"How killed, Sir Henry? Stabbed or shot?"

"Neither. He appeared to have been strangled, poor fellow, and to have died in most awful agony."

"Strangled! But, my dear sir, that would hardly have been possible in so short a time. You say your men heard him call out for help. Granted that it took them a full minute—and it probably did not take them half one—to open the doors and come to his assistance, he would not be stone dead in so short a time; and he was stone dead when they got in, I believe you said?"

"Yes. God knows what killed him, the coroner will find that out, no doubt, but there was no blood shed and no mark upon him that I could see."

"Hum-m-m! Was there any mark on the door of the steel stall?"

"Yes. A long scratch, somewhat semi-circular, and sweeping downward at the lower extremity. It began close to the lock and ended about a foot and a half lower."

"Undoubtedly, you see, Cleek," put in Narkom, "some one tried to force an entrance to the steel room and get at the mare, but the prompt arrival of the men on guard outside the stable prevented his doing so."

Cleek made no response. Just at that moment the limousine was gliding past a building whose courtyard was one blaze of parrot tulips, and, his eye caught by the flaming colours, he was staring at them and reflectively rubbing his thumb and forefinger up and down his chin. After a moment, however:

"Tell me something, Sir Henry," he said abruptly. "Is anybody interested in your not putting Black Riot into the field on Derby Day? Anybody with whom you have a personal acquaintance, I mean, for of course I know there are other owners who would be glad enough to see him scratched. But is there anybody who would have a particular interest in your failure?"
