“Probably he does.”

“Then you’ll have to be wary if you’re going to follow him.”

“Trust me,” I replied confidently. “I shall take every precaution.”

We separated, and impatiently I awaited the appearance of the man who was my rival.

Already Mr. Kenway had written to the landlord of the Manor House, and only that morning I had received his consent. Therefore, the matter was concluded, and I held the tenancy of a lonely, weather-worn old place, without possessing a stick of furniture to make it habitable.

But I was anxious to see what manner of man was this Purvis, the smart investigator who had paid half a sovereign for that most precious of all documents. How was it possible that he could have knowledge of the affair, save, perhaps, from the local legend that the Knutton family were entitled to a fortune? The gossip in Rockingham and elsewhere might possibly have aroused his curiosity, but if so he must also have been aware that I held the key to the cipher. Thereby hung a mystery.

Once it occurred to me that Job Seal might be working against me, but on full reflection I saw that such suspicion was unfounded. Seal had foregone his claim in return for half of the gold, and had sailed for the Mediterranean perfectly satisfied.

No. The affair had, I saw, grown into a desperate one; a fortune was awaiting one or other of us—the man who was clever enough to outwit the other.

For an hour I waited at the street corner, my eyes ever upon that flight of steps which led to the dark green sun-blistered door, until I was weary and exhausted. Purvis was undoubtedly having tea and gossiping with the widow.

I saw my friend the servant girl come to the dining-room window, pull the yellow lace curtains aside, and, putting her head out, look up and down the street. She caught sight of me, and with the knowledge that I was on guard, quickly withdrew.
