"When shall you send your invitations?"

"This very day."

"Well, I will immediately call on M. Danglars, and tell him that my mother and myself must leave Paris to-morrow. I have not seen you, consequently I know nothing of your dinner."

"How foolish you are! Have you forgotten that M. Debray has just seen you at my house?"

"Ah, true,"

"Fix it this way. I have seen you, and invited you without any ceremony, when you instantly answered that it would be impossible for you to accept, as you were going to Treport."

"Well, then, that is settled; but you will come and call on my mother before to-morrow?"

"Before to-morrow? -- that will be a difficult matter to arrange, besides, I shall just be in the way of all the preparations for departure."

"Well, you can do better. You were only a charming man before, but, if you accede to my proposal, you will be adorable."

"What must I do to attain such sublimity?"

"You are to-day free as air -- come and dine with me; we shall be a small party -- only yourself, my mother, and I. You have scarcely seen my mother; you shall have an opportunity of observing her more closely. She is a remarkable woman, and I only regret that there does not exist another like her, about twenty years younger; in that case, I assure you, there would very very soon be a Countess and Viscountess of Morcerf. As to my father, you will not see him; he is officially engaged, and dines with the chief referendary. We will talk over our travels; and you, who have seen the whole world, will relate your adventures -- you shall tell us the history of the beautiful Greek who was with you the other night at the Opera, and whom you call your slave, and yet treat like a princess. We will talk Italian and Spanish. Come, accept my invitation, and my mother will thank you."

"A thousand thanks," said the count, "your invitation is most gracious, and I regret exceedingly that it is not in my power to accept it. I am not so much at liberty as you suppose; on the contrary, I have a most important engagement."

"Ah, take care, you were teaching me just now how, in case of an invitation to dinner, one might creditably make an excuse. I require the proof of a pre-engagement. I am not a banker, like M. Danglars, but I am quite as incredulous as he is."

"I am going to give you a proof," replied the count, and he rang the bell.

"Humph," said Morcerf, "this is the second time you have refused to dine with my mother; it is evident that you wish to avoid her." Monte Cristo started. "Oh, you do not mean that," said he; "besides, here comes the confirmation of my assertion." Baptistin entered, and remained standing at the door. "I had no previous knowledge of your visit, had I?"

"Indeed, you are such an extraordinary person, that I would not answer for it."

"At all events, I could not guess that you would invite me to dinner."

"Probably not."

"Well, listen, Baptistin, what did I tell you this morning when I called you into my laboratory?"

"To close the door against visitors as soon as the clock struck five," replied the valet.

“Is he your junior?”

“Seven years my senior.”

“How comes it that he is unknown?”

“Oh, he is very well known in his own circle.”

“Where, then?”

“Well, in the Diogenes Club, for example.”

I had never heard of the institution, and my face must have proclaimed as much, for Sherlock Homes pulled out his watch.

“The Diogenes Club is the queerest club in London, and Mycroft one of the queerest men. He’s always there from quarter to five to twenty to eight. It’s six now, so if you care for a stroll this beautiful evening I shall be very happy to introduce you to two curiosities.”

Five minutes later we were in the street, walking towards Regent’s Circus.

“You wonder,” said my companion, “why it is that Mycroft does not use his powers for detective work. He is incapable of it.”

“But I thought you said —”

“I said that he was my superior in observation and deduction. If the art of the detective began and ended in reasoning from an armchair, my brother would be the greatest criminal agent that ever lived. But he has no ambition and no energy. He will not even go out of his way to verify his own solutions, and would rather be considered wrong than take the trouble to prove himself right. Again and again I have taken a problem to him, and have received an explanation which has afterwards proved to be the correct one. And yet he was absolutely incapable of working out the practical points which must be gone into before a case could be laid before a judge or jury.”

“It is not his profession, then?”

“By no means. What is to me a means of livelihood is to him the merest hobby of a dilettante. He has an extraordinary faculty for figures, and audits the books in some of the government departments. Mycroft lodges in Pall Mall, and he walks round the corner into Whitehall every morning and back every evening. From year’s end to year‘s end he takes no other exercise, and is seen nowhere else, except only in the Diogenes Club, which is just opposite his rooms.”

“I cannot recall the name.”

“Very likely not. There are many men in London, you know, who, some from shyness, some from misanthropy, have no wish for the company of their fellows. Yet they are not averse to comfortable chairs and the latest periodicals. It is for the convenience of these that the Diogenes Club was started, and it now contains the most unsociable and unclubable men in town. No member is permitted to take the least notice of any other one. Save in the Stranger’s Room, no talking is, under any circumstances, allowed, and three offences, if brought to the notice of the committee, render the talker liable to expulsion. My brother was one of the founders, and I have myself found it a very soothing atmosphere.”

We had reached Pall Mall as we talked, and were walking down it from the St. James’s end. Sherlock Holmes stopped at a door some little distance from the Carlton, and, cautioning me not to speak, he led the way into the hall. Through the glass panelling I caught a glimpse of a large and luxurious room, in which a considerable number of men were sitting about and reading papers, each in his own little nook. Holmes showed me into a small chamber which looked out into Pall Mall, and then, leaving me for a minute, he came back with a companion whom I knew could only be his brother.
