The brakeman remained to close the switch and the stranger was bracing himself to couple the engine to the swift-moving cars when we should approach them.

No steam is ever used going down that hill; at the top of the incline the throttle-valve is closed and the speed of the train is controlled by the air-brake. But, as the stranger who had boarded the engine took his stand on the foot-board, I opened the throttle wide to give her a start, then put on the air until I had her under control, and then away we went. The runaway cars were fully one hundred yards ahead as we crossed the switch, and were moving apparently at the rate of eight or ten miles an hour with rapidly increasing momentum. In sixty seconds old 105 was running fifty miles an hour, and in thirty seconds more we were close to the cars. I heard the voice of the man in front shouting something, and knowing that it was to slow down in order to approach the cars without a crash, I applied the air. A slight jolt told me that the engine and car had come together, and after waiting an instant to give my unknown a.s.sistant time to drop the pin in place, I pulled the air-valve to lessen the speed. As the engine slowed under the pressure of the brake, I saw the cars glide away from us. He had missed the coupling. Again engine and cars came together and again I applied the air, with the same result.

We were running now at a speed of sixty or seventy miles an hour, and when you consider that the track on the hill is the crookedest ever surveyed by an engineer, cut up by deep ravines and canyons, and leading along high precipices, you can appreciate the danger of the run. Down the hill we thundered, swinging through deep cuts and around sharp curves, the engine swaying and swinging on her springs as if struggling in an effort to dash herself into one of the gorges lining the track. The engine was surrounded by rolling clouds of dust, through which at times I caught glimpses of the cars pitching and tossing like some dismantled vessel in a storm at sea. I knew the cars might jump the track at any moment and ditch the locomotive, sending the fireman and myself to quick death; but we must take the chances so long as there was a possibility of stopping the runaways.

Again and again we tried to make the coupling, but failed each time. I did not know, until all was over, the difficulties which the stranger was experiencing. The drawhead in the car was the old-fashioned single-link b.u.mper,--a man-killer we call it now,--and was so loose in its socket that it had to be raised six or eight inches and held in position while the link was being put in place. This required two hands, and as he could not maintain his position on the swaying foot-board without using one hand to cling to the handrail, he could not get the link in place and drop the pin through it.

By this time we were within three miles of Buckley. As the locomotive and fleeting cars dashed across a trestle one hundred feet high, I caught a glimpse of the little telegraph shanty down in the valley, surrounded by a network of rails. I opened the whistle and kept it shrieking until we were within two hundred yards of Buckley, but no one appeared on the station platform; and as we flashed past the telegraph office the white face of the operator, his eyes wide open with alarm and horror, appeared at the window for the fraction of an instant.

As we dashed past the telegraph office the long arm of the signal-board pointed down, and I thanked G.o.d that the next block was still open, and that we had another chance for life. We had eight miles of clear track and might yet prevent a disaster. The only hope, however, was in catching the runaway cars, as there was no telegraph office at Campton and No. 11 had left Mountain Springs and was booming towards us as fast as three big engines could send her, and without a stop ahead.

We crossed the half-mile of side-tracks at Buckley so fast that there was an unbroken rattle of clanking rails, and swung around the point of the mountain and down the winding track towards Campton. Over swaying bridges, through cuts, old 105 jolted us along at the rate of seventy or eighty miles an hour. In two minutes after crossing the yards at Buckley we were within sight of Campton, nestling below us in the valley. The man on the foot-board had been silent seemingly for hours, and whether he was still at his post or had fallen on the rails and been ground to pieces, I did not know. I realised now that there was no longer a possibility of stopping the cars by coupling to them, and what my hope was, if I had any at all, I do not know; there was only a mad determination to follow those runaway cars to the end and die with the rest.

As the roofs of Campton came into view the whistle began to sound again. Three miles below lay the half-deserted mining camp; now I could see the rough board station, the red and white switch targets, and the dark spots on the mountain-side that marked the abandoned test-shafts. Then I distinguished a form on the station platform, a slender form in dark calico and wearing a sun-bonnet. The woman's back was towards me, but I knew her to be Nettie Bascom, the daughter of the one-legged flagman. It was ten seconds, perhaps, before the girl heard the whistle; then she turned slowly, looking an instant towards us, and, with a quick spring, was at a switch-stand and had thrown the lever, and the white of the target turned to red and we were safe. But not so the pa.s.senger train. The cars had pa.s.sed over the switch before it could be turned, and in another moment the sound of its bounding wheels, our own cries, and all the other noises of the dreadful moment, were drowned by an explosion that lifted old 105 off the rails and laid everyone within sight insensible on the road. Those cars which we had chased unavailingly for thirty miles or more were laden with dynamite, and when they crashed into that train----

Do you ask about the man who shared my peril, and all to so little purpose? I can tell you nothing about him. Whether my former conclusion was correct and he had been shaken from his narrow hold into some ditch or gully, or whether he was hurled to destruction at the time of the explosion, I cannot say. I only know that I never saw him again alive or dead.

Below was added a line by the editor:

This is an offhand relation of the catastrophe in which Mrs.

Leighton Gillespie lost her life. She will be remembered by New York aristocracy as the brilliant, if eccentric, daughter-in-law of Archibald Gillespie, the multi-millionaire.

I returned the slip to Dr. Bennett. The excitement of that wild ride was upon me, and I seemed to have been present at the catastrophe it was intended to avert.

"Mountain Springs is in the West, I judge. How came the Gillespies there, and why was she the sole sufferer? Was he not on the train with her?"

"That is one of the peculiar features of the affair. He was not on the train, but he turned up at the wreck. Those who saw him there say that he worked like a giant, nay, like a t.i.tan, amongst those ghastly ruins. Finally he found her. She was quite dead. After that he worked no more. It is a story of unmitigated horror, and the agonies of that awful finding might well leave an indelible impression on his brain."

"I am glad you recognise this possibility. The effect of such a scene, even where no personal interests are involved, often leaves a man's nerves in a shaken condition for years. Besides--forgive me if I press my theory beyond all reason--another possibility has been suggested to me by this engineer's tale. I will not broach it just yet, but inquire first how Leighton Gillespie was able to reach the scene of the wreck so quickly. Did he hasten down from the Springs, which seem to have been some miles away, or was he in the vicinity of the accident when it occurred?"

"That is a question I have never heard answered. But I long ago concluded that he was not far from the place where the collision occurred, for he was seen there as soon as the smoke lifted. Why, what now? You seem moved--excited. Has any new idea been suggested to you?"

I exerted myself to speak calmly, but did not succeed.

"Yes," I cried, "a strange, a thrilling idea. What if the man who shared this engineer's awful ride was Leighton Gillespie, and what if he knew through all that headlong rush, that the wife he so much loved was in the train he was risking his life to save from destruction?"

XXV

A SUMMONS

The doctor's emotion equalled mine.

"It may have been so," he admitted. "There was always some unexplained mystery in connection with his presence at the wreck and the reticence he maintained in regard to it. If what you suggest is true and he was the man who shared the engineer's ride down those precipitous slopes to the rescue of a train on which he knew his wife to be, it will be easy enough for us to start a plea of mental derangement. No one could go through such an adventure, with its overpowering excitement and unspeakable suspense, without some injury to his mental or physical health. But it is hard to conceive how Leighton Gillespie should have been wandering on the mountain-side that day instead of taking the excursion with his wife."

"I don't advance this explanation as a fact, only as a possibility," I replied. "The shock of his wife's sudden death would be enough in itself to change the man."

"Yes, and it did change him; to that I can swear."

"How long a time elapsed after this catastrophe before you saw him?"

"Just two days. He telegraphed for me, and I went West to a.s.sist him in bringing home the remains of his young wife. I remember finding him in a strained, nervous condition; this was natural enough; but his worst symptoms disappeared after the funeral."

"Do you mind telling me where this funeral took place?"

"In a small place up the Hudson River, where the Gillespies have a country home. Mr. Gillespie carried his feeling against his daughter-in-law so far as not to wish to have her buried from his New York house."

"I suppose so; another reason, perhaps, why Leighton has never recovered from this blow. And little Claire? You have not mentioned her. Was she with her parents when this disastrous event occurred?"

"She was but an infant, and from her very birth was given into the charge of her grandfather. She never knew her mother."

It would have been a satisfaction to me to have learned the cause of the determined hostility on the part of a man seemingly so just as Mr.

Gillespie; but the doctor gave me no encouragement in this direction, and I merely said:

"We have made a start in case the necessity arises for proving him to be no longer responsible for his actions. But only a start. The direction taken by his mania is perilously like the excesses of a discouraged and reckless man."

"I am not so sure of that. In his sane mind, Leighton Gillespie is a great respecter of the rights of other people. I shall look into this subject, Mr. Outhwaite; I shall look into it at once. A half-hour's talk with him will satisfy me whether he is a victim of disease or the prey of unbridled pa.s.sions and murderous instincts."

The good doctor rose with every appearance of starting forth then and there.

"But you have had no dinner," I suggested.

"I want none."

I accompanied the doctor out, but parted with him at the corner. I would have given much for the privilege of going with him to the Gillespie house, but as this was not to be thought of, I resolutely turned towards my apartments, which were in quite a different direction.

How was it, then, that by the time the lights began to be lit in the streets I found myself circulating restlessly in the vicinity of the very house I had determined to avoid? Had the exciting incidents of the day been too much for me? It certainly looked so. Surely I had not wandered hither through any act of my own volition or for any definite purpose I could name. Yet now that I had been so led; now that I was within sight of the house where so important an interview was going on, I surely might be pardoned for taking advantage of this proximity to note the doctor when he came out and see, if possible, from his manner and bearing the result of a visit upon which such serious issues hung.

It had threatened storm all day, and during the last few minutes the atmosphere had become permeated with a drizzle which made further tramping over wet pavements undesirable. I therefore looked about for refuge, and perceiving a building in process of construction on the opposite side of the way, I glided amid its shadows, happy both at the protection it offered and the full view it gave me of the Gillespie front door.

That this was the act of one bent on espionage I am ready to acknowledge, but it was espionage undertaken in a good cause and for justifiable reasons. At all events I was engaged in inwardly persuading myself to this effect, when an event occurred which drew my attention from myself and fixed it with renewed interest on the door I was watching.

A boy of whose proximity I had had some previous intimation suddenly darted out from the s.p.a.ce behind me, and went flying across the street to the Gillespie house. He had a missive in his hand, and seemed anxious lest he should be caught and stopped.

This roused my curiosity, so that no detail of what followed escaped me. I noted the furtive way in which he thrust the letter into the unwilling hand of the old butler, who answered his frightened ring at the bell. Also the misgiving shake of the head with which the latter received it, and the doubtful looks they both cast at someone back in the hall. Who was this someone, and what lay behind old Hewson's agitated demeanour? The door closed on my curiosity, and I was left to ponder this new event. But not for long; scarcely had my eyes returned from following the escaping figure of the boy, when the door on the opposite side of the street unclosed again and Dr. Bennett came out.

Now, as I have taken pains to say, I had posted myself there in order to note how this gentleman looked on leaving Leighton Gillespie. But now that this opportunity had come, I not only failed to avail myself of it, but found my whole attention caught and my interest fully absorbed by a glimpse I had received of the latter gentleman standing back in the hall reading the letter I had just seen delivered in such a surrept.i.tious manner.

His att.i.tude, the gestures he unconsciously made, argued sudden and overwhelming emotion, an emotion so sudden and overwhelming that he could not conceal it, though he evidently would have been glad to do so, judging from the haste with which he thrust the letter in his pocket and turned--But here the door closed, as frequently happens at critical moments, and I found my eyes resting upon nothing more exciting than the figure of the doctor feeling his way with due care down the damp steps.

Had I not been witness both to the peculiar actions of the urchin who brought this letter, and to the strange manner in which Leighton received it, I might not have considered it decorous to make my presence known to the doctor at a moment and in a place so suggestive of a watch upon his movements. But as everything affecting Leighton was as interesting to this, his best friend, as it was to me, I crossed the street, and, with scant apology for the seeming intrusion, told the good doctor what had just come under my observation.

He seemed surprised, if not affected, by what I had to say. He had seen no letter and no evidences of disorder on the part of Leighton.

To be sure, he had left before any letter had been received.

"Indeed, you astonish me," he declared. "Seldom have I seen my young friend in a more equable frame of mind. He talked evenly and with discretion about the most exciting subjects; and, though I could wish him to have been more open, he showed a self-control hardly to be expected from a man placed in such a disturbing situation. The detective, who appeared to have full range of the house, hardly looked our way once. The letter which you say he received just as I left him must have contained very agitating news. I wonder if we will ever know what."
