Sherlock Holmes story where after Holmes shows up, the perp starts actively starting to mess with the case to make it harder than it was already. Holmes catches them anyway, of course; at the end, they're like "yeah, I knew you were gonna catch me anyway, cuz I mean you're Sherlock Holmes, right? I was so scared I thought about just turning myself in right away, but then I decided that instead I was gonna make things more interesting for you instead" and Holmes is like "lmao no, yeah that was the most fun I've had in years. Still murder, tho"
