"Who is to decide when she needs me?"

"I am to decide," Mrs. Vimpany answered; "Iris writes to me confidentially. If anything happens which she may be unwilling to trust to a letter, I believe I shall hear of it from her maid."

"Are you sure the maid is to be relied on?" Mountjoy interposed.

"She is a silent creature, so far as I know anything of her," Mrs. Vimpany admitted; "and her manner doesn't invite confidence. But I have spoken with Fanny Mere; I am satisfied that she is true to her mistress and grateful to her mistress in her own strange way. If Iris is in any danger, I shall not be left in ignorance of it. Does this incline you to consult with me, before you decide on going to Paris? Don't stand on ceremony; say honestly, Yes or No."

Honestly, Hugh said Yes.

He was at once trusted with the address of Iris. At the same time, Mrs. Vimpany undertook that he should know what news she received from Paris as soon as she knew it herself. On that understanding they parted, for the time being.
