“Hould on,” said Corson, “I was near forgetting. I've got a master-key that fits most of these locks. It's handy for closing up a warehouse when some clerk with his wits a-wandering forgits his job. So like enough it's good at unlocking.”
It needed a little coaxing, but the bolt at last slid back and the heavy doors swung open. The room was furnished with a large table, a big desk, and a dozen chairs, which sprang out of the darkness as I struck a match and lit the gas. It was evidently the council-room of the enemy.
“This is illigant,” said the policeman, looking around with approval; “but your man isn't here, I'd say.”
“Well, it looks as though there might be something here of interest,” I replied, seizing eagerly upon the papers that lay scattered about upon the desk. “Look in the other rooms while I run through these.”
A rude diagram on the topmost paper caught my eye. It represented a road branching thrice. On the third branch was a cross, and then at intervals four crosses, as if to mark some features of the landscape. Underneath was written:
“From B—follow 1 1-2 m. Take third road—3 or 5.”
The paper bore date of that day, and I guessed that it was meant to show the way to the supposed hiding-place of the boy.
Then, as I looked again, the words and lines touched a cord of memory. Something I had seen or known before was vaguely suggested. I groped in the obscurity for a moment, vainly reaching for the phantom that danced just beyond the grasp of my mental fingers.
There was no time to lose in speculating, and I turned to the work that pressed before us. But as I thrust the papers into my pocket to resume the search for Barkhouse, the elusive memory flashed on me. The diagram of the enemy recalled the single slip of paper I had found in the pocket of Henry Wilton's coat on the fatal night of my arrival. I had kept it always with me, for it was the sole memorandum left by him of the business that had brought him to his death. I brought it out, very badly creased and rumpled from much carrying, but still quite as legible as on the night I had first seen it.
Placed side by side with the map I had before me, the resemblance was less close than I had thought. Yet all the main features were the same. There was the road branching thrice; a cross in both marked the junction of the third road as though it gave sign of a building or some natural landmark; and the other features were indicated in the same order. No—there was a difference in this point; there were five crosses on the third road in the enemy's diagram, while there were but four in mine.
