I agree entirely with Whirlybird when it comes to "Talk Down", I still have my (battered) copy and re-read it every now and then, a great yarn. You're not the only one, Whirly: what a wimpy "heroine" indeed, and what about her Hooray Henry boyfriend?
ISBN 0 340 23675 2 in case it helps, although as already mentioned it's easy to find via Internet.
