Kelly's Eye

Secrecy is broken after a Mogul rig called Kelly's Eye, drilling far out in the North Sea, finds a small pocket of oil. It proves to be worthless, but someone from the rig has leaked the news to Press and television. When Brian Stead, Mogul's director of operations, orders the culprit to be found and sacked, it is Peter Thornton, the manager of North Sea operations, who has to investigate both on shore and aboard the rig itself.
