What Would A Fic With This Title Be About?

[ECSNorway]

To answer one of my own:

Principia Homicidii: Professor Moriarty spins out a assassination plan that's designed to fail and hand the would be killers to Sherlock Holmes while making it look like the killers were incompetent in following through on his plan. The psychology of these would-be murderers figures heavily in said clever double-cross.

My version of this was a 40k-verse Buddy Cop drama, but, well, that works too.
