But tattoo had not sounded that still and starlit evening when a strange story was in circulation about the post, brought up from the trader's store by pack-train hands who said they were there when Mr. Blakely came in and asked for Hart—"wanted him right away, bad," was the way they put it. Then it transpired that Mr. Blakely had found no sport at bug-hunting and had fallen into a doze while waiting for winged insects, and when he woke it was to make a startling discovery—his beautiful Geneva watch had disappeared from one pocket and a flat note case, carried in an inner breast pocket of his white duck blouse, and containing about one hundred dollars, was also gone. Some vagrant soldier, possibly, or some "hard-luck outfit" of prospectors, probably, had come upon him sleeping, and had made way with his few valuables. Two soldiers had been down stream, fishing for what they called Tonto trout, but they were looked up instantly and proved to be men above suspicion. Two prospectors had been at Hart's, nooning, and had ridden off down stream toward three o'clock. There was a clew worth following, and certain hangers-on about the trader's, "layin' fer a job," had casually hinted at the prospect of a game down at Snicker's—a ranch five miles below. Here, too, was something worth investigating. If Blakely had been robbed, as now seemed more than likely, Camp Sandy felt that the perpetrator must still be close at hand and of the packer or prospector class.
But before the ranks were broken, after the roll-call, then invariably held at half-past nine, Hart came driving back in a buckboard, with a lantern and a passenger, the latter one of the keenest trailers among the sergeants of Captain Sanders' troop, and Sanders was with the major as the man sprang from the wagon and stood at salute.
"Found anything, sergeant?" asked Plume.
"Not a boot track, sir, but the lieutenant's own."
"No tracks at all—in that soft sand!" exclaimed the major, disappointed and unbelieving. His wife had come slowly forward from within doors, and, bending slightly toward them, stood listening.
"No boot tracks, sir. There's others though—Tonto moccasins!"
Plume stood bewildered. "By Jove! I never thought of that!" said he, turning presently on his second troop commander. "But who ever heard of Apaches taking a man's watch and leaving—him?"
"If the major will look," said the sergeant, quietly producing a scouting notebook such as was then issued by the engineer department, "I measured 'em and made rough copies here. There was two, sir. Both came, both went, by the path through the willows up stream. We didn't have time to follow. One is longer and slimmer than the other. If I may make so bold, sir, I'd have a guard down there to-night to keep people away; otherwise the tracks may be spoiled before morning."
"Take three men and go yourself," said the major promptly. "See anything of any of the lieutenant's property? Mr. Hart told you, didn't he?" Plume was studying the sergeant's pencil sketches, by the light of the trader's lantern, as he spoke, a curious, puzzled look on his soldierly face.
"Saw where the box had lain in the sand, sir, but no trace of the net," and Sergeant Shannon was thinking less of these matters than of his sketches. There was something he thought the major ought to see, and presently he saw.
"Why, sergeant, these may be Tonto moccasin tracks, but not grown men's. They are mere boys, aren't they?"
"Mere girls, sir."
There was a sound of rustling skirts upon the bare piazza. Plume glanced impatiently over his shoulder. Mrs. Plume had vanished into the unlighted hallway.
"That would account for their taking the net," said he thoughtfully, "but what on earth would the guileless Tonto maiden do with a watch or with greenbacks? They wouldn't dare show with them at the agency! How far did you follow the tracks?"
"Only a rod or two. Once in the willows they can't well quit them till they reach the shallows above the pool, sir. We can guard there to-night and begin trailing at dawn."
"So be it then!" and presently the conference closed.
Seated on the adjoining gallery, alone and in darkness, stricken and sorrowing, a woman had been silently observant of the meeting, and had heard occasional snatches of the talk. Presently she rose; softly entered the house and listened at a closed door on the northward side—Captain Wren's own room. An hour previous, tortured between his own thoughts and her well-meant, but unwelcome efforts to cheer him, he had begged to be left alone, and had closed his door against all comers.
Now, she as softly ascended the narrow stairway and paused for a moment at another door, also closed. Listening a while, she knocked, timidly, hesitatingly, but no answer came. After a while, noiselessly, she turned the knob and entered.
A dim light was burning on a little table by the white bedside. A long, slim figure, white-robed and in all the abandon of girlish grief, was lying, face downward, on the bed. Tangled masses of hair concealed much of the neck and shoulders, but, bending over, Miss Wren could partially see the flushed and tear-wet cheek pillowed on one slender white arm. Exhausted by long weeping, Angela at last had dropped to sleep, but the little hand that peeped from under the thick, tumbling tresses still clung to an odd and unfamiliar object—something the older woman had seen only at a distance before—something she gazed at in startled fascination this strange and solemn night—a slender, long-handled butterfly net of filmy gauze.
CHAPTER IV
A STRICKEN SENTRY
entry duty at Camp Sandy along in '75 had not been allowed to bear too heavily on its little garrison. There was nothing worth stealing about the place, said Plume, and no pawn-shop handy. Of course there were government horses and mules, food and forage, arms and ammunition, but these were the days of soldier supremacy in that arid and distant land, and soldiers had a summary way of settling with marauders that was discouraging to enterprise. Larceny was therefore little known until the law, with its delays and circumventions, took root in the virgin soil, and people at such posts as Sandy seldom shut and rarely locked their doors, even by night. Windows were closed and blanketed by day against the blazing sun and torrid heat, but, soon after nightfall, every door and window was usually opened wide and often kept so all the night long, in order that the cooler air, settling down from mesa and mountain, might drift through every room and hallway, licking up the starting dew upon the smooth, rounded surface of the huge ollas, the porous water jars that hung suspended on every porch, and wafting comfort to the heated brows of the lightly covered sleepers within. Pyjamas were then unknown in army circles, else even the single sheet that covered the drowsing soldier might have been dispensed with.
Among the quarters occupied by married men, both in officers' row and Sudsville under the plateau, doors were of little account in a community where the only intruder to be feared was heat, and so it had resulted that while the corrals, stables, and storehouses had their guards, only a single sentry paced the long length of the eastward side of the post, a single pair
