A month elapsed, during which both the police and the company prosecuted their inquiries without the slightest success. A reward was offered and a pardon promised in case of crime, but they were both unclaimed. Every day the public opened their papers with the conviction that so grotesque a mystery would at last be solved, but week after week passed by, and a solution remained as far off as ever. In broad daylight, upon a June afternoon in the most thickly inhabited portion of England, a train with its occupants had disappeared as completely as if some master of subtle chemistry had volatilized it into gas. Indeed, among the various conjectures which were put forward in the public Press, there were some which seriously asserted that supernatural, or, at least, preternatural, agencies had been at work, and that the deformed Monsieur Caratal was probably a person who was better known under a less polite name. Others fixed upon his swarthy companion as being the author of the mischief, but what it was exactly which he had done could never be clearly formulated in words. Amongst the many suggestions put forward by various newspapers or private individuals, there were one or two which were feasible enough to attract the attention of the public. One which appeared in The Times, over the signature of an amateur reasoner of some celebrity at that date, attempted to deal with the matter in a critical and semi-scientific manner. An extract must suffice, although the curious can see the whole letter in the issue of the 3rd of July. "It is one of the elementary principles of practical reasoning," he remarked, "that when the impossible has been eliminated the residuum, HOWEVER IMPROBABLE, must contain the truth. It is certain that the train left Kenyon Junction. It is certain that it did not reach Barton Moss. It is in the highest degree unlikely, but still possible, that it may have taken one of the seven available side lines. It is obviously impossible for a train to run where there are no rails, and, therefore, we may reduce our improbables to the three open lines, namely the Carnstock Iron Works, the Big Ben, and the Perseverance. Is there a secret society of colliers, an English Camorra, which is capable of destroying both train and passengers? It is improbable, but it is not impossible. I confess that I am unable to suggest any other solution. I should certainly advise the company to direct all their energies towards the observation of those three lines, and of the workmen at the end of them. A careful supervision of the pawnbrokers' shops of the district might possibly bring some suggestive facts to light."
