But though French felt sure enough of his ground so far, on trying to take a further step he was held up by the same difficulty with which he had been faced in considering the forged letters. Was Gething guilty, and had he invented this elaborate plan to throw suspicion on to Vanderkemp, or was Vanderkemp the criminal, and the story his scheme for accounting for his actions since the murder? That was a real difficulty, and French sat wondering if there was no test he could apply, no way in which he could reach certainty, no trap which the victim would be unable to avoid?
For some time he could think of none, but presently an idea occurred to him which he thought might be worth while following up. Some information might be gained through the typewriting of the two forged letters. Could Vanderkemp type, and if so, was his work done with a light or heavy touch? He turned to his companion.
“I wish you would write me a short statement of your movements in London on the night of the crime, stating the times at which you arrived at and left the various places you visited. I should prefer it typed—that is, if you can type. Can you?”
Vanderkemp smiled wanly.
“I think so,” he answered. “I type and write shorthand in four languages. But I’ve no machine here.”
“Borrow one from the office,” French suggested, as he expressed his admiration of the other’s prowess.
It took a personal visit to the office, but Vanderkemp, anxious to defer to the Inspector’s whims, managed to overcome the scruples of the languorous, dark-eyed beauty who reigned therein, and returned triumphant with the machine. Ten minutes later French had his timetable.
Instantly he saw that Vanderkemp typed as an expert—with a light, sure touch that produced a perfect impression, but did not dint the paper. It was a point in the man’s favour. By no means conclusive, it was still by no means negligible.
Inspector French was puzzled. His experience told him that in this world the ordinary, natural and obvious thing happened. A man who secretly visited the scene of a crime at about the hour at which the crime was known to be committed, and who then left the country on a mysterious and improbable mission, the reality of which was denied by its alleged author, a man, further, who had in his pocket banknotes stolen from the scene of the crime, such a man in ordinary, prosaic, everyday life was the criminal. Such, French thought, was common sense, and common sense, he considered, was right ninety-nine times out of a hundred.
But there was always the hundredth chance. Improbabilities and coincidences did occasionally happen. He would have given a good deal at that moment to know if this case was the exception that proves the rule.
He saw clearly that his second explanation, if somewhat more farfetched, was still quite possibly true. It certainly might be that Vanderkemp had been duped, that he had been sent on this wild goose chase by the murderer, with the object of drawing on himself just that suspicion which he had attracted, and thus allowing the real scent to cool. A good many of the facts tended in that direction, the forged letters, the keeping of the alleged deal from Schoofs, the fact that no Russian nobleman had turned up at either of the rendezvous named, the travelling under a false name, the warning against communications with the office, and last, but not least, Vanderkemp’s manner during the interview, all these undoubtedly supported the view that the traveller had been used to lay a gigantic false clue.
If so, it was a fiendish trap to set for the unfortunate dupe. French thought he could see how it was intended to pan out. Vanderkemp, while on these mysterious journeys—certainly when he reached Mr. Duke’s agent in Constantinople—would learn of the murder, and he would at once see how he had been victimised. The more he learned of the details, the more he would realise how completely he was in the toils. He would recognise that if he went home and told his story he would not have a dog’s chance of clearing himself, and he would turn his apparent flight into a real one, and so permanently fasten upon himself a tacit admission of guilt. It was an ingenious scheme, and if it really were the explanation of these mysterious happenings, it gave an indication of the character and mentality of the man who had devised it.
French was by no means decided as to the truth of the matter, but on the whole he thought that though he undoubtedly had evidence to justify him in applying for the arrest and extradition of the traveller, he would prefer to avoid this step if possible. If the man tried to give him the slip, the local police would get him in no time. Accordingly he turned once more to Vanderkemp.
“Mr. Vanderkemp,” he began, “I am strongly inclined to believe your story. But as a man of the world you will readily see that it must be more completely examined before it can be fully accepted. Now the question is, Are you willing to come back with me to London and give me your assistance towards finding out the truth? I can make you no promise that you will not be arrested on reaching British ground, but I can promise you that you will be fairly dealt with and get every chance and assistance to prove your innocence.”
Vanderkemp did not hesitate in his reply.
“I will go,” he said promptly. “I am aware that you can have me arrested here, if you want to, by applying to the Spanish authorities, so I have no choice. But I think I
