Agatha Christie said this quote

I will only ask you to believe one thing. I have faith in myself. I believe that I am the man to guide England through the days of crisis that I see coming. If I did not honestly believe that I am needed by my country to steer the ship of state, I would not have done what I have done--made the best of both worlds--saved myself from disaster by a clever trick.''My lord, if you could not make the best of both worlds, you could not be a politician.
