Dead Soul (Charlie Moon Series #8)

When tribal chairman Oscar Sweetwater asks Charlie Moon to look into the murder of a fellow Ute, Billy Smoke, Charlie agrees, but he doesn't expect to find anything. After all, Billy's boss, U.S. Senator Patch Davidson, nearly died in the ambush that night, too, so the FBI handled the investigation and it's still unsolved. The senator does happen to be Charlie's neighbor, though-their ranches share a fence line-so maybe the senator will be more forthcoming with him than he was with the FBI.
