Exploring the Boyle Estate garden | Mission 5 - Lady Boyle's Last Party Dishonored Guide
Last update: 11 May 2016
New Main Quest: Identify which costume your target is wearing
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.
I recommend that you start by examining the enemy's outpost located near the main entrance to the Estate (the guest entrance). The location is locked off by default, but the guards watching over it, have gate house keys on them so you can steal it from one of them.
After you unlock access to the outpost, try and eliminate the guards inside quietly without raising alarm and letting the guests realize what is going on. After you do that, explore the entire room to find gold, food, Sokolov's health elixir, a book and a blueprint.
New Optional Quest: Follow Lord Shaw
In the Estates garden, you will find Lord Shaw, i.e. the person you were asked to meet by Lord Pendelton on your last visit to the pub. It is of course worthwhile to initiate a conversation with him in order to give him the note. The aristocrat will ask you to follow him into another place.
After you reach another part of the garden, it will turn out that you will have to fight a duel of honor on Lord Pendelton's behalf. Approach the box and collect one of the pistols. Note - If you do not want your statistics at the end of the mission to go worse, you need to ignore the duel, because the only way to win it is by shooting Shaw.
New Optional Quest: Return to the Hound Pits Pub
Position yourself back to back with Shaw on the plate, and wait for one of the gathered NPC to start the countdown. As soon as you hear "one", you need to turn around as quickly as you can and shoot Shaw. What is interesting, you can use the slow time/hold time power right before you turn around, which will make the duel easier for you to fight. After you shoot Shaw, run through his pockets to find gold.
Resume the exploration of the area adjacent to the Boyle Estate. I recommend that you explore the guard quarters (i.e. the building that you might have started your exploration of this area. Inside, there are gold, food, a guard quarters key, pistol ammo and a rewire tool.
