David Stuart Horner (1926) painted by Philip Steegman
David Stuart Horner (29 July 1900 – 1983) was a crime fiction novelist and the longtime partner of Osbert Sitwell.
According to John Pearson, Sitwells' biographer, "David dressed superbly, had an amusing line of gossip about all the best people, which he recounted in an engagingly basso profundo voice, and after leaving Cambridge was soon floating, as unattached, good-looking, upper-class young Englishmen could float in those more gentle, far-off days, through a rarely failing world of dinner-parties, long weekends and holidays abroad. He was the perfect guest, the ideal ornament for any party, charming to women and agreeable to men, better connected and far better read than the usual run of gilded social butterflies, and equally at home in the best society in Paris or in London."
