Nikola Tesla said to think of the Universe in terms of energy, frequency and vibration, and with mankind standing at the dawn of a Type 2 civilization, the Master of Deduction is tempted into the case of his life; one that will pit his wits against the enigmatic Dorian, a celestial messenger bursting with equal amounts of good and evil and will uncover our secret history and lift the lid on the unforgivable crimes of the elite. The human race is about to be wiped out in a game that has no right or wrong answers, only choices made and the bodies are starting to pile up. This time however deduction won't be enough and Sherlock realises that going deep inside his soul is really the only way out.
