"Mile championship, 1880; Cortis won the other three, though."

"Yes, so he did. I saw Cortis when he first broke the old 2.46 mile record." And straightway Hewitt plunged into a whirl of talk of bicycles, tricycles, records, racing cyclists, Hillier, and Synyer and Noel Whiting, Taylerson and Appleyard--talk wherein the young man opposite bore an animated share, while I was left in the cold.

Our new friend, it seems, had himself been a prominent racing bicyclist a few years back, and was presently, at Hewitt's request, exhibiting a neat gold medal that hung at his watch-guard. That was won, he explained, in the old tall bicycle days, the days of bad tracks, when every racing cyclist carried cinder scars on his face from numerous accidents. He pointed to a blue mark on his forehead, which, he told us, was a track scar, and described a bad fall that had cost him two teeth, and broken others. The gaps among his teeth were plain to see as he smiled.

Presently the waiter brought dessert, and the young man opposite took an apple. Nut-crackers and a fruit-knife lay on our side of the stand, and Hewitt turned the stand to offer him the knife.

"No, thanks," he said; "I only polish a good apple, never peel it. It's a mistake, except with thick-skinned foreign ones."

And he began to munch the apple as only a boy or a healthy athlete can.

Presently he turned his head to order coffee. The waiter's back was turned, and he had to be called twice. To my unutterable amazement Hewitt reached swiftly across the table, s.n.a.t.c.hed the half-eaten apple from the young man's plate and pocketed it, gazing immediately, with an abstracted air, at a painted Cupid on the ceiling.

Our neighbor turned again, looked doubtfully at his plate and the table-cloth about it, and then shot a keen glance in the direction of Hewitt. He said nothing, however, but took his coffee and his bill, deliberately drank the former, gazing quietly at Hewitt as he did it, paid the latter, and left.

Immediately Hewitt was on his feet and, taking an umbrella, which stood near, followed. Just as he reached the door he met our late neighbor, who had turned suddenly back.

"Your umbrella, I think?" Hewitt asked, offering it.

"Yes, thanks." But the man's eye had more than its former hardness, and his jaw muscles tightened as I looked. He turned and went. Hewitt came back to me. "Pay the bill," he said, "and go back to your rooms; I will come on later. I must follow this man--it's the Foggatt case." As he went out I heard a cab rattle away, and immediately after it another.

I paid the bill and went home. It was ten o'clock before Hewitt turned up, calling in at his office below on his way up to me.

"Mr. Sidney Mason," he said, "is the gentleman the police will be wanting to-morrow, I expect, for the Foggatt murder. He is as smart a man as I remember ever meeting, and has done me rather neatly twice this evening."

"You mean the man we sat opposite at Luzatti's, of course?"

"Yes, I got his name, of course, from the reverse of that gold medal he was good enough to show me. But I fear he has bilked me over the address.

He suspected me, that was plain, and left his umbrella by way of experiment to see if I were watching him sharply enough to notice the circ.u.mstance, and to avail myself of it to follow him. I was hasty and fell into the trap. He cabbed it away from Luzatti's, and I cabbed it after him. He has led me a pretty dance up and down London to-night, and two cabbies have made quite a stroke of business out of us. In the end he entered a house of which, of course, I have taken the address, but I expect he doesn't live there. He is too smart a man to lead me to his den; but the police can certainly find something of him at the house he went in at--and, I expect, left by the back way. By the way, you never guessed that simple little puzzle as to how I found that this _was_ a murder, did you? You see it now, of course?"

"Something to do with that apple you stole, I suppose?"

"Something to do with it? I should think so, you worthy innocent. Just ring your bell; we'll borrow Mrs. Clayton's sewing-machine oil again. On the night we broke into Foggatt's room you saw the nutsh.e.l.ls and the bitten remains of an apple on the sideboard, and you remembered it; and yet you couldn't see that in that piece of apple possibly lay an important piece of evidence. Of course I never expected you to have arrived at any conclusion, as I had, because I had ten minutes in which to examine that apple, and to do what I did with it. But, at least, you should have seen the possibility of evidence in it.

"First, now, the apple was white. A bitten apple, as you must have observed, turns of a reddish brown color if left to stand long. Different kinds of apples brown with different rapidities, and the browning always begins at the core. This is one of the twenty thousand tiny things that few people take the trouble to notice, but which it is useful for a man in my position to know. A russet will brown quite quickly. The apple on the sideboard was, as near as I could tell, a Newtown pippin or other apple of that kind, which will brown at the core in from twenty minutes to half an hour, and in other parts in a quarter of an hour more. When we saw it, it was white, with barely a tinge of brown about the exposed core. Inference, somebody had been eating it fifteen or twenty minutes before, perhaps a little longer--an inference supported by the fact that it was only partly eaten.

"I examined that apple, and found it bore marks of very irregular teeth.

While you were gone, I oiled it over, and, rushing down to my rooms, where I always have a little plaster of Paris handy for such work, took a mold of the part where the teeth had left the clearest marks. I then returned the apple to its place for the police to use if they thought fit. Looking at my mold, it was plain that the person who had bitten that apple had lost two teeth, one at top and one below, not exactly opposite, but nearly so. The other teeth, although they would appear to have been fairly sound, were irregular in size and line. Now, the dead man had, as I saw, a very excellent set of false teeth, regular and sharp, with none missing.

Therefore it was plain that somebody _else_ had been eating that apple. Do I make myself clear?"

"Quite! Go on!"

"There were other inferences to be made--slighter, but all pointing the same way. For instance, a man of Foggatt's age does not, as a rule, munch an unpeeled apple like a school-boy. Inference, a young man, and healthy.

Why I came to the conclusion that he was tall, active, a gymnast, and perhaps a sailor, I have already told you, when we examined the outside of Foggatt's window. It was also pretty clear that robbery was not the motive, since nothing was disturbed, and that a friendly conversation had preceded the murder--witness the drinking and the eating of the apple.

Whether or not the police noticed these things I can't say. If they had had their best men on, they certainly would, I think; but the case, to a rough observer, looked so clearly one of accident or suicide that possibly they didn't.

"As I said, after the inquest I was unable to devote any immediate time to the case, but I resolved to keep my eyes open. The man to look for was tall, young, strong and active, with a very irregular set of teeth, a tooth missing from the lower jaw just to the left of the center, and another from the upper jaw a little farther still toward the left. He might possibly be a person I had seen about the premises (I have a good memory for faces), or, of course, he possibly might not.

"Just before you returned from your holiday I noticed a young man at Luzatti's whom I remembered to have seen somewhere about the offices in this building. He was tall, young, and so on, but I had a client with me, and was unable to examine him more narrowly; indeed, as I was not exactly engaged on the case, and as there are several tall young men about, I took little trouble. But to-day, finding the same young man with a vacant seat opposite him, I took the opportunity of making a closer acquaintance."

"You certainly managed to draw him out."

"Oh, yes; the easiest person in the world to draw out is a cyclist. The easiest cyclist to draw out is, of course, the novice, but the next easiest is the veteran. When you see a healthy, well-trained-looking man, who, nevertheless, has a slight stoop in the shoulders, and, maybe, a medal on his watch-guard, it is always a safe card to try him first with a little cycle-racing talk. I soon brought Mr. Mason out of his sh.e.l.l, read his name on his medal, and had a chance of observing his teeth--indeed, he spoke of them himself. Now, as I observed just now, there are several tall, athletic young men about, and also there are several men who have lost teeth. But now I saw that this tall and athletic young man had lost exactly _two_ teeth--one from the lower jaw, just to the left of the center, and another from the upper jaw, farther still toward the left!

Trivialities, pointing in the same direction, became important considerations. More, his teeth were irregular throughout, and, as nearly as I could remember it, looked remarkably like this little plaster mold of mine."

He produced from his pocket an irregular lump of plaster, about three inches long. On one side of this appeared in relief the likeness of two irregular rows of six or eight teeth, minus one in each row, where a deep gap was seen, in the position spoken of by my friend. He proceeded:

"This was enough at least to set me after this young man. But he gave me the greatest chance of all when he turned and left his apple (eaten unpeeled, remember!--another important triviality) on his plate. I'm afraid I wasn't at all polite, and I ran the risk of arousing his suspicions, but I couldn't resist the temptation to steal it. I did, as you saw, and here it is."

He brought the apple from his coat-pocket. One bitten side, placed against the upper half of the mold, fitted precisely, a projection of apple filling exactly the deep gap. The other side similarly fitted the lower half.

"There's no getting behind that, you see," Hewitt remarked. "Merely observing the man's teeth was a guide, to some extent, but this is as plain as his signature or his thumb impression. You'll never find two men _bite_ exactly alike, no matter whether they leave distinct teeth-marks or not. Here, by the by, is Mrs. Clayton's oil. We'll take another mold from this apple, and compare _them_."

He oiled the apple, heaped a little plaster in a newspaper, took my water-jug, and rapidly pulled off a hard mold. The parts corresponding to the merely broken places in the apple were, of course, dissimilar; but as to the teeth-marks, the impressions were identical.

"That will do, I think," Hewitt said. "Tomorrow morning, Brett, I shall put up these things in a small parcel, and take them round to Bow Street."

"But are they sufficient evidence?"

"Quite sufficient for the police purpose. There is the man, and all the rest--his movements on the day and so forth--are simple matters of inquiry; at any rate, that is police business."

I had scarcely sat down to my breakfast on the following morning when Hewitt came into the room and put a long letter before me.

"From our friend of last night," he said; "read it."

This letter began abruptly, and undated, and was as follows:

"TO MARTIN HEWITT, ESQ.

"SIR: I must compliment you on the adroitness you exhibited this evening in extracting from me my name. The address I was able to balk you of for the time being, although by the time you read this you will probably have found it through the _Law List_, as I am an admitted solicitor. That, however, will be of little use to you, for I am removing myself, I think, beyond the reach even of your abilities of search. I knew you well by sight, and was, perhaps, foolish to allow myself to be drawn as I did.

Still, I had no idea that it would be dangerous, especially after seeing you, as a witness with very little to say, at the inquest upon the scoundrel I shot. Your somewhat discourteous seizure of my apple at first amazed me--indeed, I was a little doubtful as to whether you had really taken it--but it was my first warning that you might be playing a deep game against me, incomprehensible as the action was to my mind. I subsequently reflected that I had been eating an apple, instead of taking the drink he first offered me, in the dead wretch's rooms on the night he came to his merited end. From this I a.s.sume that your design was in some way to compare what remained of the two apples--although I do not presume to fathom the depths of your detective system. Still, I have heard of many of your cases, and profoundly admire the keenness you exhibit. I am thought to be a keen man myself, but, although I was able, to some extent, to hold my own to-night, I admit that your ac.u.men in this case alone is something beyond me.

"I do not know by whom you are commissioned to hunt me, nor to what extent you may be acquainted with my connection with the creature I killed. I have sufficient respect for you, however, to wish that you should not regard me as a vicious criminal, and a couple of hours to spare in which to offer you an explanation that will convince you that such is not altogether the case. A hasty and violent temper I admit possessing; but even now I can not forget the one crime it has led me into--for it is, I suppose, strictly speaking, a crime. For it was the man Foggatt who made a felon of my father before the eyes of the world, and killed him with shame. It was he who murdered my mother, and none the less murdered her because she died of a broken heart. That he was also a thief and a hypocrite might have concerned me little but for that.

"Of my father I remember very little. He must, I fear, have been a weak and incapable man in many respects. He had no business abilities--in fact, was quite unable to understand the complicated business matters in which he largely dealt. Foggatt was a consummate master of all those arts of financial jugglery that make so many fortunes, and ruin so many others, in matters of company promoting, stocks, and shares. He was unable to exercise them, however, because of a great financial disaster in which he had been mixed up a few years before, and which made his name one to be avoided in future. In these circ.u.mstances he made a sort of secret and informal partnership with my father, who, ostensibly alone in the business, acted throughout on the directions of Foggatt, understanding as little what he did, poor, simple man, as a schoolboy would have done. The transactions carried on went from small to large, and, unhappily from honorable to dishonorable. My father relied on the superior abilities of Foggatt with an absolute trust, carrying out each day the directions given him privately the previous evening, buying, selling, printing prospectuses, signing whatever had to be signed, all with sole responsibility and as sole partner, while Foggatt, behind the scenes absorbed the larger share of the profits. In brief, my unhappy and foolish father was a mere tool in the hands of the cunning scoundrel who pulled all the wires of the business, himself unseen and irresponsible. At last three companies, for the promotion of which my father was responsible, came to grief in a heap. Fraud was written large over all their history, and, while Foggatt retired with his plunder, my father was left to meet ruin, disgrace, and imprisonment. From beginning to end he, and he only, was responsible. There was no shred of evidence to connect Foggatt with the matter, and no means of escape from the net drawn about my father. He lived through three years of imprisonment, and then, entirely abandoned by the man who had made use of his simplicity, he died--of nothing but shame and a broken heart.

"Of this I knew nothing at the time. Again and again, as a small boy, I remember asking of my mother why I had no father at home, as other boys had--unconscious of the stab I thus inflicted on her gentle heart. Of her my earliest, as well as my latest, memory is that of a pale, weeping woman, who grudged to let me out of her sight.

"Little by little I learned the whole cause of my mother's grief, for she had no other confidant, and I fear my character developed early, for my first coherent remembrance of the matter is that of a childish design to take a table-knife and kill the bad man who had made my father die in prison and caused my mother to cry.

"One thing, however, I never knew--the name of that bad man. Again and again, as I grew older, I demanded to know, but my mother always withheld it from me, with a gentle reminder that vengeance was for a greater hand than mine.

"I was seventeen years of age when my mother died. I believe that nothing but her strong attachment to myself and her desire to see me safely started in life kept her alive so long. Then I found that through all those years of narrowed means she had contrived to sc.r.a.pe and save a little money--sufficient, as it afterward proved, to see me through the examinations for entrance to my profession, with the generous a.s.sistance of my father's old legal advisers, who gave me my articles, and who have all along treated me with extreme kindness.

"For most of the succeeding years my life does not concern the matter in hand. I was a lawyer's clerk in my benefactors' service, and afterward a qualified man among their a.s.sistants. All through the firm were careful, in pursuance of my poor mother's wishes, that I should not learn the name or whereabouts of the man who had wrecked her life and my father's. I first met the man himself at the Clifton Club, where I had gone with an acquaintance who was a member. It was not till afterward that I understood his curious awkwardness on that occasion. A week later I called (as I had frequently done) at the building in which your office is situated, on business with a solicitor who has an office on the floor above your own.

On the stairs I almost ran against Mr. Foggatt. He started and turned pale, exhibiting signs of alarm that I could not understand, and asked me if I wished to see him.
