few years back. It had been a most disastrous affair for a local express, and Catesby had been acting as guard to the train. He spoke of it under his breath.
"I dream of it occasionally even now," he said. "The engine left the line and dragged the train over the embankment into the river. If you ask me how I managed to escape, I can't tell you. I never come into Lydmouth with the night express now without my head out of the window of the van right away from the viaduct till she pulls up at the station. And what's more, I never shall. It isn't fear, mind you, because I've as much pluck as any man. It's just nerves."
"We get 'em in our profession, too," Merrick smiled. "Did you happen to be looking out of the window on the night of the murder?"
"Yes, and every other night, too. Haven't I just told you so? Directly we strike the viaduct I come to my feet by instinct."
"Always look out the same side, I suppose?"
"Yes, on the left. That's the platform side, you understand."
"Then if anybody had left the train there——"
"Anybody left the train! Why we were traveling at fifty miles an hour when we reached the viaduct. Oh, yes, if anybody had left the train I should have been bound to see them, of course."
"But you can't see out of both windows at once."
"Nobody could leave the train by the other side. The stone parapet of the viaduct almost touches the footboard, and there's a drop of ninety feet below that. Of course I see what you are driving at, Mr. Merrick. Now look here. I locked Mr. Skidmore in the carriage myself, and I can prove that nobody got in before we left London. That would have been too dangerous a game so long as the train was passing any number of brilliantly lighted stations, and by the time we got into the open we were going at sixty miles an hour. That speed never slackened till we were just outside Lydmouth, and I was watching at the moment that our pace dropped. I had my head out of the window of my van till we pulled up by the platform. I am prepared to swear to all this if you like. Lord knows how the thing was done, and I don't suppose anybody else ever will."
"You are mistaken there," said Merrick drily. "Now, what puzzles you, of course, is the manner in which the murderer left the train."
"Well, isn't that the whole mystery?"
"Not to me. That's the part I really do know. Not that I can take any great credit to myself, because luck helped me. It was, perhaps, the most amazing piece of luck I have ever had. It was my duty, of course, to take no chances, and I didn't. But we'll come to that presently. Let it suffice for the moment that I know how the murderer left the train. What puzzles me is to know how he got on it. We can dismiss every other passenger in the train, and we need not look for an accomplice. There were accomplices, of course, but they were not on the express. Why didn't Mr. Skidmore travel in one of the corridor coaches?"
"He was too nervous. He always had a first-class carriage to himself. We knew he was coming, and that was why we attached an ordinary first-class coach to the train. We shouldn't do it for anybody, but Lord Rendelmore, the chairman of Mr. Skidmore's bank, is also one of our directors. The coach came in handy the other night because we had an order from a London undertaker to bring a corpse as far as here—to Lydmouth."
"Really! You would have to have a separate carriage for that."
"Naturally, Mr. Merrick. It was sort of killing two birds with one stone."
"I see. When did you hear about the undertaking job?"
"The same morning we heard from the bank that Mr. Skidmore was going to Lydmouth. We reserved a coach at once, and had it attached to the Express. The other carriages were filled with ordinary passengers."
"Why didn't I hear of this before?" Merrick asked.
"I don't know. It doesn't seem to me to be of much importance. You might just as well ask me questions as to the passengers' baggage."
"Everything is of importance," Merrick said sententiously. "In our profession, there are no such things as trifles. I suppose there will be no difficulty in getting at the facts of this corpse business. I'll make inquiries here presently."
So far Merrick professed himself to be satisfied. But there were still difficulties in the way. The station people had a clear recollection of the receipt of a coffin on the night of the tragedy, and, late as it was, the gruesome thing had been fetched away by the people whom it was consigned to. A plain hearse, drawn by one horse, had been driven into the station yard, the consignment note had been receipted in the usual way, and there was an end of the matter. Lydmouth was a big place, with nearly a quarter of a million of inhabitants, and would necessarily contain a good many people in the undertaking line. Clearly it was no business of the railway company to take this thing any further.
Merrick admitted that freely enough. It was nearly dark when he came back to the station, profoundly dissatisfied with a wasted afternoon.
"No good," he told Catesby. "At the same time there are consolations. And, after all, I am merely confirming my suspicions. I suppose your people here are on the telephone. If so, I should like to send a message to your head office. I want the name of the firm in London who consigned the coffin here. I suppose the stationmaster could manage this for me."
An hour or so later the information came. Merrick, at the telephone, wanted a little further assistance. Would the Grand Coast Railway call up the undertaker's firm whilst he held the line and ask the full particulars as to the body sent from London to Lydmouth. For half an hour Merrick stood patiently there till the reply came.
"Are you there? Is that Inspector Merrick? Oh, yes. Well, we have called up Lincoln & Co., the undertakers. We got on to the manager himself. He declares that the whole thing is a mistake. They have not sent a corpse over our trunk system for two months. I read the manager the letter asking for special facilities, a letter on the firm's own paper. The manager does not hesitate to say the whole thing is a forgery. I think he is right, Inspector. If we can do anything else for you——"
Merrick hung up the receiver and smiled as if pleased with himself. He turned to his companion, Catesby.
"It's all right," he said. "Is there any way we can get back to London to-night? The whole thing is perfectly plain, now."
Though Merrick returned to London thoroughly satisfied, he knew that the sequel was not just yet. There was much conjuring work to be done before it would be possible to place all the cards on the table. The Christmas holidays had arrived before Merrick obtained a couple of warrants, and, armed with these, he went down to Brighton on Boxing Day, and put up at the Hotel Regina, registering himself as Colonel Beaumont, sometime of the United States Field Forces. Merrick could pose as an authority on Cuba, for on one occasion he had been there for six months on the lookout for a defaulting bank manager. He had made certain changes in his appearance, and just now he bore little resemblance to Inspector Merrick of New Scotland Yard.
The big hotel on the front was full. There was a smart dance that same night, preceded by a children's party and Christmas tree. The house swarmed with young folks, and a good many nationalities were represented. On occasions like these somebody generally takes the lead, and by common consent the part of the chief of the events had been allotted to the Marquis de Branza.
To begin with, he was immensely rich. He had vast estates in Italy. He had been staying at the Regina for the past month, and it was whispered that his bill had reached three figures. He entertained lavishly; he was the soul of hospitality; he was
