"Why, of course I immediately explained what Constable Gorham had said, and why I had looked in. To which he replied, 'The man's an ass. Get out!' Upon which I closed the door, and the constable and I went away at once." "Constable there with you during it all, then?" "Yes, certainly--in the covered passage, just behind me. He saw and heard everything; though, of course, neither of us actually entered the laboratory itself. There was really no necessity when we knew that my uncle was safe and sound, you see." "Quite so," agreed Cleek. "So you shut the door and went away--and then what?" "Constable Gorham went back to his beat, and I flew as fast as I could to meet Mr. Drummond. It is only a short way to the old bridge at best, and by taking that short cut through the grounds, I was there in less than ten minutes. And by half-past eight I was back here in a greater state of terror than before." "And why? Were you so much alarmed that Mr. Drummond did not keep the appointment?" "No. That did not worry me at all. He is often unable to keep his appointments with me. He is filling the post of private secretary to a large company promoter, and his time is not his own. What terrified me was that, after waiting a few minutes for him, I heard somebody running along the road, and a few moments later Sir Ralph Droger flew by me as if he were being pursued. Under ordinary circumstances I should have thought that he was getting into training for the autumn sports (he is, you may know, very keen on athletics, and holds the County Club's cup for running and jumping), but when I remembered what Constable Gorham had said, and saw that Sir Ralph was coming from the direction of this house, all my wits flew; I got into a sort of panic and almost collapsed with fright." "And all because the man was coming from the direction of this house?"
