In VN’s novel Ada (1969) Van tells Lucette (Van’s and Ada’s half-sister) who looks at Lenore Colline (the movie actress who resembles Ada) that cats do not stare at stars:
Mr Sween, lunching with a young fellow who sported a bullfighter’s sideburns and other charms, bowed gravely in the direction of their table; then a naval officer in the azure uniform of the Gulfstream Guards passed by in the wake of a dark, ivory-pale lady and said: ‘Hullo Lucette, hullo, Van.’
