CAMPBELL'S KINGDOM BY HAMMOND INNES IN SASOLBURG

Campbell's Kingdom by Hammond Innes   At 36, Bruce Wetheral, a London insurance clerk, finds he hasn't much time to live. A few hours later he also learns that he has become sole heir to his grandfather's failing Canadian enterprise.   Campbell's land--perched at feet in the Canadian Rockies--may contain vast resources of oil. The old man's partners offer him a moderate sum for control. He declines the offer and launches his own search for Rocky Mountain "Black Gold."   "The art of writing thoroughly well-documented and ably-written thrillers is perfectly understood by Innes, whose work stands in a class by itself." --V.S. Pritchett           SOME WEAR AND TEAR
