What I discovered is I don't like to repeat lead characters because one of the most pleasurable things in a book to me is learning about the lead.

For something that's supposed to be secret, there is a lot of intelligence history. Every time I read one book, two more are published.

In the 1930s, there were so many different conflicts going on between the British, the French, the Russians, the Germans, the Spaniards, the Romanians and so on.

I don't just want my books to be about the '30s and '40s. I want them to read as if they had been written then. I think of them as '40s novels, written in the conservative narrative past.

No one can take Jesus away from me. There's no doubt there was a historical figure of tremendous importance, with enormous notions. Such as peace.

Nothing has come from this whole 'peace industry' except for conferences in five-star hotels and a waste of money.

My different personalities leave me in peace now.

Although the war in which you fought took place more than half-a-century ago, your courage, your sacrifice and your patriotism reaches through the decades and inspires us today.
