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.

CHAPTER XIX

The news of Rosanna’s disappearance had, as it appeared, spread among the out-of-door servants. They too had made their inquiries; and they had just laid hands on a quick little imp, nicknamed “Duffy”—who was occasionally employed in weeding the garden, and who had seen Rosanna Spearman as lately as half-an-hour since. Duffy was certain that the girl had passed him in the fir-plantation, not walking, but running, in the direction of the sea-shore.

“Does this boy know the coast hereabouts?” asked Sergeant Cuff.
