dagger. As to the former, I think I can give you the murderer’s name; but we had better take the evidence in order. You may remember,” he continued, “that when Dr. Jervis stood as if winding the clock, I chalked a mark on the floor where he stood. Now, standing on that marked spot, and looking out of the open window, I could see two of the windows of a house nearly opposite. They were the second- and third-floor windows of No. 6, Cotman Street. The second-floor is occupied by a firm of architects; the third-floor by a commission agent named Thomas Barlow. I called on Mr. Barlow, but before describing my visit, I will refer to another matter. You haven’t those threatening letters about you, I suppose?”
“Yes, I have,” said the inspector; and he drew forth a wallet from his breast-pocket.
“Lot us take the first one, then,” said Thorndyke. “You see that the paper and envelope are of the very commonest, and the writing illiterate. But the ink does not agree with this. Illiterate people usually buy their ink in penny bottles. Now, this envelope is addressed with Draper’s dichroic ink—a superior office ink, sold only in large bottles—and the red ink in which the note is written is an unfixed, scarlet ink, such as is used by draughtsmen, and has been used, as you can see, in a stylographic pen. But the most interesting thing about this letter is the design drawn at the top. In an artistic sense, the man could not draw, and the anatomical details of the skull are ridiculous. Yet the drawing is very neat. It has the clean, wiry line of a machine drawing, and is done with a steady, practised hand. It is also perfectly symmetrical; the skull, for instance, is exactly in the centre, and, when we examine it through a lens, we see why it is so, for we discover traces of a pencilled centre-line and ruled cross-lines. Moreover, the lens reveals a tiny particle of draughtsman’s soft, red, rubber, with which the pencil lines were taken out; and all these facts, taken together, suggest that the drawing was made by someone accustomed to making accurate mechanical drawings. And now we will return to Mr. Barlow. He was out when I called, but I took the liberty of glancing round the office, and this is what I saw. On the mantelshelf was a twelve-inch flat boxwood rule, such as engineers use, a piece of soft, red rubber, and a stone bottle of Draper’s dichroic ink. I obtained, by a simple ruse, a specimen of the office notepaper and the ink. We will examine it presently. I found that Mr. Barlow is a new tenant, that he is rather short, wears a wig and spectacles, and always wears a glove on his left hand. He left the office at 8.30 this morning, and no one saw him arrive. He had with him a square case, and a narrow, oblong one about five feet in length; and he took a cab to Victoria, and apparently caught the 8.51 train to Chatham.”
“Ah!” exclaimed the inspector.
“But,” continued Thorndyke, “now examine those three letters, and compare them with this note that I wrote in Mr. Barlow’s office. You see that the paper is of the same make, with the same water-mark, but that is of no great significance. What is of crucial importance is this: You see, in each of these letters, two tiny indentations near the bottom corner. Somebody has used compasses or drawing-pins over the packet of notepaper, and the points have made little indentations, which have marked several of the sheets. Now, notepaper is cut to its size after it is folded, and if you stick a pin into the top sheet of a section, the indentations on all the underlying sheets will be at exactly similar distances from the edges and corners of the sheet. But you see that these little dents are all at the same distance from the edges and the corner.” He demonstrated the fact with a pair of compasses. “And now look at this sheet, which I obtained at Mr. Barlow’s office. There are two little indentations—rather faint, but quite visible—near the bottom corner, and when we measure them with the compasses, we find that they are exactly the same distance apart as the others, and the same distance from the edges and the bottom corner. The irresistible conclusion is that these four sheets came from the same packet.”
The inspector started up from his chair, and faced Thorndyke. “Who is this Mr. Barlow?” he asked.
“That,” replied Thorndyke, “is for you to determine; but I can give you a useful hint. There is only one person who benefits by the death of Alfred Hartridge, but he benefits to the extent of twenty thousand pounds. His name is Leonard Wolfe, and I learn from Mr. Marchmont that he is a man of indifferent character—a gambler and a spendthrift. By profession he is an engineer, and he is a capable mechanician. In appearance he is thin, short, fair, and clean-shaven, and he has lost the middle finger of his left hand. Mr. Barlow is also short, thin, and fair, but wears a wig, a board, and spectacles, and always wears a glove on his left hand. I have seen the handwriting of both these gentlemen, and should say that it would be difficult to distinguish one from the other.”
“That’s good enough for me,” said the inspector. “Give me his address, and I’ll have Miss Curtis released at once.”
* * * *
The same night Leonard Wolfe was arrested at Eltham, in the very act of burying in his garden a large and powerful compressed-air rifle. He was never brought to trial, however, for he had in his pocket a more portable weapon—a large-bore Derringer pistol—with which he managed to terminate an exceedingly ill-spent life.
“And, after all,” was Thorndyke’s comment, when he heard of the event, “he had his uses. He has relieved society of two very bad men, and he has given us a most instructive case. He has shown us how a clever and ingenious criminal may take endless pains to mislead and delude the police, and yet, by inattention to trivial details, may scatter clues broadcast. We can only say to the criminal class generally, in both respects, ‘Go thou and do likewise.’”
A MESSAGE FROM THE DEEP SEA (1909)
The Whitechapel Road, though redeemed by scattered relics of a more picturesque past from the utter desolation of its neighbour the Commercial Road, is hardly a gay thoroughfare. Especially at its eastern end, where its sordid modernity seems to reflect the colourless lives of its inhabitants, does its grey and dreary length depress the spirits of the wayfarer. But the longest and dullest road can be made delightful by sprightly discourse seasoned with wit and wisdom, and so it was that, as I walked westward by the side of my friend John Thorndyke, the long, monotonous road seemed all too short.
We had been to the London Hospital to see a remarkable case of acromegaly, and, as we returned, we discussed this curious affection, and the allied condition of gigantism, in all their bearings, from the origin of the “Gibson chin” to the physique of Og, King of Bashan.
“It would have been interesting,” Thorndyke remarked as we passed up Aldgate High Street, “to have put one’s finger into His Majesty’s pituitary fossa—after his decease, of course. By the way, here is Harrow Alley; you remember Defoe’s description of the dead-cart waiting out here, and the ghastly procession coming down the alley.” He took my arm and led me up the narrow thoroughfare as far as the sharp turn by the “Star and Still” public-house, where we turned to look back.
“I never pass this place,” he said musingly, “but I seem to hear the clang of the bell and the dismal cry of the carter—”
He broke off abruptly. Two figures had suddenly appeared framed in the archway, and now advanced at headlong speed. One, who led, was a stout, middle-aged Jewess, very breathless and dishevelled; the other was a well-dressed young man, hardly less agitated than his companion. As they approached, the young man suddenly recognized my colleague, and accosted him in agitated tones.
“I’ve just been sent for to a case of murder or suicide. Would you mind looking at it for me, sir? It’s my first case, and I feel rather nervous.”
Here the woman darted back, and plucked the young doctor by the arm.
“Hurry! Hurry!” she exclaimed, “don’t stop to talk.” Her face was as white as lard, and shiny with sweat; her lips twitched, her hands shook, and she stared with the eyes of a frightened child.
