This idea is under discussion with an interested writer.
The Russians want a deal to supply gas to the United Kingdom at favourable prices.
They know that the senior British official in the Department of Energy, Drew Bullivant, has a secret flaw: he's a violent sado-masochist, a sadist who narrowly escaped jail for mistreating a woman some years ago when she refused to testify against him despite being tortured by him.
Alex Makolov is a Russian businessman, now resident in the UK, seemingly at odds with the current regime, but actually a spy on their behalf. He too is a sado-masochist, though of a kindlier sort. He resolves, under instructions from his masters, to recruit a woman who will seduce Drew by submitting to him.
Who will she be? You tell me: all limits respected. She needs to be a woman played by a woman, sorry, that's just my preference. She needs to be handsome, devious and to get profound pleasure from sexual torture and secret humiliation.
I would play both Drew and Alex.
