It has been two years since John's marriage had fallen apart and he had moved back to Baker Street. Things between him and Sherlock are still very much undefined, and John is certain that he'll have plenty of time to figure it all out. This notion proves dangerously false: strange things are set in motion when Sherlock's long-lost “acquaintance” from university appears on their doorstep and a baffling burglary case frustrates Sherlock to no end. What is behind Sherlock's black moods and dwindling health? Where is Mycroft? Why would someone steal artefacts from the British Museum that have interested nary a soul for decades?In the midst of this thickening fog stands John, who will soon have to take on an enemy much greater than even Moriarty.
This fic excels at plot, giving us a mystery that twists us in circles and a slowburn romance woven into it all. It does a great job working in Sherlock's past, both academic and romantic, and letting us know the enigmatic man in a deeper way.
