Lowell was frankly worried as he sped away from the agency with Plenty Buffalo and the interpreter. Every crime, large or small, which occurred near the reservation, and which did not carry its own solution, was laid to Indians. Here was something which pointed directly to Indian handiwork, and Lowell in imagination could hear a great outcry going up.

Plenty Buffalo gave little more information as the car swayed along the road that led off the reservation.

"He says he was off the reservation trailing Jim McFann," remarked the interpreter. "He thought Jim was going along the road to Talpers's store, but Plenty Buffalo was mistaken. He did not find Jim, but what he did find was this man who had been killed."

"Jim McFann isn't a bad fellow at heart, but this bootlegging and trailing around with Bill Talpers will get him in trouble yet," replied the agent. "He's pretty clever, or Plenty Buffalo's men would have caught him long before this."

They were approaching Talpers's store as the agent spoke. The store was a barn-like building, with a row of poplars at the north, and a big cottonwood in front. A few houses were clustered about. Bill Talpers, store-keeper and postmaster, looked out of the door as the automobile went past. Generally there were Indians sitting in front of the store, but to-day there were none. Plenty Buffalo volunteered the information that there had been a "big sing" on a distant part of the reservation which had attracted most of the residents from this neighborhood. Talpers was seen running out to his horse, which stood in front of the store.

"He'll be along pretty soon," said the agent. "He knows there's something unusual going on."

The road over which the party was traveling was sometimes called the Dollar Sign, for the reason that it wound across the reservation line like a letter S. After leaving White Lodge, which was off the reservation, any traveler on the road crossed the line and soon went through the agency. Then there was a curve which took him across the line again to Talpers's, after which a reverse curve swept back into the Indians' domain. All of which was the cause of no little trouble to the agent and the Indian police, for bootleggers found it easy to operate from White Lodge or Talpers's and drop back again across the line to safety.

Another ten miles, on the sweep of the road toward the reservation, and the automobile was sighted. The body was found, as Plenty Buffalo had described it. The man had been murdered—that much was plain enough.

"Buckshot, from a sawed-off shotgun probably," said the agent, shuddering.

Whoever had fired the shot had done his work with deadly accuracy. Part of the man's face had been carried away. He had been well along in years, as his gray hair indicated, but his frame was sturdy. He was dressed in khaki—a garb much affected by transcontinental automobile tourists. The car which he had been driving was big and expensive.
