front of my face in the matter.”
“Nor can I,” said the blind man, with a rather wry smile. “Never mind. The engine-driver is your client, of course?”
“Yes,” admitted Carlyle. “But how the deuce did you know?”
“Let us say that your sympathies are enlisted on his behalf. The jury were inclined to exonerate the signalman, weren’t they? What has the company done with your man?”
“Both are suspended. Hutchins, the driver, hears that he may probably be given charge of a lavatory at one of the stations. He is a decent, bluff, short-spoken old chap, with his heart in his work. Just now you’ll find him at his worst—bitter and suspicious. The thought of swabbing down a lavatory and taking pennies all day is poisoning him.”
“Naturally. Well, there we have honest Hutchins: taciturn, a little touchy perhaps, grown grey in the service of the company, and manifesting quite a bulldog-like devotion to his favourite 538.”
“Why, that actually was the number of his engine—how do you know it?” demanded Carlyle sharply.
“It was mentioned two or three times at the inquest, Louis,” replied Carrados mildly.
“And you remembered—with no reason to?”
“You can generally trust a blind man’s memory, especially if he has taken the trouble to develop it.”
“Then you will remember that Hutchins did not make a very good impression at the time. He was surly and irritable under the ordeal. I want you to see the case from all sides.”
“He called the signalman—Mead—a ‘lying young dog,’ across the room, I believe. Now, Mead, what is he like? You have seen him, of course?”
“Yes. He does not impress me favourably. He is glib, ingratiating, and distinctly ‘greasy.’ He has a ready answer for everything almost before the question is out of your mouth. He has thought of everything.”
“And now you are going to tell me something, Louis,” said Carrados encouragingly.
Mr Carlyle laughed a little to cover an involuntary movement of surprise.
“There is a suggestive line that was not touched at the inquiries,” he admitted. “Hutchins has been a saving man all his life, and he has received good wages. Among his class he is regarded as wealthy. I daresay that he has five hundred pounds in the bank. He is a widower with one daughter, a very nice-mannered girl of about twenty. Mead is a young man, and he and the girl are sweethearts—have been informally engaged for some time. But old Hutchins would not hear of it; he seems to have taken a dislike to the signalman from the first and latterly he had forbidden him to come to his house or his daughter to speak to him.”
“Excellent, Louis,” cried Carrados in great delight. “We shall clear your man in a blaze of red and green lights yet and hang the glib, ‘greasy’ signalman from his own signal-post.”
“It is a significant fact, seriously?”
“It is absolutely convincing.”
“It may have been a slip, a mental lapse on Mead’s part which he discovered the moment it was too late, and then, being too cowardly to admit his fault, and having so much at stake, he took care to make detection impossible. It may have been that, but my idea is rather that probably it was neither quite pure accident nor pure design. I can imagine Mead meanly pluming himself over the fact that the life of this man who stands in his way, and whom he must cordially dislike, lies in his power. I can imagine the idea becoming an obsession as he dwells on it. A dozen times with his hand on the lever he lets his mind explore the possibilities of a moment’s defection. Then one day he pulls the signal off in sheer bravado—and hastily puts it at danger again. He may have done it once or he may have done it oftener before he was caught in a fatal moment of irresolution. The chances are about even that the engine-driver would be killed. In any case he would be disgraced, for it is easier on the face of it to believe that a man might run past a danger signal in absentmindedness, without noticing it, than that a man should pull off a signal and replace it without being conscious of his actions.”
“The fireman was killed. Does your theory involve the certainty of the fireman being killed, Louis?”
“No,” said Carlyle. “The fireman is a difficulty, but looking at it from Mead’s point of view—whether he has been guilty of an error or a crime—it resolves itself into this: First, the fireman may be killed. Second, he may not notice the signal at all. Third, in any case he will loyally corroborate his driver and the good old jury will discount that.”
Carrados smoked thoughtfully, his open, sightless eyes merely appearing to be set in a tranquil gaze across the room.
“It would not be an improbable explanation,” he said presently. “Ninety-nine men out of a hundred would say: ‘People do not do these things.’ But you and I, who have in our different ways studied criminology, know that they sometimes do, or else there would be no curious crimes. What have you done on that line?”
To anyone who could see, Mr Carlyle’s expression conveyed an answer.
“You are behind the scenes, Max. What was there for me to do? Still I must do something for my money. Well, I have had a very close inquiry made confidentially among the men. There might be a whisper of one of them knowing more than had come out—a man restrained by friendship, or enmity, or even grade jealousy. Nothing came of that. Then there was the remote chance that some private person had noticed the signal without attaching any importance to it then, one who would be able to identify it still by something associated with the time. I went over the line myself. Opposite the signal the line on one side is shut in by a high blank wall; on the other side are houses, but coming below the butt-end of a scullery the signal does not happen to be visible from any road or from any window.”
“My poor Louis!” said Carrados, in friendly ridicule. “You were at the end of your tether?”
“I was,” admitted Carlyle. “And now that you know the sort of job it is I don’t suppose that you are keen on wasting your time over it.”
“That would hardly be fair, would it?” said Carrados reasonably. “No, Louis, I will take over your honest old driver and your greasy young signalman and your fatal signal that cannot be seen from anywhere.”
“But it is an important point for you to remember, Max, that although the signal cannot be seen from the box, if the mechanism had gone wrong, or anyone tampered with the arm, the automatic indicator would at once have told Mead that the green light was showing. Oh, I have gone very thoroughly into the technical points, I assure you.”
“I must do so too,” commented Mr Carrados gravely.
“For that matter, if there is anything you want to know, I dare say that I can tell you,” suggested his visitor. “It might save your time.”
“True,” acquiesced Carrados. “I should like to know whether anyone belonging to the houses that bound the line there came of age or got married on the twenty-sixth of November.”
Mr Carlyle looked across curiously at his host.
“I really do not know, Max,” he replied, in his crisp, precise way. “What on earth has that got to do with it, may I inquire?”
