“Zeal, all zeal,” said Reggie sadly. “Well-meaning man. Only one idea at a time. And sometimes a wrong un.”

“He’s a lawyer by nature,” Lomas apologized. “You always rub him up the wrong way. He don’t like the scientific mind. What?” Bell had come in to give him a visiting card. He read out, “Sir Brian Carwell.” He looked at Reggie. “Now which side is he on?”

“One moment. Who exactly is he? Some sort of remote cousin?”

“Yes. He comes of a younger branch. People say the brains of the Carwell’s went to them. His father was the engineer, old Ralph Carwell. This man’s an engineering contractor. He made his pile over South American railways.”

“You wouldn’t say he was passionately interested in the late Lord Carwell or Cousin Mark.”

There came in a lean man with an air of decision and authority, but older than his resilient vigour suggested, for his hair was much sprinkled with grey, and in his brown face, about the eyes and mouth, the wrinkles were many. He was exact with the formalities of introduction and greeting, but much at his ease, and then, “I had better explain who I am, Mr. Lomas.”

“Oh, we’ve heard of Sir Brian Carwell.”

“Thanks. But I dare say you don’t know my private affairs. I’m some sort of fifteenth cousin of these two unfortunate young fellows. And just now I happen to be the acting head of the family. I’m not the next heir, of course. That’s old Canon Carwell. But I was on the spot when this thing happened. After his arrest Mark asked me to take charge for him, and the Canon wished me to act. That’s my position. Well, I carried on to keep things as they were at the Hall and on the estate. Several of the servants want to quit, of course, but they haven’t gone yet. The butler was a special case. He told me he had given Hugo notice some time before. I could find no record, but it was possible enough, and as he only wanted to retire and settle down in the neighbourhood, I made no difficulty. So he set himself up in lodgings in the village. He was looking about for a house, he told me. I suppose he had done pretty well. He had been in service at the Hall thirty or forty years, poor devil. What a life! He knew Hugo and Mark much better than I do, had known ’em all their young lives. He knew all the family affairs inside and out. One night the people where he was lodging went round to the police to say he’d gone out and not come back. He hasn’t come back yet.”

“And what do you conclude, Sir Brian?”

“I’ll be damned if I know what I conclude. That’s your business, isn’t it?”
