Holmes’s Terrible Roommate Habits

While modern adaptations make Holmes look cool and eccentric, book fans online like to compile lists of why he would be an absolute nightmare to live with. According to Watson's journals, Holmes: Kept his cigars inside the coal scuttle, pinned his unanswered letters to the mantelpiece using a massive dagger, kept raw, infected bloodstains on the dining table for "chemical testing", and would randomly wake up at 3:00 AM to play the violin loudly while staring at the ceiling.
