For those of you that like SF and those of you that like Raymond Chandler style mysteries, I would heartily recommend This Book: Down these Dark Spaceways
It is a collection of 4 or 5 novellas and all are quite good. They are hard-boiled-detective novellas set in SF environs. I find myself hoping the editors come out with another volume. Best part it, they're all cheap as can be as you'd be buying them used. They start at $0.75! Even for someone in say, Trinidad, that's only around $4.50TT!
