skyfyre has posted her very first fanfic and let's give her encouragement to write more. This Sherlock Holmes story set in the new Sherlock series' continuity* nails the characters and is both touching and silly fun.
There is a passing bit of slash so if you'd prefer your Holmes/Watson platonic then you might want to give it a miss but it would be your loss.
*Set in the 21st century.
Edited for those like Feni who haven't heard of Sherlock.
