I've finished reading the collection of short stories by Anthony Boucher. While I was aware that he wrote in the Science Fiction/Fantasy and Detective/Mystery genres, I didn't realize that he did both at the same time. There's a story about a werewolf...who gets mixed up with spies. And the solution to a detective's case?...time travel. They are all really excellent and clever stories. In addition, every single one of the main characters is a serious drunk. Like blacking out for 36 hours, or when waking up from being punched out, naturally assuming that he'd just been drunk. Highly recommended.
