This incredible fic deserves WAY more attention than it has gotten so far! It has everything: a good case, our heroes in peril, and all the Johnlock goodness we crave. I absolutely can’t recommend it enough. I am absolutely floored it hasn’t even hit 100 kudos yet (I would give them all myself if I could!)
Go. Read. Now.
