John and Sherlock become the bestest of friends, and maybe lovers, too, with the help of their daemons. Mild slash. Johnlock. His Dark Materials AU (basically Sherlock and John, but more adorable and with daemons)

Sherlock and John get a new flatmate. Meanwhile, Sir Charles Latrom has stolen Lyra's Alethiometer. Will and Lyra can't go on without it. The only person that can help them is a currently bored and sulking sociopath genius. Can anyone guess who that might be? No pairings.

Labeled a freak, he doesn't mind so much when he finds work as a consulting detective, but will his daemon ever appear like it has for all over visitors?
