"It seems that when the midday train, London to Folkestone, stopped at Swanley Junction, two passengers who were about to enter a first-class compartment in one of the corridor carriages were horrified to find it in a terrible state of disorder. They hastily called the guard, and on examination the carriage looked indeed as if it had been the scene of a violent struggle: the door on the off side was unlatched, two of the window straps were wrenched off, the anti-macassars were torn off the cushions, one of the luggage racks was broken, and the net hung down in strips, and over some of the cushions were marks unmistakably made by a blood-stained hand.
"The guard immediately locked the compartment and sent for the local police. No one was allowed in or out of the station until every passenger on the train had satisfied the police as to his or her identity. Thus the train was held up for over two hours whilst preliminary investigations were going on.
"There appeared no doubt that a terrible murder had been committed, and telephonic communication all along the line presently established the fact that it must have been done somewhere in the neighbourhood of Sydenham Hill, because a group of men who were at work on the 'up' side of the line at Penge, when the down train came out of the tunnel noticed that the door of one of the first-class carriages was open. It swung to again just before the train steamed through the station.
"A preliminary search was at once made in and about the tunnel; it revealed on the platform of Sydenham Hill station a first-class single ticket of that day's issue, London to Folkestone, crushed and stained with blood, and on the permanent way, close to the entrance of the tunnel on the Penge side, a soft black hat, and a broken pair of pince-nez. But as to the identity of the victim there was for the moment no clue.
"After a couple of wearisome and anxious hours the passengers were allowed to proceed on their journey. Among these passengers, it appears, were John and Henry Carter, who were on their way to the Smithson wedding. Until they arrived in Folkestone they had no more idea than the police who the victim of the mysterious train murder was: but in the station they caught side of Mr. Sutherland Ford, whom they knew slightly. Mr. Ford was making agitated enquiries as to any possible accident on the line. The Carters put him au fait of what had occurred, and as there was no sign of the Russian Prince amongst the passengers who had just arrived, all three men came to the horrifying conclusion that it was indeed the bridegroom elect who had been murdered.
"They communicated at once with the police, and there were more investigations and telephonic messages up and down the line before the Carters and Mr. Ford were at last allowed to proceed to the church and break the awful news to those most directly concerned.
"And in this tragic fashion did Louisa Smithson's wedding-day draw to its end; nor, as far as the public was concerned, was the mystery of that terrible murder ever satisfactorily cleared up. The local police worked very hard and very systematically, but, though presently they also had the help of one of the ablest detectives from Scotland Yard, nothing was seen or found that gave the slightest clue either as to the means which the murderer or murderers adopted for removing the body of their victim, or in what manner they made good their escape. The body of the Russian Prince was never found, and, as far as the public knows, the murderer is still at large; and although, as time went on, many strange facts came to light, they only helped to plunge that extraordinary crime into darker mystery."

"The facts in themselves were curious enough, you will admit," the Old Man in the Corner went on after a while. "Many of these were never known to the public, whilst others found their way into the columns of the halfpenny Press, who battened on the 'Mystery of the Russian Prince' for weeks on end, and, as far as the unfortunate Smithsons were concerned, there was not a reader of the Express Post and kindred newspapers who did not know the whole of their family history.
"It seems that Louisa Smithson is the daughter of a grocer in Folkestone, who had retired from business just before the War, and with his wife and his only child led a meagre and obscure existence in a tiny house in Warren Avenue somewhere near the tram road. They were always supposed to be very poor, but suddenly old Smithson died and it turned out that he had been a miser, for he left the handsome little fortune of fifteen thousand pounds to be equally divided between his daughter and his widow.
