to pursue their investigations to the end. Truth is stranger than fiction, and has need to be, since most fiction is founded on truth. There is a strangeness in the story of "The Man Who Knew" which brings it into the category of veracious history. It cannot be said in truth that any story begins at the beginning of the first chapter, since all stories began with the creation of the world, but this present story may be said to begin when we cut into the lives of some of the characters concerned, upon the seventeenth day of July, 19—.
There was a little group of people about the prostrate figure of a man who lay upon the sidewalk in Gray Square, Bloomsbury.
The hour was eight o'clock on a warm summer evening, and that the unusual spectacle attracted only a small crowd may be explained by the fact that Gray Square is a professional quarter given up to the offices of lawyers, surveyors, and corporation offices which at eight o'clock on a summer's day are empty of occupants. The unprofessional classes who inhabit the shabby streets impinging upon the Euston Road do not include Gray Square in their itinerary when they take their evening constitutionals abroad, and even the loud children find a less depressing environment for their games.
The gray-faced youth sprawled upon the pavement was decently dressed and was obviously of the superior servant type.
He was as obviously dead.
Death, which beautifies and softens the plainest, had failed entirely to dissipate the impression of meanness in the face of the stricken man. The lips were set in a little sneer, the half-closed eyes were small, the clean-shaven jaw was long and underhung, the ears were large and grotesquely prominent.
A constable stood by the body, waiting for the arrival of the ambulance, answering in monosyllables the questions of the curious. Ten minutes before the ambulance arrived there joined the group a man of middle age.
He wore the pepper-and-salt suit which distinguishes the country excursionist taking the day off in London. He had little side whiskers and a heavy brown mustache. His golf cap was new and set at a somewhat rakish angle on his head. Across his waistcoat was a large and heavy chain hung at intervals with small silver medals. For all his provincial appearance his movements were decisive and suggested authority. He elbowed his way through the little crowd, and met the constable's disapproving stare without faltering.
"Can I be of any help, mate?" he said, and introduced himself as Police Constable Wiseman, of the Sussex constabulary.
The London constable thawed.
"Thanks," he said; "you can help me get him into the ambulance when it comes."
"Fit?" asked the newcomer.
The policeman shook his head.
"He was seen to stagger and fall, and by the time I arrived he'd snuffed out. Heart disease, I suppose."
"Ah!" said Constable Wiseman, regarding the body with a proprietorial and professional eye, and retailed his own experiences of similar tragedies, not without pride, as though he had to some extent the responsibility for their occurrence.
On the far side of the square a young man and a girl were walking slowly. A tall, fair, good-looking youth he was, who might have attracted attention even in a crowd. But more likely would that attention have been focused, had he been accompanied by the girl at his side, for she was by every standard beautiful. They reached the corner of Tabor Street, and it was the fixed and eager stare of a little man who stood on the corner of the street and the intensity of his gaze which first directed their attention to the tragedy on the opposite side of the square.
The little man who watched was dressed in an ill-fitting frock coat, trousers which seemed too long, since they concertinaed over his boots, and a glossy silk hat set at the back of his head.
"What a funny old thing!" said Frank Merrill under his breath, and the girl smiled.
The object of their amusement turned sharply as they came abreast of him. His freckled, clean-shaven face looked strangely old, and the big, gold-rimmed spectacles bridged halfway down his nose added to his ludicrous appearance. He raised his eyebrows and surveyed the two young people.
"There's an accident over there," he said briefly and without any preliminary.
"Indeed," said the young man politely.
"There have been several accidents in Gray Square," said the strange old man meditatively. "There was one in 1875, when the corner house—you can see the end of it from here—collapsed and buried fourteen people, seven of whom were killed, four of whom were injured for life, and three of whom escaped with minor injuries."
He said this calmly and apparently without any sense that he was acting at all unconventionally in volunteering the information, and went on:
"There was another accident in 1881, on the seventeenth of October, a collision between two hansom cabs which resulted in the death of a driver whose name was Samuel Green. He lived at 14 Portington Mews, and had a wife and nine children."
The girl looked at the old man with a little apprehension, and Frank Merrill laughed.
"You have a very good memory for this kind of thing. Do you live here?" he asked.
"Oh, no!" The little man shook his head vigorously.
He was silent for a moment, and then:
"I think we had better go over and see what it is all about," he said with a certain gravity.
His assumption of leadership was a little staggering, and Frank turned to the girl.
"Do you mind?" he asked.
She shook her head, and the three passed over the road to the little group just as the ambulance came jangling into the square. To Merrill's surprise, the policeman greeted the little man respectfully, touching his helmet.
"I'm afraid nothing can be done, sir. He is—gone."
"Oh, yes, he's gone!" said the other quite calmly.
He stooped down, turned back the man's coat, and slipped his hand into the inside pocket, but drew blank; the pocket was empty. With an extraordinary rapidity of movement, he continued his search, and to the astonishment of Frank Merrill the policeman did not deny his right. In the top left-hand pocket of the waistcoat he pulled out a crumpled slip which proved to be a newspaper clipping.
"Ah!" said the little man. "An advertisement for a manservant cut out of this morning's Daily Telegraph; I saw it myself. Evidently a manservant who was on his way to interview a new employer. You see: 'Call at eight-thirty at Holborn Viaduct Hotel.' He was taking a short cut when his illness overcame him. I know who is advertising for the valet," he added gratuitously; "he is a Mr. T. Burton, who is a rubber factor from Penang. Mr. T. Burton married the daughter of the Reverend George Smith, of Scarborough, in 1889, and has four children, one of whom is at Winchester. Hum!"
He pursed his lips and looked down again at the body; then suddenly he turned to Frank Merrill.
"Do you know this man?" he demanded.
Frank looked at him in astonishment.
"No. Why do you ask?"
"You were looking at him as though you did," said the little man. "That is to say, you were not looking at his face. People who do not look at other people's faces under these circumstances know them."
"Curiously enough," said Frank, with a little smile, "there is
