BBC Sherlock Holmes and the Nightshot Experiment (COMPLETE)

"The universe is rarely lazy enough to deliver a coincidence, especially one in plain sight. When something is so eager to be spotted then it would hardly be polite to ignore it"
Something ghastly is occurring in the shadows of London. Three people have died and the cause of their death is unrecognizable, the only link found is a series of threatening letters sent directly to each of the diseased. With Mycroft stumped and the British Government in peril it's up to the consulting detective and his blogger to solve the case before time runs out.
With the murderers motives and methods opaque Sherlock finds himself rapped up in a mystery that is not only perplexing but emotional in a way that he could never have imagined.
Will the team solve their most personal case to date?
Or will they too fall victim to the illustrious Nightshot Experiment?
THE GAME IS ON!
(Contains mild Adlock)
