“Before leaving the house, it occurred to me that I ought to look into the laboratory and see if there was anything my uncle would be likely to need for the night, as I intended to go straightway to bed on my return. I did so. He was sitting at his desk, immediately under the one window of which I have spoken, and with his back to me, when I looked in. He answered my inquiry with a curt ‘No—nothing. Get out and don’t worry me!’ I immediately shut the door and left him, returning here by way of the covered passage and going upstairs to make some necessary changes in my dress for the walk to the old bridge. When I came down, ready for my journey, I looked at the clock on the mantel over there. It was exactly seventeen minutes to eight o’clock. I had been a little longer in dressing than I had anticipated being; so, in order to save time in getting to the trysting place, I concluded to make a short cut by going out of the rear door and crossing diagonally through our grounds instead of going by the public highway as usual. I had scarcely more than crossed the threshold when I ran plump into Constable Gorham. As he is rather a favourite with good Mrs. Armroyd here, I fancied that he had been paying her a visit, and was just coming away from the kitchen. Instead, he rather startled me by stating that he had seen something which he thought best to come round and investigate. In short, that, as he was patrolling the highway, he had seen a man vault over the wall of our grounds and, bending down, dart out of sight like a hare. He was almost positive that that man was Sir Ralph Droger. Of course that frightened me almost out of my wits.”

“Why?”

“There was bad blood between my uncle and Sir Ralph Droger—bitter, bad blood. As you perhaps know, my uncle held this ground on a life lease from the Droger estate. That is to say, so long as he lived or refused to vacate that lease, no Droger could oust him nor yet lift one spadeful of earth from the property.”

“Does Sir Ralph desire to do either?”

“He desires to do both. Borings secretly made have manifested the fact that both Barnsley thick-coal and iron ore underlie the place. Sir Ralph wishes to tear down the Round House and this building and to begin mining operations. My uncle, who has been offered the full value of every stick and stone, has always obstinately refused to budge one inch or to lessen the lease by one half hour. ‘It is for the term of my life,’ he has always said, ‘and for the term of my life I’ll hold it!’”

“Oho!” said Cleek; and then puckered up his lips as if about to whistle.

“Under such circumstances,” went on Miss Renfrew, “it was only natural that I should be horribly frightened, and only too willing to act upon the constable’s suggestion that we at once look into the Round House and see if everything was right with my uncle.”

“Why should the constable suggest that?”

“Everybody in the neighbourhood knows of the bitter ill feeling existing between the two men; so, of course, it was only natural.”

“Hum-m-m! Yes! Just so. Did you act on Constable Gorham’s suggestion, then?”
