"Bathurst," my Chief said, settling back in his chair, and eyeing me with great good humor, "I don't see but that you are getting on swimmingly, and I don't feel inclined to dictate much. Your Groveland affair is looking up. You may have as many men as you need to look after that business. As for Trafton, I think you and Carnes have made good use of your holiday. I think you have struck something rich, and that you had better remain there, and work it up; or, if you prefer to go to Groveland yourself, return there as soon as possible."

"I am glad to hear you talk as I think," I replied. "I believe that Trafton is ripe for an explosion, and I confess that, just at present, I am more interested in Trafton than in Groveland, besides----. In my report from Groveland, you may remember that I mentioned going to the station to fetch Miss Amy Holmes?"

"Yes."

"And that this young lady was accompanied on that day by a handsome young gentleman?"

"Yes."

"Well, I have since made the acquaintance of this young man."

"Ah!"

"At first I thought it only a coincidence, and dismissed the matter from my mind. Since I have heard Mrs. Ballou's story, a queer thought has entered my head."

"Explain."

"This young gallant, whom I first saw in the company of the runaway Miss Holmes, is Mr. Arch, or Archibald Brookhouse, of Trafton."

"I see," thoughtfully.

"And the initials following that alb.u.m verse are A. B."

"A. B.! Archibald Brookhouse! There _may_ be something in it, but should you feel justified in suspecting this young man as the possible author of _your_ anonymous letter?"

"If he is the writer of the alb.u.m lines, yes."

"What do you propose to do?"

"First," said I, "we must call in the dummy."

"Yes."

"Then I want a good man to go to Groveland in search of information. I want him to find out all that he can concerning the character of this Johnny La Porte, who attended school at Amora, and was a fellow-student with Nellie Ewing, Mamie Rutger, and Grace Ballou."

"Good."

"Then he must learn if any of the Groveland youths have become _lame_ since last Sunday, and if any of these same gentry was missing, or absent from home, during the night of the 17th, for, of course, Miss Amy Holmes being on his hands, the driver of the carriage which Mrs. Ballou routed that night must have been absent sometime, _if_ he belonged in the community. He surely had to dispose of Miss Holmes in some way."

"Do you think it probable that some Groveland Lothario was mixed up in this elopement business?"

"I think it not improbable. The first search was made, seemingly, upon the supposition that all Groveland was above suspicion, and that search failed. I intend to hold all Groveland Lotharios upon my list of suspected criminals until they are individually and collectively proven innocent."

"Quite right."

"On second thought we had better let the dummy remain until we have put a new man in the field; by this time he must know something about the people he is among. Who can you send to Groveland?"

"Wyman, I think."

"Capital; Wyman is good at this sort of thing. He had better present himself in person to our dummy, hear all that he can tell, and then deliver your letter of recall, and see him safely on his way to the city before he has time to open his mouth for the benefit of any one else."

"Very good; Wyman is at your disposal."

I drew toward me a large portfolio containing State and county maps. It lay at all times upon the office table, convenient for reference.

While I was tracing the eccentric course of a certain railroad, I could feel my Chief's eyes searching my countenance.

"Bathurst," he said, after some moments of silence, and leaning toward me as he spoke, "I believe you have a theory, or a suspicion, that is not entirely based upon Mrs. Ballou's revelation."

"You are right," I replied, "and it is a suspicion of so strange a sort that I almost hesitate to give it utterance, and yet I think it worthy of attention. I want to shadow this cavalier, Arch Brookhouse."

"Yes."

"I find by this map that the town of Amora is situated twenty-five miles from Groveland, and thirty miles from Trafton. Sharon, the nearest railroad communication with Groveland, is thirty miles from Amora, so that the distance from Trafton to Sharon is sixty miles, and the seminary town is midway between."

My Chief made a sign which meant "I comprehend; go on."

"Now, it is possible that accident or business brought Mr. Arch Brookhouse to Sharon, and that his meeting with Miss Holmes was quite accidental, and his attendance upon Miss Holmes and Grace Ballou merely a chance bit of gallantry. But when you consider that he seemed equally well known to both young ladies, that Sharon is a small town, and a dull one, and that Miss Holmes came from Amora that morning, is it not just as probable that Mr. Brookhouse traveled from Trafton to Amora for the purpose of escorting Miss Holmes to Sharon? Now, young men of our day are not much given to acts of courtesy extending over sixty miles of railroad; therefore, if Arch Brookhouse visited Sharon for the sole purpose of meeting these two young ladies, and basking in their society for a brief half hour, it is fair to presume that he is more than ordinarily interested in one of them."

"You are right, Bathurst; at least it would seem so."

"Now let me tell you all that I know concerning the Brookhouses."

Once more I gave a minute description of my first meeting with Arch Brookhouse, and of the second, when I recognized him at Trafton. Then I told him of my interview with the telegraph operator, of the telegram sent by Fred Brookhouse from New Orleans, and of the reply sent by Arch, and last I told him how Louis Brookhouse had come home, accompanied by another young man, _on the day after the attempted flight of Grace Ballou_, and how Dr. Bethel had been called upon to attend him, he having met with an accident.

My Chief stroked his chin thoughtfully.

"I see," he said, slowly, "you have some nice points of circ.u.mstantial evidence against these young gentlemen. How do you propose to use them?"

"First, I must know what motive took Arch Brookhouse to Sharon, and find out if either of the Brookhouse brothers have been students at Amora. I want therefore to send a second man to Amora."

"Very good."

"If I find that either, or both, of the younger brothers have been fellow-students with Grace Ballou, and the missing girls, then I shall wish to extend my search."

"To New Orleans?"

"To New Orleans."

"Is there anything more?"

"Yes; one thing. If Carnes goes to New Orleans I shall want a telegraph operator in Trafton."

"Then you wish to remain in Trafton?"

"Yes, and this takes me back to the other matter. I quite expected that a man like 'Squire Brookhouse would have called upon you for help. If he has employed men from either of the other offices, we can easily find out who they are."

"Easily."
