cap.
"Saloon carriage being coupled up behind, my lord," he said.
The problem was solved. The guard glanced at his watch. It seemed to him that both the bank messenger and the undertaker were cutting it fine. The coffin came presently on a hand-truck—a black velvet pall lay over it, and on the sombre cloth a wreath or two of white lilies. The door of the carriage was closed presently, and the blinds drawn discreetly close. Following behind this came a barrow in charge of a couple of platform police. On the barrow were two square deal boxes, heavy out of all proportion to their size. These were deposited presently to the satisfaction of a little nervous-looking man in gold-rimmed glasses. Mr. George Skidmore, of the Imperial Bank, had his share of ordinary courage, but he had an imagination, too, and he particularly disliked these periodical trips to branch banks, in convoy, so to speak. He took no risks.
"Awful night, sir," the guard observed. "Rather lucky to get a carriage to yourself, sir. Don't suppose you would have done so only we're taking a corpse as far as Lydmouth, which is our first stop."
"Really?" Skidmore said carelessly. "Ill wind that blows nobody good, Catesby. I may be overcautious, but I much prefer a carriage to myself. And my people prefer it, too. That's why we always give the railway authorities a few days' notice. One can't be too careful, Catesby."
The guard supposed not. He was slightly, yet discreetly, amused to see Mr. Skidmore glance under the seats of the first-class carriage. Certainly there was nobody either there or on the racks. The carriage at the far side was locked, and so, now, was the door next the platform. The great glass dome was brilliantly lighted so that anything suspicious would have been detected instantly. The guard's whistle rang out shrill and clear, and Catesby had a glimpse of Mr. Skidmore making himself comfortable as he swung himself into his van. The great green and gold serpent with the brilliant electric eyes fought its way sinuously into the throat of the wet and riotous night on its first stage of over two hundred miles. Lydmouth would be the first stop.
So far Mr. Skidmore had nothing to worry him, nothing, that is, except the outside chance of a bad accident. He did not anticipate, however, that some miscreant might deliberately wreck the train on the off chance of looting those plain deal boxes. The class of thief that banks have to fear is not guilty of such clumsiness. Unquestionably nothing could happen on this side of Lydmouth. The train was roaring along now through the fierce gale at sixty odd miles an hour, Skidmore had the carriage to himself, and was not the snug, brilliantly lighted compartment made of steel? On one side was the carriage with the coffin; on the other side another compartment filled with a party of sportsmen going North. Skidmore had noticed the four of them playing bridge just before he slipped into his own carriage. Really, he had nothing to fear. He lay back comfortably wondering how Poe or Gaboriau would have handled such a situation with a successful robbery behind it. There are limits, of course, both to a novelist's imagination and a clever thief's process of invention. So, therefore. …
Three hours and twenty minutes later the express pulled up at Lydmouth. The station clock indicated the hour to be 11.23. Catesby swung himself out of his van on to the shining wet platform. Only one passenger was waiting there, but nobody alighted. Catesby was sure of this, because he was on the flags before a door could be opened. He came forward to give a hand with the coffin in the compartment next to Skidmore's. Then he noticed, to his surprise, that the glass in the carriage window was smashed; he could see that the little cashier was huddled up strangely in one corner. And Catesby could see also that the two boxes of bullion were gone!
Catesby's heart was thumping against his ribs as he fumbled with his key. He laid his hand upon Skidmore's shoulder, but the latter did not move. The fair hair hung in a mass on the side of his forehead, and here it was fair no longer. There was a hole with something horribly red and slimy oozing from it. The carpet on the floor was piled up in a heap; there were red smears on the cushions. It was quite evident that a struggle had taken place here. The shattered glass in the window testified to that. And the boxes were gone, and Skidmore had been murdered by some assailant who had shot him through the brain. And this mysterious antagonist had got off with the bullion, too.
A thing incredible, amazing, impossible; but there it was. By some extraordinary method or another the audacious criminal had boarded an express train traveling at sixty miles an hour in the teeth of a gale. He had contrived to enter the cashier's carriage and remove specie to the amount of eight thousand pounds! It was impossible that only one man could have carried it. But all the same it was gone.
Catesby pulled himself together. He was perfectly certain that nobody at present on the train had been guilty of this thing. He was perfectly certain that nobody had left the train. Nobody could have done so after entering the station without the guard's knowledge, and to have attempted such a thing on the far side of the river bridge would have been certain death to anybody. There was a long viaduct here—posts and pillars and chains, with tragedy lurking anywhere for the madman who attempted such a thing. And until the viaduct was reached the express had not slackened speed. Besides, the thief who had the courage and intelligence and daring to carry out a robbery like this was not the man to leave an express train traveling at a speed of upwards of sixty miles an hour.
The train had to proceed, there was no help for it. There was a hurried conference between Catesby and the stationmaster; after that the electric lamps in the dead man's carriage were unshipped, and the blinds pulled down. The matter would be fully investigated when Edinburgh was reached, meanwhile the stationmaster at Lydmouth would telephone the Scotch capital and let them know there what they had to expect. Catesby crept into his van again, very queer and dizzy, and with a sensation in his legs suggestive of creeping paralysis.
Naturally, the mystery of the night express caused a great sensation. Nothing like it had been known since the great crime on the South Coast, which is connected with the name of Lefroy. But that was not so much a mystery as a man hunt. There the criminal had been identified. But here there was no trace and no clue whatever. It was in vain that the Scotland Yard authorities tried to shake the evidence of the guard, Catesby. He refused to make any admissions that would permit the police even to build up a theory. He was absolutely certain that Mr. Skidmore had been alone in the carriage at the moment that the express left London; he was absolutely certain that he had locked the door of the compartment, and the engine driver could testify that the train had never traveled at a less speed than sixty miles an hour until the bridge over the river leading into Lydmouth station was reached; even then nobody could have dropped off the train without the risk of certain death. Inspector Merrick was bound to admit this himself when he went over the spot. And the problem of the missing bullion boxes was quite as puzzling in its way as the mysterious way in which Mr. Skidmore had met his death.
There was no clue to this either. Certainly there had been a struggle, or there would not have been blood marks all over the place, and the window would have remained intact. Skidmore had probably been forced back into his seat, or he had collapsed there after the fatal shot was fired. The unfortunate man had been shot through the brain with an ordinary revolver of common pattern, so that for the purpose of proof the bullet was useless. There were no finger marks on the carriage door, a proof that the murderer had either worn gloves or that he had carefully removed all traces with a cloth of some kind. It was obvious, too, that a criminal of this class would take no risks, especially as there was no chance of his being hurried, seeing that he had had three clear hours for his work. The more the police went into the matter, the more puzzled they were. It was not a difficult matter to establish the bona fides of the passengers who traveled in the next coach with Skidmore, and as to the rest it did not matter. Nobody could possibly have left any of the corridor coaches without attracting notice; indeed, the very suggestion was absurd. And there the matter rested for three days.
It must not be supposed that the authorities had been altogether idle. Inspector Merrick spent most of his time traveling up and down the line by slow local trains on the off-chance of hearing some significant incident that might lead to a clue. There was one thing obvious—the bullion boxes must have been thrown off the train at some spot arranged between the active thief and his confederates. For this was too big a thing to be entirely the work of one man. Some of the gang must have been waiting along the line in readiness to receive the boxes and carry them to a place of safety. By this time,
