We don't have much to say about this which gives us something in common with the author -- this is a re-run of how a young British novelist Graham Cameron (obviously you know who) came to the U.S. on a coast-to-coast promotion tour of his latest book -- from the A.B.A. in Washington to Fun City to Dallas to the coast, usually with a glass in his hand. Partly because he isn't able to put it on a pretty piece, Sally Weber, who's the author representative for a paperback house. Cameron is one of those inexhaustible word-and-punsmiths with boozy dreams of glory which he comes by out of his near, more literary, past. But here it is difficult to separate the commercial commonplaceness of American life from the chintzy vulgarity of this touring swinger who is supposed to be funnier than he is. . .RUN DON'T WALK.
