I never talk about books in progress. I could decide to change it to a series of seafood recipes, after all.
I had been obsessed with the Arthurian legends all my life, and I knew that that would work its way into any trilogy I wrote. I was fascinated by the Eddas, the Norse and Icelandic legends, Odin on the world tree.
I'm happier not pretending I know anything about El Cid in Spain. He's a Spanish national hero. I'd rather invent a character inspired by him but clearly not identical to him. And then I feel liberated creatively.
When I was 18 years old, in a more innocent time, my first backpacking trip through Europe, I sneaked into the Temple of Saturn in the Roman Forum after nightfall and spent several hours in there avoiding the guards patrolling.
I don't plan ahead; each book finds me. History itself, the resonance of the past with the present, is the common denominator in all of them.
The poems were the only thing I wrote that was not for everyone else. Then my editors at Penguin, who were also friends and had seen several of them, aggressively urged me to do a book. Editors can be aggressive, especially after drinks. That's how 'Beyond This Dark House' appeared.
There's a level at which, if you take poetry seriously, the focus it involves... that never goes away.
