Best books on or by.....

Winston Churchill. I realized today that I am very poorly read on Winnie. Ideas?

Winston Churchill's books are great literature, especially his Marlborough books, but also his history of WWII and his History of the English Speaking Peoples. Best books _about_ Winston Churchill? That's hard to say, but Martin Gilbert's abridged biography of him is quite good.

I just ordered a bunch of books on him for my boss last year.. amazon.eu certainly has a better selection.
