Nothing happened in the night; and (I am happy to add) no attempt at communication between Miss Rachel and Rosanna rewarded the vigilance of Sergeant Cuff.

I had expected the Sergeant to set off for Frizinghall the first thing in the morning. He waited about, however, as if he had something else to do first. I left him to his own devices; and going into the grounds shortly after, met Mr. Franklin on his favourite walk by the shrubbery side.

Before we had exchanged two words, the Sergeant unexpectedly joined us. He made up to Mr. Franklin, who received him, I must own, haughtily enough. "Have you anything to say to me?" was all the return he got for politely wishing Mr. Franklin good morning.

"I have something to say to you, sir," answered the Sergeant, "on the subject of the inquiry I am conducting here. You detected the turn that inquiry was really taking, yesterday. Naturally enough, in your position, you are shocked and distressed. Naturally enough, also, you visit your own angry sense of your own family scandal upon Me."

"What do you want?" Mr. Franklin broke in, sharply enough.

"I want to remind you, sir, that I have at any rate, thus far, not been PROVED to be wrong. Bearing that in mind, be pleased to remember, at the same time, that I am an officer of the law acting here under the sanction of the mistress of the house. Under these circumstances, is it, or is it not, your duty as a good citizen, to assist me with any special information which you may happen to possess?"

"I possess no special information," says Mr. Franklin.

Sergeant Cuff put that answer by him, as if no answer had been made.

"You may save my time, sir, from being wasted on an inquiry at a distance," he went on, "if you choose to understand me and speak out."

"I don't understand you," answered Mr. Franklin; "and I have nothing to say."

"One of the female servants (I won't mention names) spoke to you privately, sir, last night."

Once more Mr. Franklin cut him short; once more Mr. Franklin answered, "I have nothing to say."

Standing by in silence, I thought of the movement in the swing-door on the previous evening, and of the coat-tails which I had seen disappearing down the passage. Sergeant Cuff had, no doubt, just heard enough, before I interrupted him, to make him suspect that Rosanna had relieved her mind by confessing something to Mr. Franklin Blake.

This notion had barely struck me - when who should appear at the end of the shrubbery walk but Rosanna Spearman in her own proper person! She was followed by Penelope, who was evidently trying to make her retrace her steps to the house. Seeing that Mr. Franklin was not alone, Rosanna came to a standstill, evidently in great perplexity what to do next. Penelope waited behind her. Mr. Franklin saw the girls as soon as I saw them. The Sergeant, with his devilish cunning, took on not to have noticed them at all. All this happened in an instant. Before either Mr. Franklin or I could say a word, Sergeant Cuff struck in smoothly, with an appearance of continuing the previous conversation.

"You needn't be afraid of harming the girl, sir," he said to Mr. Franklin, speaking in a loud voice, so that Rosanna might hear him. "On the contrary, I recommend you to honour me with your confidence, if you feel any interest in Rosanna Spearman."

Mr. Franklin instantly took on not to have noticed the girls either. He answered, speaking loudly on his side:

"I take no interest whatever in Rosanna Spearman."

I looked towards the end of the walk. All I saw at the distance was that Rosanna suddenly turned round, the moment Mr. Franklin had spoken. Instead of resisting Penelope, as she had done the moment before, she now let my daughter take her by the arm and lead her back to the house.

The breakfast-bell rang as the two girls disappeared - and even Sergeant Cuff was now obliged to give it up as a bad job! He said to me quietly, "I shall go to Frizinghall, Mr. Betteredge; and I shall be back before two." He went his way without a word more - and for some few hours we were well rid of him.

"You must make it right with Rosanna," Mr. Franklin said to me, when we were alone. "I seem to be fated to say or do something awkward, before that unlucky girl. You must have seen yourself that Sergeant Cuff laid a trap for both of us. If he could confuse ME, or irritate HER into breaking out, either she or I might have said something which would answer his purpose. On the spur of the moment, I saw no better way out of it than the way I took. It stopped the girl from saying anything, and it showed the Sergeant that I saw through him. He was evidently listening, Betteredge, when I was speaking to you last night."

He had done worse than listen, as I privately thought to myself. He had remembered my telling him that the girl was in love with Mr. Franklin; and he had calculated on THAT, when he appealed to Mr. Franklin's interest in Rosanna - in Rosanna's hearing.

"As to listening, sir," I remarked (keeping the other point to myself), "we shall all be rowing in the same boat if this sort of thing goes on much longer. Prying, and peeping, and listening are the natural occupations of people situated as we are. In another day or two, Mr. Franklin, we shall all be struck dumb together - for this reason, that we shall all be listening to surprise each other's secrets, and all know it. Excuse my breaking out, sir. The horrid mystery hanging over us in this house gets into my head like liquor, and makes me wild. I won't forget what you have told me. I'll take the first opportunity of making it right with Rosanna Spearman."

"You haven't said anything to her yet about last night, have you?" Mr. Franklin asked.

"No, sir."

"Then say nothing now. I had better not invite the girl's confidence, with the Sergeant on the look-out to surprise us together. My conduct is not very consistent, Betteredge - is it? I see no way out of this business, which isn't dreadful to think of, unless the Diamond is traced to Rosanna. And yet I can't, and won't, help Sergeant Cuff to find the girl out."
