Ace, King, Queen and Joker

I won an interesting quiz or a lucky draw I do not know. But the interesting thing is that I participated in a competition organised by Delhi Book Club on their Facebook page in which one has to suggest the name of the authors as Ace, King, Queen and Joker of the pack. According to me it was like this -

ACE - RAVINDRANATH TAGORE
KING - W. SOMERSET MAUGHAM
QUEEN - PEARL S. BUCK
JOKER - CHETAN BHAGAT

And according to you who out of numerous authors you have read is Ace, King, Queen and Joker of the pack?
