Exploring the basement and the ground floor of the Estate | Mission 5 - Lady Boyle's Last Party Dishonored Guide

New Optional Quest: Gather information by talking with guests
New Optional Quest: Sneak upstairs and search the three bedrooms for clues
Note- the [Boyle Estate] is a place where all of the characters are neutral towards you. That is why I recommend that you keep your weaponry sheathed/holstered (pressing and holding down the "F" key). Try and do not rob people that are within the sight of the other people, or else you may start an alarm after several attempts. You can eliminate the problem by waiting for an individual NPC go to an area that is not being watched, or by using a power (Possession of time hold etc.). It's worth noting here that the abovementioned restriction does not hold for items that you can find in the building. In this case you do not need to worry about negative reactions from guests and hosts alike.
It is best to start the exploration of the Boyle Estate from the foyer (main entrance). You can here have a look at the Boyle Party Guest Ledger, and even add your name to it, although this will give you nothing. It is a good idea to deal with the newly-unlocked optional quest and start a conversation with a nearby group of guests. In the latter case, it's worth knowing that it does not have to be anyone in particular. You can even talk to an anonymous NPC without any specific name.
From the guests, as well as from your own observation, you will learn that in the Estate there are three ladies of the name of Boyle - wearing white, red and black clothes. Nobody knows which one is whoch and we will later on deal with determining their personals. Meanwhile, you can of course talk to each one of the three ladies, but it's optional. Continue your exploration of the ground floor and remember about the possibility of collecting valuables, gold, food and books. The same freedom of action does not concern the abovementioned gold pouches. If you are caught red-handed once too many, you will have to deal with guards.
New Optional Quest: Get Miss White a drink
It's a good idea to eavesdrop on the conversation Miss White with Ramsey are having. Soon after the conversation ends, you should receive a quest connected with the lady. Go to the ballroom and prepare a drink by interacting with the fountain (the above screenshot). Return to miss White with the drink, and you will learn that Waverly Boyle ma is wearing white clothes, and Lydia Boyle - red ones.
After you have sufficiently explored the ground floor, find the staircase for servants that is located near the ballroom. Use the stairs to reach the kitchen area in the basement. Look around the place for gold, food, a book, Sokolov's health elixir and a Piero's spiritual remedy. It's worth adding that, although it's only service that's remaining in the kitchen area, you won't be chased away by anybody.
In the basement proper, you can only find gold and Sokolov's health elixir, but watch out for rats that may attack you out of a sudden. The most important place in the basement is the family vault, and you can access it in two ways. It's way easier to pass through the ventilation shaft as a rat, but you can also steal the basement vault key if your Possession power is not developed. The key can be stolen from Lydia Boyle's bedroom on the first floor. Inside the vault there is a considerable loot, like gold (including as many as five bars!), Sokolov's health elixir, Piero's spiritual remedy and a rune.
