And the most appealing of novels -- even more so than her first, The Single Girl who didn't have quite the vulnerability of Sally Bridger, divorced after eight years and the mother of Charlie, six, whom she really can't handle. He keeps rebuffing her and increasing her sense of guilt and loneliness. Not that she misses the departed Simon -- a regulated, antiseptic type (""a mouthful of Listerine sent on a statutory half-dozen revolutions"" twice a day) -- pompous Simon, now married to a young woman from the post office who looks 'very clean in her plastic pinafore. Even with Charlie Sally is altogether alone until he picks upone Joe Sargent (at the fun fair) whom they both like, perhaps too much. Joe has already been appropriated by Diane who works for her aunt's ""Marriage and Friendship arranged in Strictest Confidence"" bureau and she knows all the answers. Even how to secure Joe at the end -- after Sally flips out totally and tries to commit suicide. . . . Mary Danby writes with a true touch for things as they are, as they might have been, as they should have been. A conspicuously convincing and fetching light novel -- to make your day, or evening.
