Here's the blurb in case you wanted to read it:
Jim Moriarty is on the run from the law while trying to play with Sherlock like how a cat plays with mouse. Except, Sherlock saw him die on top of that building.
John Watson's wife is dead, leaving him with their child and the aftermath for her passing.
Sherlock is solving case after case, but in the back of his mind is an old friend whose suicide still mocks him with that sing song laugh, and it is about to get worse.
When Moriatry steps out of the shadows and back into the spotlight Sherlock and Watson rush to find him before time runs out.
And not only that, but when two new people step into Sherlock and Watson's life, they complicate the already complicated.
