I'm a librarian who loves anime, manga, and reading a wide variety of genres.
No one's been murdered yet, but we do have some mysterious kittens dropped off by someone the main character, Charlie, thinks is probably a frightened child, and a new neighbor who insists that she has a long history in the area but who no one seems to know anything about or even fully remember (one person thinks she looks somewhat familiar, but that's it). There have been several scenes of Diesel acting as the kittens' adorable babysitter, letting Charlie know when the tiny idiots were doing something that might get them hurt.
