If this were a scene in a movie, you'd know right away that it was the scene about the actress' last day in town. Jacqueline Bisset's two-room suite at the Sheraton Plaza was scattered with props for her departure. The bedroom floor was lined with trunks and suitcases, their lids tilted open, clothes tumbling out of them. Leaning against the wall in the living room was one of those big cartoonist's caricatures showing Jackie with a giant head balanced on top of a tiny body. It said, "Good Luck, Jackie!" and it was signed by all the members of the cast and crew of her latest film.
