Noirish night

I spent a very pleasant evening with Glenn from International Noir yesterday evening. We hooked up at Kramer's bookstore off Dupont Circle in Washington DC. Had a good browse of the books and chatted about different authors and books and other stuff. I did quite well in that I only came away with 6 books. Afterwards I headed to a big book-barn place by myself. It was a strangely lifeless, soulless space. It had 7 bookcases of SF, 9 cases of romance and 3 of what it called mystery, 90% of which were cozies. I couldn't get my head into alignment with its stocking policy and left after five minutes (and I'm usually a minimum of a good half an hour browsing kind of a person). Also spent a couple of interesting hours in the Smithsonian Air and Space museum; well worth a visit if your visiting DC.

Washington DC recommendations?

This time next week I'll be sitting on a plane winging my way to Washington DC for a week at a conference. I have a short list of fiction I intend to pick up whilst I'm there that I can't purchase here yet, but what I'm after right now are some recommendations for some DC crime fiction. I have 'A Firing Offense' by George P Pelecanos for the plane, but what other books should I keep an eye out for? All suggestions gratefully received.
