"At Rexton?" said Jennings impatiently, "yes, yes, go on."

"At a house near the railway station which I can point out, mother having seen it when she went to inquire."

"Inquire about what?"

"About father's secret job. He had one he used to go to for three hours every day by agreement with the foreman. Father was very clever and could do all sorts of things. Mother never knew what the job was, but father said it would make us all rich."

"Yes, go on." Jennings looked at her, nursing his chin.

"The other day I came across some papers," said Susan, taking a roll out of her pocket. "And it proved to be plans of father's secret job. And you might have knocked me down with a feather, Mr. Jennings, when I saw on the plans the name of Rose Cottage."

The detective jumped up, greatly excited. "Rose Cottage!" he cried, holding out his hands. "The plans—the plans!"

"I brought them, as I know Miss Saxon who now has Rose Cottage, is engaged to Mr. Mallow—"

"Haven't you got over that nonsense yet?" said Jennings, who was looking eagerly at the plans.

"Yes, I have," replied Miss Grant, confidentially. "I am engaged to a rising young baker who is just a foreman just now, but we hope to save and start a shop. Still, I promised to help Mr. Mallow, and I thought he would like to see those plans. You see, sir, they have to do with Rose Cottage."
