"Yis, sah.

"Then it couldn't have been Mr. Cullen, Jim," I declared, "for I found him up at the other end of the car."

"Tell you it wuz, Mr. Gordon," Jim insisted. "I done seen his face clar in de light, and he done go into Mr. Cullen's car whar de old gentleman wuz sittin'."

That set me whistling to myself, and I laughed to think how near I had come to giving nitroglycerin to a fellow who was only shamming heart-failure; for that it was Frederic Cullen who had climbed on the car I hadn't the slightest doubt, the resemblance between the two brothers being quite strong enough to deceive any one who had never seen them together. I smiled a little, and remarked to myself, "I think I can make good my boast that I would catch the robbers; but whether the Cullens will like my doing it, I question. What is more, Lord Ralles will owe me a bottle." Then I thought of Madge, and didn't feel as pleased over my success as I had felt a moment before.

By nine o'clock the posse and I were in the saddle and skirting the San Francisco peaks. There was no use of pressing the ponies, for our game wasn't trying to escape, and, for that matter, couldn't, as the Colorado River wasn't pa.s.sable within fifty miles. It was a lovely moonlight night, and the ride through the pines was as pretty a one as I remember ever to have made. It set me thinking of Madge and of our talk the evening before, and of what a change twenty-four hours had brought. It was lucky I was riding an Indian pony, or I should probably have landed in a heap. I don't know that I should have cared particularly if a prairie-dog burrow had made me dash my brains out, for I wasn't happy over the job that lay before me.

We watered at Silver Spring at quarter-past twelve. From that point we were clear of the pines and out on the plain, so we could go a better pace. This brought us to the half-way ranch by two, where we gave the ponies a feed and an hour's rest. We reached the last relay station just as the moon set, about three-forty; and, as all the rest of the ride was through coconino forest, we held up there for daylight, getting a little sleep meanwhile.

We rode into the camp at the Grand Canon a little after eight, and the deserted look of the tents gave me a moment's fright, for I feared that the party had gone. Tolfree explained, however, that some had ridden out to Moran Point, and the rest had gone down Hance's trail.

So I breakfasted and then took a look at Albert Cullen's Winchester.

That it had been recently fired was as plain as the Grand Canon itself; throwing back the bar, I found an empty cartridge sh.e.l.l still oily from the discharge. That completed the tale of seven shots. I didn't feel absolutely safe till I had asked Tolfree if there had been any shooting of echoes by the party, but his denial rounded out my chain of evidence.

Telling the sheriff to guard the bags of the party carefully, I took two of the posse and rode over to Moran's Point. Sure enough there were Mr. Cullen, Albert, and Captain Ackland. They gave a shout at seeing me, and even before I had reached them they called to know how I could come so soon, and if I had caught the robbers. Mr. Cullen started to tell his pleasure at my rejoining the party, but my expression made him pause, and it seemed to dawn on all three that the Winchester across my saddle, and the cowboys' hands resting nonchalantly on the revolvers in their belts, had a meaning.

"Mr. Cullen," I explained, "I've got a very unpleasant job on hand, which I don't want to make any worse than need be. Every fact points to your party as guilty of holding up the train last night and stealing those letters. Probably you weren't all concerned, but I've got to go on the a.s.sumption that you are all guilty, till you prove otherwise."

"Aw, you're joking," drawled Albert.

"I hope so," I said, "but for the present I've got to be English and treat the joke seriously."

"What do you want to do?" asked Mr. Cullen.

"I don't wish to arrest you gentlemen unless you force me to," I said, "for I don't see that it will do any good. But I want you to return to camp with us."

They a.s.sented to that, and, single file, we rode back. When there I told each that he must be searched, to which they submitted at once.

After that we went through their baggage. I wasn't going to have the sheriff or cowboys tumbling over Miss Cullen's clothes, so I looked over her bag myself. The prettiness and daintiness of the various contents were a revelation to me, and I tried to put them back as neatly as I had found them, but I didn't know much about the articles, and it was a terrible job trying to fold up some of the things. Why, there was a big pink affair, lined with silk, with bits of ribbon and lace all over it, which nearly drove me out of my head, for I would have defied mortal man to pack it so that it shouldn't muss. I had a funny little feeling of tenderness for everything, which made fussing over it all a pleasure, even while I felt all the time that I was doing a sneak act and had really no right to touch her belongings. I didn't find anything incriminating, and the posse reported the same result with the other baggage. If the letters were still in existence, they were either concealed somewhere or were in the possession of the party in the Canon. Telling the sheriff to keep those in the camp under absolute surveillance, I took a single man, and saddling a couple of mules, started down the trail.

We found Frederic and "Captain" Hance just dismounting at the Rock Cabin, and I told the former he was in custody for the present, and asked him where Miss Cullen and Lord Ralles were. He told me they were just behind; but I wasn't going to take any risks, and, ordering the deputy to look after Cullen, I went on down the trail. I couldn't resist calling back--

"How's your respiration, Mr. Cullen?"

He laughed, and called, "Digitalis put me on my feet like a flash."

"He's got the most brains of any man in this party," I remarked to myself.

The trail at this point is very winding, so that one can rarely see fifty feet in advance, and sometimes not ten. Owing to this, the first thing I knew I plumped round a curve on to a mule, which was patiently standing there. Just back of him was another, on which sat Miss Cullen, and standing close beside her was Lord Ralles. One of his hands held the mule's bridle; the other held Madge's arm, and he was saying, "You owe it to me, and I will have one. Or if--"

I swore to myself, and coughed aloud, which made Miss Cullen look up.

The moment she saw me she cried, "Mr. Gordon! How delightful!" even while she grew as red as she had been pale the moment before. Lord Ralles grew red too, but in a different way.

"Have you caught the robbers?" cried Miss Cullen.

"I'm afraid I have," I answered.

"What do you mean?" she asked.

I smiled at the absolute innocence and wonder with which she spoke, and replied, "I know now, Miss Cullen, why you said I was braver than the Britishers."

"How do you know?"

I couldn't resist getting in a side-shot at Lord Ralles, who had mounted his mule and sat scowling. "The train-robbers were such thoroughgoing duffers at the trade," I said, "that if they had left their names and addresses they wouldn't have made it much easier. We Americans may not know enough to deal with real road agents, but we can do something with amateurs."

"What are we stopping here for?" snapped Lord Ralles.

"I'm sure I don't know," I responded. "Miss Cullen, if you will kindly pa.s.s us, and then if Lord Ralles will follow you, we will go on to the cabin. I must ask you to keep close together."

"I stay or go as I please, and not by your orders," a.s.serted Lord Ralles, snappishly.

"Out in this part of the country," I said calmly, "it is considered shocking bad form for an unarmed man to argue with one who carries a repeating rifle. Kindly follow Miss Cullen." And, leaning over, I struck his mule with the loose ends of my bridle, starting it up the trail.

When we reached the cabin the deputy told me that he had made Frederic strip and had searched his clothing, finding nothing. I ordered Lord Ralles to dismount and go into the cabin.

"For what?" he demanded.

"We want to search you," I answered.

"I don't choose to be searched," he protested. "You have shown no warrant, nor--"

I wasn't in a mood toward him to listen to his talk. I swung my Winchester into line and announced, "I was sworn in last night as a deputy-sheriff, and am privileged to shoot a train-robber on sight.

Either dead or alive, I'm going to search your clothing inside of ten minutes; and if you have no preference as to whether the examination is an ante or post-mortem affair, I certainly haven't."

That brought him down off his high horse--that is, mule--and I sent the deputy in with him with directions to toss his clothes out to me, for I wanted to keep my eye on Miss Cullen and her brothers, so as to prevent any legerdemain on their part.

One by one the garments came flying through the door to me. As fast as I finished examining them I pitched them back, except--Well, as I have thought it over since then, I have decided that I did a mean thing, and have regretted it. But just put yourself in my place, and think of how Lord Ralles had talked to me as if I was his servant, had refused my apology and thanks, and been as generally "nasty" as he could, and perhaps, you won't blame me that, after looking through his trousers, I gave them a toss which, instead of sending them back into the hut, sent them over the edge of the trail. They went down six hundred feet before they lodged in a poplar, and if his lordship followed the trail he could get round to them, but there would then be a hundred feet of sheer rock between the trail and the trousers. "I hope it will teach him to study his Lord Chesterfield to better purpose, for if politeness doesn't cost anything, rudeness can cost considerable," I chuckled to myself.

My amus.e.m.e.nt did not last long, for my next thought was, "If those letters are concealed on any one, they are on Miss Cullen." The thought made me lean up against my mule, and turn hot and cold by turns.

A nice situation for a lover!

CHAPTER VI

THE HAPPENINGS DOWN HANCE'S TRAIL

Miss Cullen was sitting on a rock apart from her brother and Hance, as I had asked her to do when I helped her dismount. I went over to where she sat, and said, boldly--

"Miss Cullen, I want those letters."

"What letters?" she asked, looking me in the eyes with the most innocent of expressions. She made a mistake to do that, for I knew her innocence must be feigned, and so didn't put much faith in her face for the rest of the interview.

"And what is more," I continued, with a firmness of manner about as genuine as her innocence, "unless you will produce them at once, I shall have to search you."

"Mr. Gordon!" she exclaimed, but she put such surprise and grief and disbelief into the four syllables that I wanted the earth to swallow me then and there.
