It was brutally put; but it was true—doubly true, after the opening of Miss Gwilt’s letter. Mrs. Milroy gave way.

“What do you want to know?” she asked. “Tell me, and leave me.”

“I want to know what you are writing to Mr. Armadale about?”

“About Miss Gwilt.”

“What has Mr. Armadale to do with you and Miss Gwilt?”

Mrs. Milroy held up the letter that had been returned to her by the authorities at the Post-office.

“Stoop,” she said. “Miss Gwilt may be listening at the door. I’ll whisper.”

The nurse stooped, with her eye on the door. “You know that the postman went with this letter to Kingsdown Crescent?” said Mrs. Milroy. “And you know that he found Mrs. Mandeville gone away, nobody could tell where?”

“Well,” whispered Rachel “what next?”

“This, next. When Mr. Armadale gets the letter that I am going to write to him, he will follow the same road as the postman; and we’ll see what happens when he knocks at Mrs. Mandeville’s door.”
