A columnist on the Dallas News. Edwin Shrake has written an intermittently impressive novel revealing in its portrait of Texas as it is today. With bright ishonor, Texans die for money but not for love, as two generations face each other in a struggle for power. There are the arrived men (and the failures) of middle age who have made their own way in the world, confronted by the youths from a background of affluence and shifting values, who only now are reaching the age of disillusion. The major scene of confrontation is a party to rival Gatsby's--three days of unbroken, beautiful guzzling financed by oilionheirs-- at which a man with a gun is in attendance...a gun which must be fired. The greatest merit of the book is its dialogue, which has a thwanging, twanging Texan uniqueness-- although the reader sometimes chokes on forcefed information. The descriptive matter falls short. If derivations show, this is still a fine tale with pedestrian moments.
