A second book from one of the young English novelists (Lucky Jim was the first) continues his prodding of pomp and many circumstances, of upper class apings and ossified institutionalism. This takes the form of Welsh librarian, John Lewis' Japes — in his posturings, his treatment of library card holders and the snooks he cocks at the local anglicized bourgeoisie. The chance for advancement is desirable to free him, his wife Jean and their baby, Eira, from their tumbled living and the hopes held out by Elizabeth Gruffydd-Williams are promising — until he learns it is a fiddle for her husband, Vernon, to use him only to do an enemy in the eye. But before he has gleefully turned down the Job, he and Elizabeth have had their roll, after some mixed up meetings, and Jean has turned on him. So it's back to marriage and a new Job in another town- with his inhibitions well loosed to his satisfaction. It's not a sure bet that British acclaim — and vanguard American criticism will overcome that uncertain American market.
