"Just what your mother would have done. Your mother would have argued like this: Either Sissie is staying away against her will or she is staying away of her own accord. If the former, it means an accident, and we are bound to hear shortly from one of the hospitals. If the latter, we can only sit tight. Your mother had a vigorous mind and that is how she would have looked at things."

"I never know how to take you, Arthur," said Mrs. Prohack, and went on: "And what makes it all the more incomprehensible is that yesterday afternoon Sissie went with me to Jay's to see about the wedding-dress."

"But why should that make it all the more incomprehensible?"

"Don't you think it does, somehow? I do."

"Did she giggle at Jay's?"

"Oh, no! Except once. Yes, I think she giggled once. That was when the fitter said she hoped we should give them plenty of time, because most customers rushed them so. I remember thinking how queer it was that Sissie should laugh so much at a perfectly simple remark like that. Oh! Arthur!"

"Now, my child," said Mr. Prohack firmly. "Don't get into your head that Sissie has gone off hers. Yesterday you thought for quite half an hour that I was suffering from incipient lunacy. Let that suffice you for the present. Be philosophical. The source of tranquillity is within. Remember that, and remind me of it too, because I'm apt to forget it.... We can do nothing at the moment. I will now get up, and I warn you that I shall want a large breakfast and you to pour out my coffee and read the interesting bits out of The Daily Picture to me."

At eleven o'clock of the morning the status quo was still maintaining itself within the noble mansion at Manchester Square. Mr. Prohack, washed, dressed, and amply fed, was pretending to be very busy with correspondence in his study, but he was in fact much more busy with Eve than with the correspondence. She came in to him every few minutes, and each time needed more delicate handling. After one visit Mr. Prohack had an idea. He transferred the key from the inside to the outside of the door. At the next visit Eve presented an ultimatum. She said that Mr. Prohack must positively do something about his daughter. Mr. Prohack replied that he would telephone to his solicitors: a project which happily commended itself to Eve, though what his solicitors could do except charge a fee Mr. Prohack could not imagine.

"You wait here," said he persuasively.
