Grandchester Mystery Mansion

Grandchester Mystery Mansion is a haunted house exhibition in Nuka-World in 2287

Background
Presumably here, Lucy Grandchester became possessed and murdered her parents, then committed suicide by hanging shortly after her 18th birthday. Currently, the house is quite booby trapped and is being used by Zachariah.

Layout
The house is locked, but entry can be obtained from the protectron ticket taker working just outside the front entrance. The player can either buy a ticket, pick a ticket up off the ground by the protectron's feet and present it to the protectron, pass a Speech check to convince the protectron that they're an employee, pickpocket the key off the protectron or destroy it and loot its corpse.

This large building features several accessible floors. The tour of the building is linear, often locking the player in until the automated announcer finishes describing the current room and asks the player to "please proceed to the next room". The tour moves through the main floor, right until the kitchen. In the kitchen is a master locked door that leads to the basement. Inside the basement is a novice locked door with a bloody scene containing six trader corpses.

From the main hall and from the kitchen are three stairs going to the second floor. The doors on the second floor accessible from the main room are all locked and need a key (and are opened later as part of the tour). The door accessible through the kitchen is unlocked as it is part of the tour. The hallway upstairs is protected by an automatic turret.

The second floor has several chambers, the first one is rigged with gas and was used for seances. The gas can be turned of by using the terminal in the back left corner. The next hallway ends with dead end stairs, and the bedroom of the child on the left. Adjacent to the child's bedroom lies the parents' bedroom, currently in use by Zachariah. In this room is a master locked door that leads to the attic, along with a locked exit to the building.

The attic contains both weapons and chemistry workbenches, along with a large amount of junk.

Notable loot

 * Grandchester Mansion key - looted of the ticket taker.
 * SCAV! Issue #4 (+5% explosives damage). On a wooden box in the attic storage/workshop.
 * Nuka-Punch recipe book in the room with Zachariah.
 * A Protectron model in the basement, behind a master locked door. After entering the room, it stands on the right on a tool board.
 * A mini nuke in the attic, just behind the steamer trunk.

Appearances
Grandchester Mystery Mansion appears only in the Fallout 4 add-on Nuka-World.

Behind the scenes
The Grandchester Mystery Mansion is most likely based on the Winchester Mystery House, due to its similarity in name and history with supposed hauntings, seances and strange architecture meant to confuse spirits, such as doors and stairs to nowhere, windows overlooking other rooms, etc. The external appearance of the house and entry sign are almost identical to those of the Winchester mansion.

Bugs
A glitch may also happen when you wander into the room with the fire traps and the door behind the Gunner Major Gutsy will be open and you cannot enter the room without the Grandchester Mansion key.
