I just discovered this series. Check it out. Collections of noir short stories, anthologies based in various cities in the US and around the world, Istanbul, Paris, Delhi, London, New York. And on and on. Great idea.
The Boston one, which is edited by Dennis Lehane (he has an entry), has just recently been released. Nearly all of them are available for the kindle, and these seem the perfect books for that device. I downloaded this one today. This Thursday, several of the authors (Russ Aborn, Dana Cameron, Brendan DuBois and Lynne Heitman) will be reading from their stories at Indie Newtonville Books.
