The characteristic of a Secret Agent is that she primarily lives a perfectly decent and moderate life. If you'd be to observe her in daily life, the last thing you would expect from her is having a side job as a high class es**rt companion. Not because she doesn't have what it takes, but because she simply doesn't appear to be 'the type. And that's a good thing. You see - these high class courtesa
ns have too much to lose in terms of their primary careers and / or in private if their naughty side job would ever were to be exposed. On the other hand, that's exactly the kick they get out of it: a naughty, luxurious and perhaps even slightly controversial double life in the most enticing sense of the word. Their adventures will forever remain between themselves and their agency. Forever Top Secret, as is the case with an undercover agent.. And thus: Secret Agents.
