Of necessity (unless Willis provides a Holmesian resurrection), this will be the last novel about the career of that tough, loudmouthed Rosie Carr, whose rise form London waif-hood has been traced in Spring at the Winged Horse (1982) and The Green Leaves of Summer (1989). Here, Rosie--cor'!--is elected in 1930 to Parliament. At the start, Rose is married to kind Ken Coleson (in spite of her doubts), who's a weak reed compared to Rosie's old flame, traveling man Jack Cameron (The Green Leaves...). But Rosie, still a partner in a booming retail business, is as busy as a hornet, even on her honeymoon, when she is assaulted by Italian fascists. After she's elected as an M.P. for the Labour party, she will: be present at a British Black Shirt meeting (son Eddie is there to heckle) and earn the media nickname of ``Red Rose''; travel to Geneva with a delegation; plead for help for Jewish victims in Germany; and rescue a Jewish family herself. Along the way, there are also domestic problems--daughter Val wants to be an actress, and Ken has a dreadful secret (though Rosie will manage to extricate him from blackmail). As for love, there's a brief affair with a colleague, and Jack returns for a last fabulous flight. All this before the chill winds of illness waft Rosie away. Rosie as M.P. is a bit much, but followers of her sentimental, soapy adventures will want to be in on the last spin.
