"Lummy, sir, so I did. Then where could he a-went to--and how?"

"Station-master," struck in Cleek, turning from examining the body, "get your men to examine all tickets, both in the train and out of it, and if there's one that's not clipped as it pa.s.sed the barrier at London Bridge, look out for it, and detain the holder. I'll take the gate here, and examine all local tickets. Meantime, wire all up the road to every station from here to London Bridge, and find out if any other signalman than the one at Forest Hill noticed this dark compartment when the train went past."

Both suggestions were acted upon immediately. But every ticket, save, of course, the season ones--and the holders of these were in every case identified--was found to be properly clipped; and, in the end, every signal-box from New Cross on wired back: "All compartments lighted when train pa.s.sed here."

"That narrows the search, Mr. Narkom," said Cleek, when he heard this.

"The lights were put out somewhere between Honor Oak Park and Forest Hill, and it was between Honor Oak Park and Anerley the murderer made his escape. Inspector"--he turned to the officer in command of the local police--"do me a favour. Put your men in charge of this carriage, and let the train proceed. Norwood Junction is the next station, I believe, and there's a side track there. Have the carriage shunted, and keep close guard over it until Mr. Narkom and I arrive."

"Right you are, sir. Anything else?"

"Yes. Have the station-master at the junction equip a hand-car with a searchlight, and send it here as expeditiously as possible. If anybody or anything has left this train between this point and Honor Oak Park, Mr. Narkom, this thin coating of snow will betray the fact beyond the question of a doubt."

Twenty minutes later the hand-car put in an appearance, manned by a couple of linemen from the junction, and, word having been wired up the line to hold back all trains for a period of half an hour in the interests of Scotland Yard, Cleek and Narkom boarded the vehicle, and went whizzing up the metals in the direction of Honor Oak Park, the shifting searchlight sweeping the path from left to right and glaring brilliantly on the surface of the fallen snow.

Four lines of tracks gleamed steel-bright against its spotless level--the two outer ones being those employed by the local trains going to and fro between London and the suburbs, the two inner ones belonging to the main line--but not one footstep indented the thin surface of that broad expanse of snow from one end of the journey to the other.

"The murderer, whoever he is or wherever he went, never set foot upon so much as one inch of this ground, that's certain," said Narkom, as he gave the order to reverse the car and return. "You feel satisfied of that, do you not, my dear fellow?"

"Thoroughly, Mr. Narkom; there can't be two opinions upon that point.

But, at the same time, he _did_ leave the train, otherwise we should have found him in it."

"Granted. But the question is, _when_ did he get in and _how_ did he get out? We know from the evidence of the pa.s.sengers that the train never stopped for one instant between London Bridge station and Anerley; that all compartments were alight up to the time it pa.s.sed Honor Oak Park; that n.o.body abroad of it heard a sound of a pistol-shot; that the a.s.sa.s.sin could not have crept along the footboard and got into some other compartment, for _all_ were so densely crowded that half a dozen people were standing in each, so he could not have entered without somebody making room for him to open the door and get in. No such thing happened, no such thing could happen, without a dozen or more people being aware of it; so the idea of a confederate may be dismissed without a thought. The unmarked surface of the snow shows that n.o.body alighted, was thrown out, or fell out between the two points where the tragedy must have occurred; both windows were shut and both doors of the compartment locked when the train made its first stop; yet the fellow was gone. My dear chap, are you sure, are you really _sure_, that it isn't a case of suicide after all?"

Cleek gave his shoulders a lurch and smiled indulgently.

"My dear Mr. Narkom," he said, "the position of the revolver in the dead man's hand ought, as I pointed out to you, to settle that question, even if there were no other discrepancies. In the natural order of things, a man who had just put a bullet into his own brain would, if he were sitting erect, as Lord Stavornell was, drop the revolver in the spasmodic opening and shutting of the hands in the final convulsion; but, if he retained any sort of a hold upon it, be sure his forefinger would be in the loop of the trigger. He wouldn't be holding the weapon backward, so to speak, with the cylinder against the ball of his thumb and the hammer against the base of the middle finger. If he had held it that way he simply couldn't have shot himself if he had tried. Then, if you didn't remark it, there was no scorch of powder upon the face, for another thing; and, for a third, the bullet-hole was between the eyes, a most unlikely target for a man bent upon blowing out his own brains; the temple or the roof of the mouth are the points to which natural impulse----" He stopped and laid a sharp, quick-shutting hand on the shoulder of one of the two men who were operating the car. "Turn back!"

he exclaimed. "Reverse the action, and go back a dozen yards or so."

The impetus of the car would not permit of this at once, but after running on for a little time longer it answered to the brake, slowed down, stopped, and then began to back, scudding along the rail until Cleek again called it to a halt. They were within gunshot of the station at Sydenham when this occurred; the glaring searchlight was still playing on the metals and the thin layer of snow between, and Cleek's face seemed all eyes as he bent over and studied the ground over which they were gliding. Of a sudden, however, he gave a little satisfied grunt, jumped down, and picked up a shining metal object, about two and a half inches long, which lay in the s.p.a.ce between the tracks of the main and the local lines. It was a guard's key for the locking and unlocking of compartment doors, one of the small T-shaped kind that you can buy of almost any iron-monger for sixpence or a shilling any day. It was wet from contact with the snow, but quite unrusted, showing that it had not been lying there long, and it needed but a glance to reveal the fact that it was brand new and of recent purchase.

Cleek held it out on his palm as he climbed back upon the car and rejoined Narkom.

"Wherever he got on, Mr. Narkom, here is where the murderer got off, you see, and either dropped or flung away this key when he had relocked the compartment after him," he said. "And yet, as you see, there is not a footstep, beyond those I have myself just made, to be discovered anywhere. From the position in which this key was lying, one thing is certain, however: our man got out on the opposite side from the platform toward which the train was hastening and in the middle of the right of way."

"What a mad idea! If there had been a main line express pa.s.sing at the time the fellow ran the risk of being cut to pieces. None of them slow down before they prepare to make their first stop at East Croydon, and about this spot they would be going like the wind."

"Yes," said Cleek, looking fixedly at the shining bit of metal on his palm; "going like the wind. And the suction would be enormous between two speeding trains. A step outside, and he'd have been under the wheels in a wink. Yes, it would have been certain death, instant death, if there had been a main line train pa.s.sing at the time; and that he was not sucked down and ground under the wheels proves that there _wasn't_."

Then he puckered up his brows in that manner which Narkom had come to understand meant a thoughtfulness it was impolitic to disturb, and stood silent for a long, long time.

"Mr. Narkom," he said suddenly, "I think we have discovered all that there is to be discovered in this direction. Let us get on to Norwood Junction as speedily as possible. I want to examine that compartment and that dead body a little more closely. Besides, our half hour is about up, and the trains will be running again shortly, so we'd better get out of the way."

"Any ideas, old chap?"

"Yes, bushels of them. But they all may be exploded in another half hour. Still, these are the days of scientific marvels. Water does run uphill and men do fly, and both are in defiance of the laws of gravitation."

"Which means?"

"That I shall leave the hand-car at Sydenham, Mr. Narkom, and 'phone up to London Bridge station; there are one or two points I wish to ask some questions about. Afterward I'll hire a motor from some local garage and join you at Norwood Junction in an hour's time. Let no one see the body or enter the compartment where it lies until I come. One question, however: is my memory at fault, or was it not Lord Stavornell who was mixed up in that little affair with the French dancer, Mademoiselle Fifi de Lesparre, who was such a rage in town about a year ago?"

"Yes; that's the chap," said Narkom in reply. "And a rare bad lot he has been all his life, I can tell you. I dare say that Fifi herself was no better than she ought to have been, chucking over her country-bred husband as soon as she came into popularity, and having men of the Stavornell cla.s.s tagging after her; but whether she was or was not, Stavornell broke up that home. And if that French husband had done the right thing, he would have thrashed him within an inch of his life instead of acting like a fool in a play and challenging him. Stavornell laughed at the challenge, of course; and if all that is said of him is true, he was at the bottom of the shabby trick which finally forced the poor devil to get out of the country. When his wife, Fifi, left him, the poor wretch nearly went off his head; and, as he hadn't fifty shillings in the world, he was in a d.i.c.kens of a pickle when _somebody_ induced a lot of milliners, dressmakers, and the like, to whom it was said that Fifi owed bills, to put their accounts into the hands of a collecting agency and to proceed against him for settlement of his wife's accounts.

That was why he got out of the country post-haste. The case made a great stir at the time, and the scandal of it was so great that, although the fact never got into the papers, Stavornell's wife left him, refusing to live another hour with such a man."

"Oh, he had a wife, then?"

"Yes; one of the most beautiful women in the kingdom. They had been married only a year when the scandal of the Fifi affair arose. That was another of his dirty tricks forcing that poor creature to marry him."

"She did so against her will?"

"Yes. She was engaged to another fellow at the time, an army chap who was out in India. Her father, too, was an army man, a Colonel Something-or-other, poor as the proverbial church mouse, addicted to hard drinking, card-playing, horse-racing, and about as selfish an old brute as they make 'em. The girl took a deep dislike to Lord Stavornell the minute she saw him; knew his reputation, and refused to receive him.

That's the very reason he determined to marry her, humble her pride, as it were, and repay her for her scorn of him.

"He got her father into his clutches, deliberately, of course, lent him money, took his I O U's for card debts and all that sort of thing, until the old brute was up to his ears in debt and with no prospect of paying it off. Of course, when he'd got him to that point, Stavornell demanded the money, but finally agreed to wipe the debt out entirely if the daughter married him. They went at her, poor creature, those two, with all the mercilessness of a couple of wolves. Her father would be disgraced, kicked out of the army, barred from all the clubs, reduced to beggary, and all that, if she did not yield; and in the end they so played upon her feelings, that to save him she gave in; Stavornell took out a special license, and they were married. Of course, the man never cared for her; he only wanted his revenge on her, and they say he led her a dog's life from the hour they came back to England from their honeymoon."

"Poor creature!" said Cleek sympathetically. "And what became of the other chap, the lover she wanted to marry and who was out in India at the time all this happened?"

"Oh, they say he went on like a madman when he heard it. Swore he'd kill Stavornell, and all that, but quieted down after a time, and accepted the inevitable with the best grace possible. Crawford is his name. He was a lieutenant at the time, but he's got his captaincy since, and I believe is on leave and in England at present--as madly and as hopelessly in love with the girl of his heart as ever."

"Why 'hopelessly,' Mr. Narkom? Such a man as Stavornell must have given his wife grounds for divorce a dozen times over."

"Not a doubt of it. There isn't a judge in England who wouldn't have set her free from the scoundrel long ago if she had cared to bring the case into the courts. But Lady Stavornell is a strong Church-woman, my dear fellow; she doesn't believe in divorce, and nothing on earth could persuade her to marry Captain Crawford so long as her first husband still remained alive."

"Oho!" said Cleek. "Then Fifi's husband isn't the only man with a grievance and a cause? There's another, eh?"

"Another? I expect there must be a dozen, if the truth were known.

There's only one creature in the world I ever heard of as having a good word to say for the man."

"And who might that be?"

"The Hon. Mrs. Brinkworth, widow of his younger brother. You'd think the man was an angel to hear her sing his praises. Her husband, too, was a wild sort. Left her up to her ears in debt, without a penny to bless herself, and with a boy of five to rear and educate. Stavornell seems always to have liked her. At any rate, he came to the rescue, paid off the debts, settled an annuity upon her, and arranged to have the boy sent to Eton as soon as he was old enough. I expect the boy is at the bottom of this good streak in him if all is told; for, having no children of his own---- I say! By George, old chap! Why, that nipper, being the heir in the direct line, is Lord Stavornell now that the uncle is dead! A lucky stroke for him, by Jupiter!"

"Yes," agreed Cleek. "Lucky for him; lucky for Lady Stavornell; lucky for Captain Crawford; and _unlucky_ for the Hon. Mrs. Brinkworth and Mademoiselle Fifi de Lesparre. So, of course---- Sydenham at last.

Good-bye for a little time, Mr. Narkom. Join you at Norwood Junction as soon as possible, and---- I say!"

"Yes, old chap?"

"Wire through to the Low Level station at Crystal Palace, will you? and inquire if anybody has mislaid an ironing-board or lost an Indian canoe.

See you later. So long."

Then he stepped up on to the station platform, and went in quest of a telephone booth.

II

It was after nine o'clock when he turned up at Norwood Junction, as calm, serene, and imperturbable as ever, and found Narkom awaiting him in a small private room which the station clerk had placed at his disposal.

"My dear fellow, I never was so glad!" exclaimed the superintendent, jumping up excitedly as Cleek entered. "What kept you so long? I've been on thorns. Got bushels to tell you. First off, as Stavornell's ident.i.ty is established beyond doubt, and no time has been lost in wiring the news of the murder to his relatives, both Lady Stavornell and Mrs.

Brinkworth have wired back that they are coming on. I expect them at any minute now. And here's a piece of news for you. Fifi's husband is in England. The Hon. Mrs. Brinkworth has wired me to that effect. Says she has means of knowing that he came over from France the other day; and that she herself saw him in London this morning when she was up there shopping."
