But Mrs. Bunting made no answer.

Bunting went off, back into the sitting-room. The water was boiling now, so he made the tea; and then, as he brought the little tray in, his heart softened. Ellen did look really ill—ill and wizened. He wondered if she had a pain about which she wasn’t saying anything. She had never been one to grouse about herself.

“The lodger and me came in together last night,” he observed genially. “He’s certainly a funny kind of gentleman. It wasn’t the sort of night one would have chosen to go out for a walk, now was it? And yet he must ’a been out a long time if what he said was true.”

“I don’t wonder a quiet gentleman like Mr. Sleuth hates the crowded streets,” she said slowly. “They gets worse every day—that they do! But go along now; I want to get up.”

He went back into their sitting-room, and, having laid the fire and put a match to it, he sat down comfortably with his newspaper.

Deep down in his heart Bunting looked back to this last night with a feeling of shame and self-rebuke. Whatever had made such horrible thoughts and suspicions as had possessed him suddenly come into his head? And just because of a trifling thing like that blood. No doubt Mr. Sleuth’s nose had bled—that was what had happened; though, come to think of it, he had mentioned brushing up against a dead animal.

Perhaps Ellen was right after all. It didn’t do for one to be always thinking of dreadful subjects, of murders and such-like. It made one go dotty—that’s what it did.

And just as he was telling himself that, there came to the door a loud knock, the peculiar rat-tat-tat of a telegraph boy. But before he had time to get across the room, let alone to the front door, Ellen had rushed through the room, clad only in a petticoat and shawl.

“I’ll go,” she cried breathlessly. “I’ll go, Bunting; don’t you trouble.”

He stared at her, surprised, and followed her into the hall.
