Whilst seated by the window, and looking out upon the crowded street, with every now and then the strange scene in the grave-yard vividly before him, Mr. Green thought of the book he had been reading, and, remembering that he had left it on the tomb, where he had suddenly dropped it when called to the assistance of the lady, he immediately determined to return in search of it. After a walk of some twenty minutes, he was again over the spot where he had been an hour before, and from which he had been so unceremoniously expelled by the old man. He looked in vain for the book; it was no where to be found: nothing save a bouquet which the lady had dropped, and which lay half-buried in the grass from having been trodden upon, indicated that any one had been there that evening. Mr. Green took up the bunch of flowers, and again returned to the hotel. After passing a sleepless night, and hearing the clock strike six, he dropped into a sweet sleep, from which he did not awake until roused by the rap of a servant, who, entering his room, handed him a note which ran as follows:--"Sir,--I owe you an apology for the inconveniences to which you were subjected last evening, and if you will honour us with your presence to dinner to-day at four o'clock, I shall be most happy to give you due satisfaction. My servant will be in waiting for you at half-past three. I am, sir, your obedt. servant, J. Devenant. October 23, to George Green, Esq." The servant who handed this note to Mr. Green, informed him that the bearer was waiting for a reply. He immediately resolved to accept the invitation, and replied accordingly. Who this person was, and how his name and the hotel where he was stopping had been found out, was indeed a mystery. However, he waited impatiently for the hour when he was to see this new acquaintance, and get the mysterious meeting in the grave-yard solved.
