What is the quote about planting the knife in the first act which you will use in the third?
It’s something relating to Shakespeare and drama… I believe it’s somewhere along the lines of “plant the knife in the first act, which you will use in the third,” but that’s not quite right.
Please help me out! What is the exact quote and who said it?
It sounds like you are thinking of the quote by another playwright, Anton Chekhov:
If in the first act you have hung a pistol on the wall, then in the following one it should be fired. Otherwise don’t put it there.
