Just finished the new Dan Marlowe bio, "Gunshots In Another Room," by Charles Kelly. It's a great read about the colorful live of the hardboiled author of "The Name of the Game is Death," the Drake series and much more. A good part of the work covers Marlowe's sidekick, Al Nussbaum, a bank robber and successful crime fiction writer himself and their longtime friendship.
Most interesting to people on this site will be the struggles of a man, who lost his wife and did't begin writing until his 40's, to crack the crime fiction market. I don't want to be a spoiler, so I'll just say he had a lot of ups and downs, to say the least, in his quest to make a living as a crime novelist and short story writer. Very inspiring and loaded with lots of unintended tips on how to break into this field yourself.
