“Lor’, but it gave me a turn, Mr. Holmes. If I hadn’t turned back, I might never have seen him, and who knows but that he’s been following me ever since I’ve met him? It ain’t right for a cove you’ve been following to follow you that way. I dived out of that doorway with my heart pounding in my ears and the chiv you gave me in my hand, and I cut across Great Garden Street to Whitechapel Road, and I didn’t stop running till I’d reached that great mob riot of a station across from the hospital.”

My friend pulled a telegraph form out of a drawer. “Miss Monk, does Stephen Dunlevy know where you reside?”

“He’s seen me go in often enough.”

“Has he ever caught sight of you tailing him, to your knowledge?”

“I’d have sworn he hadn’t this morning, but I’d sound a proper flat, saying such a thing now.”

“Miss Monk, I give you my word that I never expected Dunlevy to do anything so precipitate as to dog your movements, but I admit that I have long suspected him of being more than meets the eye.”

“Well, that’s clear enough!” I scowled. “What business would a common soldier have trailing Miss Monk?”

“He’s no soldier,” said Holmes and Miss Monk, very nearly at the same time.

“What?” I cried. My companions eyed each other warily.

“Well, one or the other of you is going to have to make clear to me why he is not a soldier,” I declared in exasperation.

The replies, “His stride” and “His pocket handkerchief,” once more vied for my attention.

Holmes cleared his throat. “Every serviceman who’s been in more than a fortnight’s time carries his pocket handkerchief in his sleeve, not in his coat pocket,” he explained. “You do so yourself, my dear fellow. You were saying, Miss Monk?”

“Oh, I—that is to say, I noticed where he kept his billy when you asked after it, Mr. Holmes—but in any case soldiers don’t walk that way. Least none I’ve ever laid eyes on. Not even orderlies.”

“Very well, then,” I said testily. “Leaving aside what Stephen Dunlevy is not, may I inquire what he, in fact, is?”

“You will both know as much as I do tomorrow,” Holmes stated firmly. “This telegram will settle the matter for good or ill. I am happy to say that few shadows remain to confound us, but if you would both agree to meet here at three o’clock tomorrow afternoon, all will be made clear to you then. Miss Monk, have you any objection to continuing your use of the underground just for the day?”

“I may have a pound a week, but I’m not such a lady as all that.”

“And would it trouble you to sleep away from your rooms tonight? I’ve an address where you will be well looked after.” Holmes handed her a card. “It is entirely a matter of precaution, but I would prefer if you weren’t left to fend for yourself. My friend has an amiable housekeeper and an extra room.”

“‘Mr. George Lusk, One Tollet Street, Alderney Road…,’” she read. “It’s all one to me. Nearly everything I need’s in my pockets. But what happens tomorrow?”

Holmes smiled as he led her to the door. “I look forward to tomorrow with the greatest interest. In the meanwhile, Miss Monk, you’ll be in safe hands. I’m terribly sorry you were startled, but I’ve the greatest respect for your fortitude throughout this inquiry, you must know.”

Miss Monk flushed slightly pink at his words. “If I’m to suffer no more than a few trips on the underground, it’s worth my time. Until tomorrow, then, gents. I suppose this Mr. Lusk will be surprised to see me? Well, no matter. I’ll make him used to the idea soon enough.”

The following afternoon at half past two, I sat alone smoking a cigar with an issue of the Lancet on my knee, attempting with negligible success to follow the thread of reasoning in an article concerning parasitic ailments. At ten to the hour, I stoked the fire and peered out the bow window for signs of life. Finally I heard Holmes’s catlike tread upon the stairs, and my friend entered, laughing silently to himself.

“It is quite too perfect,” said he. “I could never have imagined it falling into place so—mind you, I’d no notion he was dogging her before yesterday, but it plays into our hand beautifully. Halloa—there’s the bell! Miss Monk has arrived.”

Miss Monk appeared in far better spirits than she had the day before. She greeted us cheerfully and, catching sight of her hair in the reflection of the sideboard, feigned a scowl and attempted to wrest it into submission.

“Them small ones Mr. Lusk is left with are a sight too much for one girl to take on,” she remarked contentedly, pulling a pin out of one of her pockets. “Though the older four don’t plague you half as much as the younger three. I’ve been a princess, a maharaja’s slave girl, a genie, and a pack horse since I arrived last night, so if I can stay awake long enough to—” She interrupted herself at the ringing of the downstairs bell.

“Miss Monk, if you would take the basket chair,” Holmes suggested. “Dr. Watson, in your usual place, and we’ll leave the whole expanse of the sofa for our guest’s comfort.”

I do not know what I had expected when the door swung open, but the tall, fair, broad-shouldered young fellow, dressed in quiet check trousers and a coat of dark grey, appeared in the worst state of contained agitation. His pleasant features, clean shaven save for an upturned moustache, were marred by a terrible apprehension. In the gleaming light of afternoon, for an instant I was unable to place him, but in a flash I recognized the young man Miss Monk had met for drinks at the Queen’s Head on that night of abominable memory.

“Mr. Stephen Dunlevy, I presume,” the detective declared. “My name is Sherlock Holmes, although I flatter myself you are already aware of it. Dr. Watson you will likewise recall, and I know you have had the pleasure of Miss Monk’s company on numerous occasions.”

Stephen Dunlevy, who had appeared not in the least surprised to see Sherlock Holmes awaiting him, gave an unabashed cry of relief at the sight of Miss Monk, whose expressive brows were aloft in surprise.

“What ho, Dunlevy,” she said at length. “You’ve had a wash since last I saw you, at any rate.”

Our guest appeared deeply taken aback by this remark, but Holmes, as ever, was in control of the room.

“Pray sit down, Mr. Dunlevy,” my friend requested. “I am pleased to say your presence here confirms the opinion I had formed of you. Perhaps you would be so good as to answer any little questions we may care to pose.”

“Certainly, sir. Since your summons, I hardly know what has happened.”

Sherlock Holmes smiled enigmatically. “I fancy I can describe the chain of events to you. There are, of course, one or two trifling details I require you to supply.”

“I am at your service, so glad am I to see Miss Monk here at Baker Street.”

Miss Monk and I exchanged puzzled looks at this, but Holmes continued unperturbed.

“I am glad to hear it. At the outset I was unsure whether you were a City plainclothesman or a private detective, but I am now pleased to introduce you to Miss Monk and Dr. Watson as one Stephen Dunlevy, journalist at the Star, that seething hotbed of liberal disaffection.”

I drew a sharp breath in surprise. “A journalist! Then what of this tale of the lost cohort and the murdered girl?”

“Ah, there’s the crux of the matter,” said Holmes, lighting a cigarette complacently. “I shall begin at the beginning, and just interrupt me if there are any points which are not clear.

“Stephen Dunlevy, for he has been using his real name, earns his bread and cheese by writing those incendiary social articles that my brother recently had reason to bemoan in these very rooms. There is a living to be made by exposing the shambles of British civilization known as Whitechapel, and for the more audacious members of the press, it is not unheard of to investigate in disguise if a better story is to be gained.
