I probably should have read this before writing Twisted 50s campaign frame for Mortal Coil because it would have given me more ways to present and slice up the Noir setting. Much of what I wrote falls into Horsley's 20-45 range but I've included some of everything else, without necessarily giving such a tight historical perspective. But then the Mortal Coil campaign frame only costs $2.
I've also been reading London Books excellent period thrillers including Kersh's Night and The City and They Drive by Night by Curtis (nothing to do with Bogie). These feel surprisingly modern and I'm thinking hard about a 30s gangster Trail scenario.
