Most Ghosts Are Idiots

The one where Sherlock is already dead but hits it off with John anyway. John returns from Afghanistan later than he did in canon and rents a long vacant flat in Baker Street. But it has a few problems, he discovers, such as the ghost of Sherlock Holmes. Sherlock throws books about, plays the violin at all hours, and leaves ominous messages on the bathroom mirror. John settles in regardless, determined not to let a haunted flat get the best of him. Though he does wish Sherlock would stop hiding his cane. Sherlock’s not an ordinary ghost, but then, most ghosts are idiots.
