Drawing near the house he saw that the great oaken door stood open, letting a shaft of hot, clean, morning sunlight paint a golden track across the polished floor of the wide hall. He entered, flung his hat on to a chair, and turned in the direction of the stairs. He had set foot upon the third step when from behind and below him came a noise—a rasping roar of a noise. To his overtired brain and overheated imagination it seemed a noise evil and inhuman. He swung round. The hall was as he had left it, empty of all save furniture. He descended the three steps; stood looking about him; then walked towards the front door. Before he could reach it, the noise came again, louder this time. The same roaring, rasping sound. But this time it had for a tail a snuffling choke which came, obviously, from the throat of a man. Anthony laughed at himself. Noiselessly, he retraced his steps, passed the foot of the stairs, and halted outside the door opposite that of the study. It stood ajar, giving him a glimpse of the little room which he remembered as being the lair of the butler. Anthony waited. In a moment came the roar again, now recognisable as half-cough, half-sneeze. Anthony pushed the door wide. Facing it, huddled in a chair, was the butler. His gray head was on a level with his knees. In one claw of a hand he clutched a bandanna handkerchief with which he dabbed every now and then at his streaming eyes. Anthony stood unmoving in the doorway. Presently, another spasm shook the old man. “Bad cold, that,” Anthony said loudly. There was no answer. The coughing gasps went on; gradually grew less frequent. The thin shoulders ceased to shake. “Bad cold, that,” said Anthony again. This time he got an effect. Poole leapt to his feet, fumbling hurriedly to hide in a tail pocket the capacious handkerchief. “Your pardon, sir!” he gasped. “Did you want me, sir?” “I only remarked that yours was a bad cold.” “Thank you, sir. Thank you. Not that it’s a cold, sir, exactly. It’s this hay-fever. And very troublesome it is, sir, for an old fellow like me!” “Must be.” Anthony was sympathetic. “D’you have these attacks many times a day?” “I used to, sir. But this summer it does seem to be improving, sir. Only takes me every now and then, as you might say.” The old man’s voice showed gratitude for this concern about his ailment. But Anthony’s interest in hay-fever was not yet abated. “This the first bad fit you’ve had for some time?” he asked. “Yes, sir. Quite a while since I was so bad, sir. It didn’t trouble me at all yesterday, sir.” Anthony drew nearer. “D’you happen to remember,” he said slowly, “whether you—er—sneezed like that at all on the evening your master was killed?”
