I’ve gone about things a bit backwards, because I only read Brisk Money after already having read Made to Kill (and Standard Hollywood Depravity, too). So the twist in this tale was one I already knew. It’s still a fun short story; good set up for the later stories, and a good pastiche of Chandler’s general style — if not quite his flair at coining a phrase. It doesn’t take itself too seriously: honestly, all through it you can feel that the author is having fun. It’s Chandler-esque sci-fi, where Chandler called sci-fi fiction crap, and Christopher takes obvious joy in using the noir setting and bending it to take account of a robot detective.
I can’t promise it’ll blow your mind, but if a noir detective robot story appeals, then I can pretty much guarantee you’re going to have fun. It’s well-structured, too, which is also a delight to me in a short story.
