Aftertaste

You enter a cafe, and the scent of coffee fills your nose. You think about what you're going to order, as one does in a cafe, when you realize, perhaps a little too calmly, you have absolutely no memory of who you are. No name. No job. No home. No identity. But that's not important right now: Hot guy alert! You meet Yonah, another patron of the cafe who is a mystery and horror novelist; he tells you that you are a detective, and a rather good one, at that. Using your deductive reasoning skills, you have no choice but to learn about who you are...and who Yonah is, too.
