Scarlett has discovered your fiddling the expenses. Little does she know that you're authorised to do exactly that- all of the company's secret black research projects for the security services come under your department, and fiddled expenses is how the company conceals what the government want concealed. She threatens to take this to the board - and while that would cause you no problems, it would raise a stink in terms of minuted comments and matters for public disclosure.

Only one thing for it - this redhead busybody has to be dissuaded from blowing the whistle!
