The Adventure of the Bruce-Partington Plans In the third week of November, in the year 1895, a dense yellow fog settled down upon London. From the Monday to the Thursday I doubt whether it was ever possible from our windows in Baker Street to see the loom of the opposite houses. The first day Holmes had spent in cross-indexing his huge book of references. The second and third had been patiently occupied upon a subject which he had recently made his hobby—the music of the Middle Ages. But when, for the fourth time, after pushing back our chairs from breakfast we saw the greasy, heavy brown swirl still drifting past us and condensing in oily drops upon the window-panes, my comrade’s impatient and active nature could endure this drab existence no longer. He paced restlessly about our sitting-room in a fever of suppressed energy, biting his nails, tapping the furniture, and chafing against inaction. “Nothing of interest in the paper, Watson?” he said. I was aware that by anything of interest, Holmes meant anything of criminal interest. There was the news of a revolution, of a possible war, and of an impending change of government; but these did not come within the horizon of my companion. I could see nothing recorded in the shape of crime which was not commonplace and futile. Holmes groaned and resumed his restless meanderings. “The London criminal is certainly a dull fellow,” said he in the querulous voice of the sportsman whose game has failed him. “Look out this window, Watson. See how the figures loom up, are dimly seen, and then blend once more into the cloud-bank. The thief or the murderer could roam London on such a day as the tiger does the jungle, unseen until he pounces, and then evident only to his victim.” “There have,” said I, “been numerous petty thefts.” Holmes snorted his contempt. “This great and sombre stage is set for something more worthy than that,” said he. “It is fortunate for this community that I am not a criminal.” “It is, indeed!” said I heartily. “Suppose that I were Brooks or Woodhouse, or any of the fifty men who have good reason for taking my life, how long could I survive against my own pursuit? A summons, a bogus appointment, and all would be over. It is well they don’t have days of fog in the Latin countries—the countries of assassination. By Jove! here comes something at last to break our dead monotony.” It was the maid with a telegram. Holmes tore it open and burst out laughing. “Well, well! What next?” said he. “Brother Mycroft is coming round.” “Why not?” I asked. “Why not? It is as if you met a tram-car coming down a country lane. Mycroft has his rails and he runs on them. His Pall Mall lodgings, the Diogenes Club, Whitehall—that is his cycle. Once, and only once, he has been here. What upheaval can possibly have derailed him?” “Does he not explain?” Holmes handed me his brother’s telegram. “Must see you over Cadogan West. Coming at once.” MYCROFT. “Cadogan West? I have heard the name.”
