* NightmareFuel: While plenty of the deaths are violent, with none of the true-to-life [[{{Gorn}} gory details left missing]], the final murder discovered by Holmes is by far the worst. We don't see much of the victim, but whatever Holmes sees, it's enough to send him into a HeroicBSOD.
** It becomes FridgeHorror when Holmes mentions that he has a photographic memory, and you realize that he's going to carry every detail of that crime scene image to his grave.
