An interesting analysis of the ‘death’ of the mystery genre in the US (and, no doubt, elsewhere).

Amazon, and other ebook sellers, now do a good job of replacing the warehouses full of backlist, and means that once someone discovers your work, they can get their hands on your other stuff easily. This is the basis I’m working on, putting out books and waiting for people to find the one that draws them in. Every so often, I’ll do a stand alone, but I’m going to keep adding to the Rain and Bullets series, and may start others.
