Some aspects of this discrepancy are revealed by Lord Greystoke himself in “Extracts from the Memoirs of Lord Greystoke,” Mother Was a Lovely Beast, Philip José Farmer, editor, Chilton, October, 1974. However, this revelation is only a minor part of Watson’s chronicle, one among many mysteries solved, and this account presents the mystery from a somewhat different viewpoint.
Your editor decided for these reasons to leave this explanation in this work. Besides, your editor would not dream of tampering with any part of the Sacred Writings.

It is with a light heart that I take up my pen to write these the last words in which I shall ever record the singular genius which distinguished my friend Sherlock Holmes. I realise that I once wrote something to that effect, though at that time my heart was as heavy as it could possibly be. This time I am certain that Holmes has retired for the last time. At least, he has sworn that he will no more go a-detectiving. The case of the peerless peer has made him financially secure, and he foresees no more grave perils menacing our country now that out great enemy has been laid low. Moreover, he has sworn that never again will he set foot on any soil but that of his native land. Nor will he ever again get near an aircraft. The mere sight or sound of one freezes his blood.
The peculiar adventure which occupies these pages began on the second day of February, 1916. At this time I was, despite my age, serving on the staff of a military hospital in London. Zeppelins had made bombing raids over England for two nights previously, mainly in the Midlands. Though these were comparatively ineffective, seventy people had been killed, one hundred and thirteen injured, and a monetary damage of fifty-three thousand eight hundred and thirty-two pounds had been inflicted. These raids were the latest in a series starting the nineteenth of January. There was no panic, of course, but even stout British hearts were experiencing some uneasiness. There were rumours, no doubt originated by German agents, that the Kaiser intended to send across the channel a fleet of a thousand airships. I was discussing this rumour with my young friend, Dr. Fell, over a brandy in my quarters when a knock sounded on the door. I opened it to admit a messenger. He handed me a telegram which I wasted no time in reading.
“Great Scott!” I cried.
“What is it, my dear fellow?” Fell said, heaving himself from the chair. Even then, on war rations, he was putting on overly much weight.
“A summons to the F.O.,” I said. “From Holmes. And I am on special leave.”
“Sherlock?” said Fell.
“No, Mycroft,” I replied. Minutes later, having packed my few belongings, I was being driven in a limousine toward the Foreign Office. An hour later, I entered the small austere room in which the massive Mycroft Holmes sat like a great spider spinning the web that ran throughout the British Empire and many alien lands. There were two others present, both of whom I knew. One was young Merrivale, a baronet’s son, the brilliant aide to the head of the British Military Intelligence Department and soon to assume the chieftainship. He was also a qualified physician and had been one of my students when I was lecturing at Bart’s. Mycroft claimed that Merrivale was capable of rivalling Holmes himself in the art of detection and would not be far behind Mycroft himself. Holmes’ reply to this “needling” was that only practise revealed true promise.
I wondered what Merrivale was doing away from the War Office but had no opportunity to voice my question. The sight of the second person there startled me at the same time it delighted me. It had been over a year since I had seen that tall, gaunt figure with the greying hair and the unforgettable hawklike profile.
“My dear Holmes,” I said. “I had thought that after the Von Bork affair...”
“The east wind has become appallingly cold, Watson,” he said. “Duty recognises no age limits, and so I am called from my bees to serve our nation once more.”
Looking even more grim, he added, “The Von Bork business is not over. I fear that we underestimated the fellow because we so easily captured him. He is not always taken with such facility. Our government erred grievously in permitting him to return to Germany with Von Herling. He should have faced a firing squad. A motor-car crash in Germany after his return almost did for us what we had failed to do, according to reports that have recently reached me. But, except for a permanent injury to his left eye, he has recovered.
“Mycroft tells me that Von Bork has done, and is doing, us inestimable damage. Our intelligence tells us that he is operating in Cairo, Egypt. But just where in Cairo and what disguise he has assumed is not known.”
“The man is indeed dangerous,” Mycroft said, reaching with a hand as ponderous as a grizzly’s paw for his snuff-box. “It is no exaggeration to say that he is the most dangerous man in the world, as far as the Allies are concerned, anyway.”
“Greater than Moriarty was?” Holmes said, his eyes lighting up.
“Much greater,” replied Mycroft. He breathed in the snuff, sneezed, and wiped his jacket with a large red handkerchief. His watery grey eyes had lost their inward-turning look and burned as if they were searchlights probing the murkiness around a distant target.
“Von Bork has stolen the formula of a Hungarian refugee scientist employed by our government in Cairo. The scientist recently reported to his superiors the results of certain experiments he had been making on a certain type of bacillus peculiar to the land of the Pharaohs. He had discovered that this bacillus could be modified by chemical means to eat only sauerkraut. When a single bacillus was placed upon sauerkraut, it multiplied at a fantastic rate. It would become within sixty minutes a colony which would consume a pound of sauerkraut to its last molecule.
“You see the implications. The bacillus is what the scientists call a mutated type. After treatment with a certain chemical both its form and function are changed. Should we drop vials containing this mutation in Germany, or our agents directly introduce the germs, the entire nation would shortly become sauerkrautless. Both their food supply and their morale would be devastated.
“But Von Bork somehow got wind of this, stole the formula, destroyed the records and the chemicals with fire, and murdered the only man who knew how to mutate the bacillus.
“However, his foul deed was no sooner committed than detected. A tight cordon was thrown around Cairo, and we have reason to believe that Von Bork is hiding in the native quarter somewhere. We can’t keep that net tight for long, my dear Sherlock, and that is why you must be gotten there quickly so you can track him down. England expects much from you, brother, and much, I am sure, will be given.”
I turned to Holmes, who looked as shaken as I felt. “Surely, my dear fellow, we are not going to Cairo?”
“Surely indeed, Watson,” he replied. “Who else could sniff out the Teutonic fox, who else could trap him? We are not so old that we cannot settle Von Bork’s hash once and for all.”
Holmes, I observed, was still in the habit of using Americanisms, I suppose because he had thrown himself so thoroughly into the role of an Irish-American while tracking down Von Bork in that adventure which I have titled “His Last Bow.”
“Unless,” he said, sneering, “you really feel that the old warhorse should not leave his comfortable pasture?”
“I am as good a man as I was a year and a half ago,” I protested. “Have you ever known me to call it quits?”
