It was all in the orchestration, he claimed: in knowing how and where to pitch each and every particular argument; who to intimidate; who to trust, who to flatter and court; who to challenge; when to underplay and exactly when to let out all the stops.”

Where now this night is day,
And even through faith of still averted feet,
Making full circle of our banishment,
Amazed meet;”
—Coventry Kersey Dighton Patmore (1823–1896)
