“What is it?”

“Your card.”

“My card?”

“You have just told me not to be uneasy,” said the old lady. “I am uneasy, for all that. I don’t feel as sure as you do that this woman really is in the grounds. She may be lurking somewhere in the house, and she may appear when your back in turned. Remember what you told me.”

Julian understood the allusion. He made no reply.

“The people at the police station close by,” pursued Lady Janet, “have instructions to send an experienced man, in plain clothes, to any address indicated on your card the moment they receive it. That is what you told me. For Grace’s protection, I want your card before you leave us.”

It was impossible for Julian to mention the reasons which now forbade him to make use of his own precautions—in the very face of the emergency which they had been especially intended to meet. How could he declare the true Grace Roseberry to be mad? How could he give the true Grace Roseberry into custody? On the other hand, he had personally pledged himself (when the circumstances appeared to require it) to place the means of legal protection from insult and annoyance at his aunt’s disposal. And now, there stood Lady Janet, unaccustomed to have her wishes disregarded by anybody, with her band extended, waiting for the card!

What was to be done? The one way out of the difficulty appeared to be to submit for the moment. If he succeeded in discovering the missing woman, he could easily take care that she should be subjected to no needless indignity. If she contrived to slip into the house in his absence, he could provide against that contingency by sending a second card privately to the police station, forbidding the officer to stir in the affair until he had received further orders. Julian made one stipulation only before he handed his card to his aunt.

“You will not use this, I am sure, without positive and pressing necessity,” he said. “But I must make one condition. Promise me to keep my plan for communicating with the police a strict secret—”

“A strict secret from Grace?” interposed Lady Janet. (Julian bowed.) “Do you suppose I want to frighten her? Do you think I have not had anxiety enough about her already? Of course I shall keep it a secret from Grace!”
