Sergeant Cuff was just as quick on his side. He put Samuel back, and stood before Miss Rachel, with the open carriage-door in his hand, at the instant when she settled herself in her place.

"What do you want?" says Miss Rachel, from behind her veil.

"I want to say one word to you, miss," answered the Sergeant, "before you go. I can't presume to stop your paying a visit to your aunt. I can only venture to say that your leaving us, as things are now, puts an obstacle in the way of my recovering your Diamond. Please to understand that; and now decide for yourself whether you go or stay."

Miss Rachel never even answered him. "Drive on, James!" she called out to the coachman.

Without another word, the Sergeant shut the carriage-door. Just as he closed it, Mr. Franklin came running down the steps. "Good-bye, Rachel," he said, holding out his hand.

"Drive on!" cried Miss Rachel, louder than ever, and taking no more notice of Mr. Franklin than she had taken of Sergeant Cuff.

Mr. Franklin stepped back thunderstruck, as well he might be. The coachman, not knowing what to do, looked towards my lady, still standing immovable on the top step. My lady, with anger and sorrow and shame all struggling together in her face, made him a sign to start the horses, and then turned back hastily into the house. Mr. Franklin, recovering the use of his speech, called after her, as the carriage drove off, "Aunt! you were quite right. Accept my thanks for all your kindness - and let me go."

My lady turned as though to speak to him. Then, as if distrusting herself, waved her hand kindly. "Let me see you, before you leave us, Franklin," she said, in a broken voice - and went on to her own room.

"Do me a last favour, Betteredge," says Mr. Franklin, turning to me, with the tears in his eyes. "Get me away to the train as soon as you can!"

He too went his way into the house. For the moment, Miss Rachel had completely unmanned him. Judge from that, how fond he must have been of her!

Sergeant Cuff and I were left face to face, at the bottom of the steps. The Sergeant stood with his face set towards a gap in the trees, commanding a view of one of the windings of the drive which led from the house. He had his hands in his pockets, and he was softly whistling "The Last Rose of Summer" to himself.

"There's a time for everything," I said savagely enough. "This isn't a time for whistling."

At that moment, the carriage appeared in the distance, through the gap, on its way to the lodge-gate. There was another man, besides Samuel, plainly visible in the rumble behind.

"All right!" said the Sergeant to himself. He turned round to me. "It's no time for whistling, Mr. Betteredge, as you say. It's time to take this business in hand, now, without sparing anybody. We'll begin with Rosanna Spearman. Where is Joyce?"

We both called for Joyce, and received no answer. I sent one of the stable-boys to look for him.

"You heard what I said to Miss Verinder?" remarked the Sergeant, while we were waiting. "And you saw how she received it? I tell her plainly that her leaving us will be an obstacle in the way of my recovering her Diamond - and she leaves, in the face of that statement! Your young lady has got a travelling companion in her mother's carriage, Mr. Betteredge - and the name of it is, the Moonstone."

I said nothing. I only held on like death to my belief in Miss Rachel.

The stable-boy came back, followed - very unwillingly, as it appeared to me - by Joyce.

"Where is Rosanna Spearman?" asked Sergeant Cuff.

"I can't account for it, sir," Joyce began; "and I am very sorry. But somehow or other - - "

"Before I went to Frizinghall," said the Sergeant, cutting him short, "I told you to keep your eyes on Rosanna Spearman, without allowing her to discover that she was being watched. Do you mean to tell me that you have let her give you the slip?"

"I am afraid, sir," says Joyce, beginning to tremble, "that I was perhaps a little TOO careful not to let her discover me. There are such a many passages in the lower parts of this house - - "

"How long is it since you missed her?"

"Nigh on an hour since, sir."

"You can go back to your regular business at Frizinghall," said the Sergeant, speaking just as composedly as ever, in his usual quiet and dreary way. "I don't think your talents are at all in our line, Mr. Joyce. Your present form of employment is a trifle beyond you. Good morning."

The man slunk off. I find it very difficult to describe how I was affected by the discovery that Rosanna Spearman was missing. I seemed to be in fifty different minds about it, all at the same time. In that state, I stood staring at Sergeant Cuff - and my powers of language quite failed me.

"No, Mr. Betteredge," said the Sergeant, as if he had discovered the uppermost thought in me, and was picking it out to be answered, before all the rest. "Your young friend, Rosanna, won't slip through my fingers so easy as you think. As long as I know where Miss Verinder is, I have the means at my disposal of tracing Miss Verinder's accomplice. I prevented them from communicating last night. Very good. They will get together at Frizinghall, instead of getting together here. The present inquiry must be simply shifted (rather sooner than I had anticipated) from this house, to the house at which Miss Verinder is visiting. In the meantime, I'm afraid I must trouble you to call the servants together again."

I went round with him to the servants' hall. It is very disgraceful, but it is not the less true, that I had another attack of the detective-fever, when he said those last words. I forgot that I hated Sergeant Cuff. I seized him confidentially by the arm. I said, "For goodness' sake, tell us what you are going to do with the servants now?"

The great Cuff stood stock still, and addressed himself in a kind of melancholy rapture to the empty air.

"If this man," said the Sergeant (apparently meaning me), "only understood the growing of roses he would be the most completely perfect character on the face of creation!" After that strong expression of feeling, he sighed, and put his arm through mine. "This is how it stands," he said, dropping down again to business. "Rosanna has done one of two things. She has either gone direct to Frizinghall (before I can get there), or she has gone first to visit her hiding-place at the Shivering Sand. The first thing to find out is, which of the servants saw the last of her before she left the house."

On instituting this inquiry, it turned out that the last person who had set eyes on Rosanna was Nancy, the kitchenmaid.

Nancy had seen her slip out with a letter in her hand, and stop the butcher's man who had just been delivering some meat at the back door. Nancy had heard her ask the man to post the letter when he got back to Frizinghall. The man had looked at the address, and had said it was a roundabout way of delivering a letter directed to Cobb's Hole, to post it at Frizinghall - and that, moreover, on a Saturday, which would prevent the letter from getting to its destination until Monday morning, Rosanna had answered that the delivery of the letter being delayed till Monday was of no importance. The only thing she wished to be sure of was that the man would do what she told him. The man had promised to do it, and had driven away. Nancy had been called back to her work in the kitchen. And no other person had seen anything afterwards of Rosanna Spearman.

"Well?" I asked, when we were alone again.

"Well," says the Sergeant. "I must go to Frizinghall."

"About the letter, sir?"

"Yes. The memorandum of the hiding-place is in that letter. I must see the address at the post-office. If it is the address I suspect, I shall pay our friend, Mrs. Yolland, another visit on Monday next."

I went with the Sergeant to order the pony-chaise. In the stable-yard we got a new light thrown on the missing girl.
