By the time I reached the city my arm, which needed fresh bandages, began to pain me, and I went straight to the office of a surgeon, well-known to fame, and to the detective service. He had bound up many a broken bone for our office, and we of the fraternity called him "Our Samaritan." Some of the boys, and, let me confess it, myself among the number, called him "Our old woman," as well, for, while he bandaged and healed and prescribed, he waged continued warfare upon our profession, or rather the dangers of it.

Of course, the country needed secret service men, and must have them, but there was an especial reason why each one of us should not be a detective. We were too young, or too old; we were too reckless, or we were cut out for some other career. In short, every patient that came under the hand of good Dr. Denham, became straightway an object of interest to his kindly old heart; and—strange weakness in a man of his cloth—he desired to keep us out of danger.

"So ho!" cried "our old woman," when I appeared before him with my bandaged arm, "here you are! I knew you'd be along soon. You've kept out of my clutches a good while. Arm, eh? Glad of it! I'll cut it off; I'll cut it off! That'll spoil one detective."

I laughed. We always laughed at the talkative soul, and he expected it.

"Cut it off, then," I retorted, flinging myself down in a chair and beginning to remove my sling. "I don't need a left arm to shoot the fellow that gave me this, and I'm bound to do that, you know."

"So! Got shot again? Go on, go on, sir! I'll have the pleasure of dissecting you yet. You'll come home dead some day, you scoundrel. Ah! here we are. Um! flesh wound, rear of arm, under side; close, pretty close, pret-ty close, sir!"

All this was jerked out in short breaths, while he was undoing and taking a first look at my arm. When the actual business of dressing commenced, "our old woman" was always silent and very intent upon the delicate task.

"Pity it wasn't a little worse," he sniffled, moving across the room and opening a case of instruments. "You chaps get off too easy; you don't come quite near enough to Death's door. There's Carnes, now; got a knife through his shoulder, and fretting and fuming because he can't put himself in a position to get another dig."

"Is Carnes in?"

"Yes. And was badly cut."

"Poor fellow! I'm sorry for that, but glad of the chance to see him; he's been on a long cruise."

"Well, I'm not so sure about his going on another. Now then."

And the doctor applied himself to business, and I sat, wincing sometimes, under his hand, but thinking through it all of Carnes.

He was the comique of the force; a man who was either loved or hated by all who knew him. No one could be simply indifferent to Carnes. He was a well-educated man, although he habitually spoke with a brogue. But I knew Carnes was not an Irishman; although he professed to have "hailed from Erin," he could drop the accent at pleasure and assume any other with perfect ease,—a feat rather difficult of accomplishment by a genuine Irishman.

Nobody knew much about Carnes; he had no confidants, although he had his favorites, one of whom I chanced to be.

He was older than myself by ten years, but when the mood seized him, could be younger by twenty. He had been absent from the office for nearly a year, and I mentally resolved that, after making my report and attending to business, I would lose no time in seeing him.

Under the skilled hand of Dr. Denham my arm was soon dressed and made comfortable. It would be well in a fortnight, the good doctor assured me, and then as soon as I could, I withdrew from his presence and his customary fire of raillery and questions, and stopping only to refresh myself at a restaurant by the way, hastened on toward our office, where I was soon closeted with my Chief.

As usual, he made no comments, asked no questions, when I dawned upon him thus unexpectedly. He never made use of unnecessary words. He only turned out one or two of the force who were lounging there, waiting his pleasure to attend to less important business, saw that the doors were closed and the outer office properly attended, and then seating himself opposite me at the desk, said quietly:

"Now, Bathurst?"

I was well accustomed to this condensed way of doing things, and it suited me. In a concise manner matching his own, I put him in possession of the facts relating to the Groveland case, and then I made a discovery. After relating how I had received the anonymous letter I produced my pocket-book, where I supposed it to be, and found it missing! It was useless to search; the letter was not in my pocket-book, neither was it on my person.

"Well!" I said, when fully convinced that the letter was certainly not in my possession, "here's another complication. I've been robbed and—I know who did it!"

My companion made no comment, and I continued:

"The letter was of no vital importance; I will finish my story and then you will know what has become of it."

I told the rest; of my ride upon Mrs. Ballou's colt, of the pistol shot, my runaway steed, and my subsequent interview with Mrs. Ballou. How she had dressed my wound, how the circumstances had compelled me to confide in her, and how she had risen to the occasion, and driven me to the station at half-past three in the morning, and I finished by saying:

"Now it looks to me as if Mrs. Ballou had stolen my letter, and if so, one might take that fact and the one that Nellie Ewing was never seen after leaving her house, and count it as strong circumstantial evidence; but, that kind of evidence won't convince me that Mrs. Ballou is implicated in the crime or the mystery. When I told her of the printed letter, I saw her eyes gleam; and when she asked to see the document I read anxiety in her face. I am sure she took the letter, and I think she has a suspicion of some sort; but if she has the letter she will return it."

My chief made no comment on all that I had told him; he picked up a paper weight and laid it down again with great precision, then he put all my story "on the shelf," as we were wont to express it, by asking abruptly:

"What are you going to do next?"

The question did not surprise me. He was not in the habit of offering much advice to such operatives as he trusted with delicate cases, for he never trusted a man until he felt full confidence in his skill and integrity. But when we desired to consult with him, he entered into the study of the case with animation and zeal; and then, and then only, did he do a full share of the talking.

"Going to send them a 'dummy,' if we can find one with the grit to face the chances. They must suppose me entirely out of the business."

"Yes."

"I want an extraordinary dummy, too; a blusterer."

"Wait," interrupted my companion, beginning to smile, "I have got just the animal. When do you want to see him?"

"As soon as possible; I want him in the field at once."

"Very good. This fellow came here yesterday, and he's the greatest combination of fool and egotist I ever saw. Knows he was born for a detective and is ready to face a colony of desperadoes; there is no limit to his cheek and no end to his tongue. If you want a talkative fool he'll do."

"Well," I replied, "that's what I want, but the man must not be quite destitute of courage. I don't think that the party or parties will make another attack upon a fresh man, and yet they may; and this dummy must remain there quite alone until the rascals are convinced that he has no confederates. There is a keen brain at the bottom of this Groveland mischief. I mean to overreach it and all its confederates, for I believe there must be confederates; and, sir, I don't believe those girls have been murdered."

"No?"

"No. But I want our dummy to act on the supposition that they have been. This will ease the vigilance of the guilty parties, and when they are off their guard, our time will come. Where is Carnes?"

My companion was in full sympathy with my abrupt change of the subject, and he answered, readily:

"At his old rooms. Carnes had a bad cut, but he is getting along finely."

"Is he? The doctor gave me the idea that he was still in a doubtful condition."

"Stuff," giving a short laugh, "some of his scarey talk; he told me that Carnes would be about within two weeks. Carnes did some good work in the West."

"He is a splendid fellow; I must see him to-night. But about our dummy: when can you produce him?"

"Will to-morrow do? say ten o'clock."

"It must be later by an hour; the doctor takes me in hand at ten."

"Eleven, then. I will have him here, and you'll find him a jewel."

"Very good," I said, rising, and taking up my hat, "any message to send to Carnes? I shall see him to-night."

"Look here," turning upon me suddenly, "you are not to go to Carnes for any purpose but to see him. You must not talk to him much, nor let him talk; the doctor should have told you that. He is weak, and easily excited. It's bad enough to have two of my best men crippled and off at once; you must not retard his recovery. Carnes is as unruly as a ten-year old, now."

I laughed; I could see just how this whimsical comrade of mine would chafe under his temporary imprisonment.

"I won't upset the old fellow," I said, and took my leave.
