One More Miracle

This mainly concerns Mary and John, and is set after Sherlock "dies". It's John coping. However, when one of Moriarty's disenfranchised loose ends decides to kill John, using Mary as leverage, Greg & Mycroft must step in to help. The facts are wrong: John meets Mary a year after this is set - call it artistic license. The story's quite fluffy, with horrific spates of "anti-fluff".
