(Set after aGoS, the film universe.)

Everyone thought that after Moriarty there would be a somewhat resemblance to a calmer life in London, that there would at least be a breather before Sherlock sunk his teeth into another mission.

But dangerous things are happening.

New roads paved are turning into sinkholes and new bridges are constructed at the same speed they are falling apart, killing more people each time.

Is it just engineering failures or is there something larger here at play? Something linked to the deceased Moriarty even?

It's time for another mission, this time with the addition of the new roommate Sherlock has lodging out Watson's room. A roommate who cross-dresses more than Holmes himself.

(I only own my OC and the storyline.)
