A gentle, deft and witty English novel catechizes science (reason) vs. poetry (instinct) in rondelay and science is represented by pretty, young Margaret Dawling, a metallurgist. In the spirit of true scientific curiosity she decides to read all the poets from A to Z. At H, she happens to meet the poet she is reading-Hugh Humble- and through him a number of other poets. This world has a disastrous effect upon her and upon several of her colleagues. She breaks off her engagement with a young scientist, has an affair with another who had happened to have written some poems as a take-off, and was later dismayed to find them widely successful proving- perhaps- that instincts are as important as reason. And instinct has long since toppled Margaret. She becomes pregnant, rejects his decent but unloving offer of marriage, and finally settles for a happier domesticity as offered by another poet.... Do not reason, it's to be enjoyed as a light diversion of contrasts.
