"All very well to laugh," replied the inspector, "but at the first stage of affairs it's the only safe principle, and you know that as well as I do, Mr. Trent. However, I've seen enough of the people here, last night and to-day, to put a few of them out of my mind for the present at least. You will form your own conclusions. As for the establishment, there's the butler and lady's maid, cook and three other maids, one a young girl. One chauffeur, who's away with a broken wrist. No boy."

"What about the gardener? You say nothing about that shadowy and sinister figure, the gardener. You are keeping him in the background, Murch. Out with him!"

"The garden is attended to by a man in the village, who comes twice a week. I've talked to him. He was here last on Friday."

"Then I suspect him all the more," said Trent. "And now as to the house itself. What I propose to do, to begin with, is to sniff about a little in this room, where I am told Manderson spent a great deal of his time, and in his bedroom; especially the bedroom. But since we're in this room, let's start here. You seem to be at the same stage of the inquiry. Perhaps you've done the bedroom already?"

The inspector nodded. "I've been through Manderson's and his wife's. Nothing to be got there, I think. Very simple and bare, no signs of any sort—that I could see. Seems to have insisted on the simple life, does Manderson. Never employed a valet. The room's almost like a cell, except for the clothes and shoes. You'll find it all exactly as I found it; and they tell me that's exactly as Manderson left it at we don't know what o'clock yesterday morning. Opens into Mrs. Manderson's bedroom—not much of the cell about that, I can tell you. I should say the lady was as fond of pretty things as most. But she cleared out of it on the morning of the discovery—told the maid she could never sleep in a room opening into her murdered husband's room. Very natural feeling in a woman, Mr. Trent. She's camping out, so to say, in one of the spare bedrooms now."

"Come, my friend," Trent was saying to himself, as he made a few notes in his little book. "Have you got your eye on Mrs. Manderson? Or haven't you? I know that colorless tone of the inspectorial voice. I wish I had seen her. Either you've got something against her and you don't want me to get hold of it; or else you've made up your mind she's innocent, but have no objection to my wasting my time over her. Well, it's all in the game; which begins to look extremely interesting as we go on." To Mr. Murch he said aloud: "Well, I'll draw the bedroom later on. What about this?"

"They call it the library," said the inspector. "Manderson used to do his writing and that in here; passed most of the time he spent indoors here. Since he and his wife ceased to hit it off together, he had taken to spending his evenings alone, and when at this house he always spent 'em in here. He was last seen alive, as far as the servants are concerned, in this room."

Trent rose and glanced again through the papers set out on the table. "Business letters and documents, mostly," said Mr. Murch. "Reports, prospectuses, and that. A few letters on private matters, nothing in them that I can see. The American secretary—Bunner his name is, and a queerer card I never saw turned—he's been through this desk with me this morning. He had got it into his head that Manderson had been receiving threatening letters, and that the murder was the outcome of that. But there's no trace of any such thing; and we looked at every blessed paper. The only unusual things we found were some packets of bank-notes to a very considerable amount, and a couple of little bags of unset diamonds. I asked Mr. Bunner to put them in a safer place. It appears that Manderson had begun buying diamonds lately as a speculation—it was a new game to him, the secretary said, and it seemed to amuse him."

"What about these secretaries?" Trent inquired. "I met one called Marlowe just now outside; a nice-looking chap with singular eyes, unquestionably English. The other, it seems, is an American. What did Manderson want with an English secretary?"

"Mr. Marlowe explained to me how that was. The American was his right-hand business man, one of his office staff, who never left him. Mr. Marlowe had nothing to do with Manderson's business as a financier, knew nothing of it. His job was to look after Manderson's horses and motors and yacht and sporting arrangements and that—make himself generally useful, as you might say. He had the spending of a lot of money, I should think. The other was confined entirely to the office affairs, and I dare say he had his hands full. As for his being English, it was just a fad of Manderson's to have an English secretary. He'd had several before Mr. Marlowe."
