I've tried, in 'Bloodmoney,' to tell a story that gets at the crazy relationship between the ISI and the CIA, these absolutely fascinating, often mutually destructive two scorpions in a bottle kind of relationship that they have.

I began writing fiction because it was the only way to tell all the intricacies of a real-life spy story.

The relationship between a Russian and a bottle of vodka is almost mystical.

If you walk into the front hallway of the CIA, you will see, on your left, a statue of William 'Wild Bill' Donovan. Bill Donovan was the person who created the OSS, the Office of Strategic Services, which was America's spy agency during World War II and then kind of morphed into what's now the CIA.

CIA officers aren't idiots. They knew they were heading into deep water - legally and morally - when they signed up for the interrogation program. That's part of the agency's ethos - doing the hard jobs that other departments prudently avoid.

We're used to scorpions, black widows and rattlesnakes, ... Now we'll just get used to different wildlife.
