It takes about a minute to disable the locks on the three doors, and sneaking a peek beyond, he'd find that one door leads into a prison, and the other opens into a wine cellar. Listening carefully, he'd hear the sounds of someone in the prison, but didn't have an angle to see more, without opening the door. The trapdoor leads into a small room that appears empty - though two more secret doors, visible from this side, and a trapdoor leading up, are all present. These doors are not locked - and the trap door lead up into an identical room on the floor above it... and a<em>third,</em>identical room, on the floor above it.
