The victim, well dressed but stripped of identification, is found at the edge of the vast Jicarilla Apache natural gas field just inside the jurisdiction of the Navajo Tribal Police, presenting Sergeant Jim Chee with a complex puzzle.
Why did the Washington office of the FBI snatch custody of this case from its local agents, cover it with secrecy, and call it a hunting accident? What was the victim seeking among the maze of pipelines and pumping stations in America's largest gas field? Was he investigating the embezzlement of billions of dollars from the Indian Tribal royalty trust in the Department of the Interior?
On a level nearer to Chee's heart, did photographs Bernie Manuelito had taken on an exotic game ranch near the Mexican border reveal something connected with this crime? Had Bernie, once a member of his squad but now a rookie Border Patrol Officer, put herself in terrible danger?
Lieutenant Joe Leaphorn helps Chee connect the lines on a dusty old map to find the answers -- and the Sinister Pig -- among the great Scimitar-Horned Oryx grazing on the historic old Tuttle Ranch.
