“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.”
