All John Watson and Sherlock Holmes wanted was a flatmate. But they ended up with so much more... As John and Sherlock try to deal with their inner conflicts and the aftermath of their 'adventures' with Eurus, fate brings them across an old friend and a new mystery. A man's house is broken into by his dead wife, and the crime sets into motion a series of events that no one - not even Sherlock Holmes - could have anticipated. (Contains Johnlock)
