Allan Turpin has set his Box in the London of the '20's, ""the beginning of what for want of a better term we must call the Modern Age,"" but his divertissement is definitely a period piece (more Edwardian than modern). His narrator is a very serious young man, his heroine a young woman who all unconsciously falls in with the temper of the times. Beattle Chancellor is twenty-six, married to an incurably romantic husband who still is not ""interested"" in her but longs for the cricket fields of his public school. It is she who steps out, shingles her hair in the newest mode, falls in love with a car salesman and commits adultery in her own home. When her husband purposefully discovers them, the young Chancellors separate, then divorce--another novel move in an evolving society. The narrator's flush of first love for Beattie is eventually revealed and acknowledged though he never has his day. The Box itself is the reviewer's station at the theatre variously occupied by the Chancellor brothers and at the last Beattie's new husband, Harcourt-Wilson. The Box is also an accessory to a passing, rather passe pleasantry.
