A Deadly Performance

A Deadly Performance was a virtual representation of one of Haytham Kenway's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Haytham Kenway attended , a play by in the, which gave him an opportunity to assassinate one of his enemies and steal his amulet.

Dialogue
Haytham entered the Royal Opera House. Haytham briskly handed over his hat, invitation inside, all the while continuing to walk forward. Good evening, sir. This way, please.'' Haytham joined Reginald Birch. Haytham activated Eagle Vision and spotted Miko. Haytham spotted a ladder that led to a ledge he could climb upon. Haytham stood up from his seat and climbed towards the balcony. He eventually ended up behind the theater's stage, which he continued to climb around. Haytham reached Miko's box, after having picked the lock on a door, and sat behind him. Haytham stabbed Miko with his Hidden Blade and pulled the amulet from around his neck, before signalling to Miko's nephew who witnessed the killing to remain quiet. He then left the box and made his way towards the exit of the opera house. However, the murder was soon discovered and people began to panic, to which Haytham soon exited the theater. Haytham met his fellow Templars and showed them the amulet. Haytham left the room.
 * Clerk: Invitation, please. Shall I take your coat sir?
 * Man: ''Ladies and gentlemen, you are requested to kindly find your seats.
 * Reginald: Evening Haytham.
 * Haytham: Reginald.
 * Reginald: I can't tell you how happy I was to hear they'd mounted this revival. Gay's best work by far. Have you seen it before?
 * Haytham: Once. My father brought me here as a child, though I remember little of it. And I don't suppose tonight will afford me the luxury of a proper viewing either.
 * Reginald: No, I'm afraid it won't. On to business then. Do you see him?
 * Haytham: He's seated in one of the boxes above.
 * Reginald: The stairs are watched. You'll need to find another way up.
 * Haytham: I already have.
 * Stagehand: Man the lines! Flats in place! Stand-by!
 * Actor 1: I've got a bit of stage fright!
 * Actor 2: A little dutch courage'll put a bloom in your cheek.
 * Actor 3: Jeremy's really burning up the boards tonight! He's a marvel.
 * Miko: Haytham... You should have come to me. We would have found another way...
 * Haytham: Yes. But then you would have known. For what it's worth, I'm sorry.
 * Miko: As am I.
 * Coach driver: And how was the opera?
 * Haytham: Rather dull, truth be told.
 * Coach driver: Shall we be off, then?
 * Haytham: Aye. To Fleet and Bride.
 * Coach driver: By your command.
 * Reginald: Fascinating... Gentlemen. I hold in my hand a key. And if this book is to be believed, it will open the doors of a storehouse built by Those Who Came Before.
 * Haytham: Ah... Yes, those who ruled, reigned, and then vanished from the world. Do we know what it is that would be held within?
 * Reginald: It could contain certain knowledge. Perhaps a weapon. Or something as yet unknown, unfathomable in its construction and purpose. It could be any of these things. Or none of them. They are still an enigma, these precursors. But of one thing I am certain – whatever waits behind those doors shall prove a great boon to us all.
 * Haytham: Or our enemies. Should they find it first.
 * Reginald: They won't. You've seen to that.
 * Haytham: I assume you know where this storehouse is?
 * Reginald: Ah, mister Harrison.
 * Harrison: Gentlemen.
 * Reginald: How fare your calculations?
 * Harrison: I believe the site lies somewhere within this region.
 * Haytham: That's a lot of ground to cover.
 * Harrison: My apologies. Were that I could be more accurate...
 * Reginald: That's alright. It suffices for a start. And this is why we've called you here, Master Kenway. We'd like for you to travel to America, locate the storehouse, and take possession of its contents.
 * Haytham: I am yours to command. Although a job of this magnitude will require more than just myself.
 * Reginald: Of course. Upon this paper are the names of five men sympathetic to our cause. Each is also uniquely suited to aid you in your endeavor. With them at your side, you will want nothing.
 * Haytham: Well, then I'd best be on my way.
 * Reginald: I knew our faith in you was not misplaced. We've booked you passage to Boston. Your ship leaves at dawn. Go forth, Haytham – and bring honor to us all.

Outcome
The Templars managed to take possession of the amulet, which caused them to begin searching for the storehouse that it matched in America, by sending Haytham to gather together co-conspirators after his arrival in the British American colony of Boston.

Trivia
It is rather improbable for Haytham to climb up to the balcony the way he did, as there are no less than 10 boxes of audiences sitting exactly opposite to where he was climbing, and would certainly have spotted him easily.

If you chose to delay using Eagle Vision to locate your target and let the musical continue on, eventually the dialogue spoken in the musical would repeat. The next part in the musical could only be reached once you have reached certain checkpoints.

If one looks closely, the actors' movements are not in tune with the dialogue, and seem to be a repetition of the same few gestures and poses.
