examined the plan again, and then led us through a gate into a large field sown with fen-potatoes, which we crossed carefully in the darkness for fear of falling into the dikes which in that country separate one field from another. At last we found the boundary, and discovered a single plank which gave access to the next field, with a crop of potatoes like the first. Then, having counted his paces carefully from the roadway, his face always turned to Thornbury Hall, he suddenly halted, saying:

“The actual spot is here, or within a few feet. According to the plan, it is one hundred and eighty-six paces due south towards Thornbury from the road anciently known as Guthlac’s Drove—the road we have just left.”

We lowered the lanterns, and groping about, examined the ground. The crop had certainly not been disturbed. We stamped just as we had done at Threave, but there was no hollow sound in the heavy fen clay.
