I'd like you to Take Something Down, Miss Dixon...Rosie's decision to get something solid behind her is to be applauded, even if her experiences at the 'Lft SI O Fwt' - or Learnfast School of Fastwriting, as it is known to backward pupils, is an unhappy pointer to the future.But is a smart London advertising agency the right niche for Rosie's secretarial skills - even in the company of chum Penny Green? Is there not a danger that the sophisticated world of modern marketing techniques will confuse a girl struggling to get her typing speeds into double figures? Exposed to the attentions of such as smooth Robin Matlock, artist Blake Edwards, dynamic Wolfgang Bang and Rex the Wonder Dog, will Rosie be able to preserve her moral standards at the level readers have come to expect?
