Last one: 5D Sandra's car (7) I have S-L-M-N. Only thing that will fit is Solomon. Possibly because I don't have a TV, the only 'Sandra' I can think of is the Liver Bird! Any bright ideas, folks?
I have STEAD for 5A - clue - State Case. If 5D is HILLMAN (and I see there is an actress Sandra Hillman, the minx!), then that makes 5A H-E-D, so what on earth is that?
