Oh, do give us a break. You were the one who invoked Holmes. That sets an expectation of performance.
Now, back up how this happens. How is it that this Int 5 character (-3 ability modifier to Investigation skill) is far superior in Investigation to Watson, Lestrade, and indeed the entire London Police force (which, as a large law-enforcement, should be expected to have several high-Int officers proficient in the skill among them). How is the iconic mastermind Moriarty under any threat of Holmes finding out what's going on.
Why is it that people are engaging Holmes, and not Mrs. Hudson?
Does figuring out what's going on require an Intelligence (Investigation) check? Could not savvy players put together the clues themselves to solve the mystery?
There's also a whole thread on this topic you're free to read. It was linked upthread and inspired by a thread prior to that. It needn't be rehashed here. So there's the break you impertinently demanded, moderator.
