Zane house

 is one of the buildings in Minefield - the others are: Benson House; Gibson House and Gillian House.

The door to the house can be opened with the Ridgefield Gate Key carried by Arkansas, the sniper located in the destroyed building in Minefield. If you've enslaved him or don't have the key for other reasons, you can pick the Average Lock (level 50 Lockpick required).

Notable loot
In the Lounge:
 * Pre-War Book

In the "Locked: Easy" safe behind the cabinet in the Study:
 * Stealth Boy (possibly)

In the second bedroom:
 * Pugilism Illustrated
 * Teddy Bear: this one is visibly larger than the other bears in the game. It will stay that way after taking it and putting it back once, but if you pick it up and drop it again it will become normal size.

Appearance
only appears in Fallout 3.
