Keeping the Strength to Fight

This is a BBC Sherlock fan-fic, so of course, all rights reserved to the BBC and the producers of the Sherlock series.

Three years after the death of the great Sherlock Holmes, both men are learning to continue along their separate paths- alone.
Still recovering from the loss of his friend, John Watson's life has become a broken record. The same things happening day in, day out. Little did he know that his old life was about to catch up to him, and he would be dragged back into a life of fear, anger and pain.
...And excitement, that too.
However, Sherlock's persistence to destroy Moriarty's name has lead him to a discovery which could put him and his friends in more danger than he thought possible.
Two men, two mysteries. Neither aware of the others trials, but both will co-inside as the truth is revealed, and the challenge really begins.
Though the ever increasing difficulties are piling up, the question is, will they be able to Keep the Strength to Fight?
...Well of course they can, I wouldn't write a book if they couldn't!
Enjoy!
