Another soft-centered entertainment of light mystery and lighter romance in London, where Mme. Landini, a once formidable diva, whose autobiography editor Rodney is publishing, literally screeched to a halt in mid-memoir. Some fairly casual sleuthing reveals that Mme. Landini had been spooked by the watch of Nicola, her pretty secretary. And did that have something to do with the disappearance, years ago, of the singer's husband, who was last seen on shipboard with an armload of flowers? By the time this tangle is gently untangled, Rodney and Nicola have discovered pleasant things about one another and Rodney's charmingly scatterbrained sister hooks her man. For the lounge library.
