The coachman looked round amongst the listeners as if he were a little perplexed. “Why, sir,” he answered, turning back to Barthorpe, “there was nothing happened! At least, I mean to say, there was nothing happened that didn’t always happen on such occasions—Mr. Herapath got out of the brougham, shut the door, said ‘Good night,’ and went up the steps, taking his latch-key out of his pocket as he crossed the pavement, sir. That was all, sir.”

“Did you actually see him enter the house?”

“No, sir,” replied Mountain, with a decisive shake of the head. “I couldn’t say that I did that. I saw him just putting the key in the latch as I drove off.”

“And that’s all you know?”

“That’s all I know, sir—all.”

Barthorpe, after a moment’s hesitation, turned to the police-inspector.

“Is there anything that occurs to you?” he asked.

“One or two things occur to me,” answered the inspector. “But I’m not going to ask any questions now. I suppose all you want at present is to get a rough notion of how things were last night?”

“Just so,” assented Barthorpe. “A rough notion—that’s it. Well, Kitteridge, it’s your turn. Who found out that Mr. Herapath wasn’t in the house this morning?”

“Charlesworth, sir—Mr. Herapath’s valet,” replied the butler. “He always called Mr. Herapath at a quarter past seven every morning. When he went into the bedroom this morning Mr. Herapath wasn’t there, and the bed hadn’t been slept in. Then Charlesworth came and told me, sir, and of course I went to the study at once, and then I saw that, wherever Mr. Herapath might be then, he certainly had been home.”
