Eight men had gone with Sergeant Stowell as escort to the paymaster when, nearly four weeks earlier, he had set forth on his trip. Then the little iron safe was full of money. Seven men had come back with him, when, as the safe was well nigh empty, the paymaster said he hardly needed an escort. Of the eight who started, four were "casuals" who belonged to companies stationed at Fort Frayne, well up in the Indian country, and there they remained when the duty was over. Of the seven who came with Stowell, three belonged at Fort Frayne, a corporal and two men of Captain Raymond's troop, and they came fortified with the orders of their post commander, a copy of which was now in Barker's hands.
"What I don't understand," said the colonel, whirling his chair to the right about and addressing the paymaster, "is how or why those men should be down here."
"It seems simple," answered Scott, placidly, he being entirely independent of the post commander. "From Frayne I had to go to the cantonments up along the Big Horn, and we doubled the size of the escort accordingly. When we got back there these three were permitted to come all the way, whether to buy Christmas things for the Frayne folk, or for affairs of their own, I didn't inquire."
"To whom did you assign them for rations and quarters?" demanded the colonel, of Barker.
"Captain Snaffle, sir—'C' Troop."
"Are they there?—the others, at least?"
"Corporal Watts and Trooper Ames are there, sir. Trooper Rawdon, as you know, is not. He has not been seen about the quarters since some time last evening. Moreover, the few personal belongings he had are gone."
Again a pause. Then presently: "You arrested Kelly, I see, the man who was on Number Five."
"Yes, sir. Both Doctor Schuchardt and the steward said his sickness was due to drink. The sergeant and corporal-of-the-guard are willing to swear he was perfectly sober when they stationed him. The men say he hadn't touched a drop of liquor for a month. He must have drunk after he was posted as sentry, for he vomited whiskey at the hospital. I believe he was doped."
"That he could get whiskey anywhere along back of the officers' quarters," said the colonel, reflectively as well as reflecting, "is not improbable. That it should have been doped, judging from the way one or two have misbehaved, is not impossible. Captain Snaffle's cook, it seems, was indulging some of her friends with a surreptitious supper, at his expense. That, very possibly, is how Kelley came to grief. The others seem to have hidden their tracks thus far." Then, as though with sudden resolution, he turned abruptly again.
