One day when I was busy with my books and Mr. Pocket, I received a note by the post, the mere outside of which threw me into a great flutter; for, though I had never seen the handwriting in which it was addressed, I divined whose hand it was. It had no set beginning, as Dear Mr. Pip, or Dear Pip, or Dear Sir, or Dear Anything, but ran thus:--

     "I am to come to London the day after to-morrow by the midday coach. I believe it was settled you should meet me? At all events Miss Havisham has that impression, and I write in obedience to it. She sends you her regard.

     "Yours, ESTELLA."

     If there had been time, I should probably have ordered several suits of clothes for this occasion; but as there was not, I was fain to be content with those I had. My appetite vanished instantly, and I knew no peace or rest until the day arrived. Not that its arrival brought me either; for, then I was worse than ever, and began haunting the coach-office in Wood Street, Cheapside, before the coach had left the Blue Boar in our town. For all that I knew this perfectly well, I still felt as if it were not safe to let the coach-office be out of my sight longer than five minutes at a time; and in this condition of unreason I had performed the first half-hour of a watch of four or five hours, when Wemmick ran against me.
