You’re the new employee at St Bartholomew’s Hospital in London. You were only hired two weeks ago and are to be a mortuary technician there, though of course being new you are still finding the ropes of the job. Because of this the hospital has paired you with a senior technician, Carla Valentine, who is tasked with showing you what to do. In spite of this Carla likes to tell you what to do rather than show you.

Today Carla has asked you to help Molly Hooper. No, she did not specify with what. She only said to come back and see her at 6:30. You walk down to the morgue and push open the cold metal door expecting to see Molly there only you are met with the sight of a certain famous consulting detective poking around a dead body on the examination table instead. He turns around to face you, eyebrows furrowed.
