AnaWritesRandom got it, the answer was "Ship in a Bottle" by Fin!

Difficulty: Hard

(And because it's harder I gave more lyrics)

We are friends are we not?

And our interests are the same

We collaborate

And trust in fate to parcel out the blame

There are ends we've all got

That can justify the means

We negotiate

Then fabricate the facts behind the scenes

Keeping all the details vague

And secrets hidden

Safe on the balanced sheet of those you trust

:)
