Amanda Curzon is an entertainer.
That is what she claims and it is supposedly how she earns a living but there are few places where her name would have ever graced a marquee so the description is open to argument.
What she is mostly is a sex-crazed adventurer who seems to be totally under the control of her highly dominating travelling companion, Oscar Sallis, a wrestler by trade. He rules virtually her entire world except for the fact that since she is a whole lot smarter than Sallis (and who isn't, apparently), she knows when to say yes to his sexual demands and that gives her a whole lot of control since Sallis is even more sex-driven than Curzon.
Curzon hails from the Cockney area of East London. How she got to be from there to the region in and round the Iron Curtain is mostly a mystery and largely unimportant though it almost certainly is because that is where Sallis felt he could earn a living wrestling there and where Sallis went, Curzon followed. Except when they fought which seemed a frequent occasion.
It is very important to note that neither of these people are trained agents and it is absolutely clear that no government agency would ever willingly use them. Nevertheless, whether from gullibility or a love of thrills bordering on insane, they both get involved with different spy organizations and manage to just barely escape death on numerous occasions. 'Barely' is particularly appropriate for Curzon because regardless of what she is doing or what is going on around her, there is good chance she will find a reason to undress.
