Withheld- (A Sherlock Fan Fiction)

(Plz read the A/N!) The sea crashed against the cliffs like a monster demanding entrance to the one place no one could go. A place that is hidden from the rest of the world. It towered above the island's barren rocky base. Plain and rectangular, no other entrances or exits, just one forbidden door. A single boat approaches, bobbing up and down on the violent waves and dark clouds brew threatening to burst. They say this place is for the freaks and the mental. But anyone who enters will be driven mad by the things they say. By the things he says. This vessel is the only thing that knows the island's whereabouts. It docks and only one man leaves the small transport knowing nothing of the horrors that stir beneath his feet. They sense his presence and go wild, but he cannot hear them. The boat disappears leaving the man on the island.
He is there to do one job.
Keeping only a single person, out of all them, in his cemented prison at the deepest bow of this haunted house of horrors.
As he enters the asylum, the rain begins to fall.

This is a twisted version of the BBC Sherlock sort of...
