>Follow the lady.
>You follow the woman as she leads you back towards the kitchen and then takes a different turn ending in a heavy wooden door. She produces a small key from her pocket and opens it, then leads you down a rather extended series of cramped stairs, doubling back on each other several times as they descend deeper. The air cools noticeably as you proceed. Eventually you arrive in the wine cellar.
>It is a very neatly arranged space, though the construction is rudimentary and coarse, with little more than packed earth and support beams for walls. A couple of lanterns hang from the ceiling beams, shedding soft light on the space. Within it are several filled wine racks, along with a multitude of wooden crates and barrels, both large and small. Several large sacks are piled against one corner of the room.
>"It was right here," she says, gesturing towards the top of a small stack of crates. "And then the other day it wasn't."
>Do we know how difficult it is to duplicate a key based on memory?
>Constructing an functional reproduction of a key based only on memory of having handled it would be essentially out of the question, as far as you understand things. Unless the lock was extremely crude, but this one did not appear to be so. Perhaps if one had taken precise and detailed measurements beforehand, but even that would require a high degree of skill.
