Grandchester Mystery Mansion

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

Background
This mansion was the family home of the Grandchester family, Hannibal, Morticia and their daughter, Lucy. Lucy Grandchester allegedly became possessed and murdered her parents, was committed to a mental institution, then escaped and committed suicide by hanging in the attic shortly after her 18th birthday. An indeterminate time later, this house was converted to a tourist attraction, taking advantage of the high traffic from the nearby Nuka-World amusement park.

Currently, the house is booby trapped and is being used by Zachariah, an ex-Gunner from the Mass Pike Interchange.

Layout
The house is locked, but entry can be obtained from the protectron ticket taker working just outside the front entrance. The Sole Survivor 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 are 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 Sole Survivor in until the automated announcer finishes describing the current room and asks them 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 automated turret.

The second floor has several chambers, the first one is rigged with gas and was used for seances. The gas can be turned off 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 a weapons workbench and chemistry station, along with a large amount of junk.

Notable loot

 * Grandchester Mansion tickets - Sold by the ticket taker protectron at the entrance of the mansion.
 * Grandchester Mansion key - One in possession of the ticket taker and another held by Zachariah.
 * Nuka-Punch recipe - In the room with Zachariah.
 * SCAV! issue #4 - Nuka Brahmin Stampede - On a wooden box in the attic, on the right hand side directly after entering the room.

Appearances

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.
 * The Grandchester Mystery Mansion may also be based on the Lizzie Borden House located in Fall River, Massachusetts where a young woman named Lizzie Borden allegedly murdered her parents with an axe in 1892. She was later acquitted after a much publicized trial and the house today is considered one of the most haunted locations within the state. Some theories also claim the reason why Lizzie committed the murders was due to demonic possession.
 * The style of narration is similar to that of the Ghost Host heard in the Disney Haunted Mansion attraction.

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.
