Mulholland Books. (Read their mission statement here). Some of the authors signed to the imprint are Mark Billingham, Lawrence Block, Marcia Clark, and Duane Swierczynski.
Recently, they put up a great new website featuring some cool articles by their authors and other "names" in the crime/suspense genre. They recently posted an interview and a live chat with Don Winslow, author of The Dawn Patrol and other novels.
Check out what Hard Case Crime's Charles Ardai has to say about noir.
The website is a great start and I look forward to reading the books they publish.
