Inquisitor's note

The Inquisitor’s note lies on a table in the dungeon where the game begins. It is the way out: after the blocked passage, the next door needs a key, and the note says where the Inquisitor hid his spare one, in a stash in the wall together with a King’s signet and an Inquisitor’s medallion.

Use it from your inventory to read it again; reading does not use it up.
