The new thriller in the #1 New York Times�bestselling Isaac Bell series from grand master of adventure Clive Cussler.

As Van Dorn private detective Isaac Bell strives to land a government contract to investigate John D. Rockefeller�s Standard Oil monopoly, the case takes a deadly turn. A sniper begins murdering opponents of Standard Oil, and soon the assassin�shooting with extraordinary accuracy at seemingly impossible long range�kills Bell�s best witness, a brave and likable man. Then the shooter detonates a terrible explosion that sets the victim�s independent refinery ablaze.

Bell summons his best detectives to scour the site of the crime for evidence. Who is the assassin and for whom did he kill? But the murders�shootings, poisonings, staged accidents�have just begun as Bell tracks his phantom-like criminal adversary from the �oil fever� regions of Kansas and Texas to Washington, D.C., to the tycoons� enclave of New York, to Russia�s war-torn Baku oil fields on the Caspian Sea, and back to America for a final, desperate confrontation. And this one will be the most explosive of all.
