The Maroon Assassin
Meet Anto at the Assassin Bureau in Kingston to start this memory. Your mission is to eavesdrop on multiple targets without being spotted. Though this may sound like a bit of trouble, Kingston is happy to provide multiple Dancers near the eavesdrop locations to conceal Edwards from suspicion, so make sure you hire some. When the men begin to run, follow the one through the alley to your right and tackle him to complete the memory.
Recruiting Maroons
Talk to Anto in the west section of Kingston to continue to the next memory. You need to tree three slaves held at gunpoint in small Restricted Zones, hopefully quietly, with Anto's help.
Your first target is a short walk west, but rather than heading through the front gate guarded by enemies, head along the north side to a small house that gives you a perfect double air assassination on the guards below.
The next slave is to the northeast, conveniently near some dancers that can be used to distract the guards by the prisoner and allow you to easily release him.
The final slave is to the northeast and you can enter by jumping the fence by some crates when the guard isn't looking ans whistle him over for a corner assassinate. Anto will take out the other guard and then you need only worry about the final guard protecting the slave to complete the memory.
Under Attack
Return to the Assassin Bureau in to start this memory that is similar to the Dinsmore one, with multiple waves attacking the Bureau. Your objective is to keep Anto alive, so stay close to him and use kill streaks to deal with the weak soldiers. In between waves you have the opportunity to thin the next way by going out and striking them down, but make sure you return to the Bureau when they begin to attack. Once you have survived three waves you will complete the memory.
The Commander's Ruse
Talk to Anto in the center of Kingston to start this memory and then use Eagle Vision to locate your target. You can simply follow Anto, who not only knows the way but will also deal with any Marksmen in the way, to reach the Restricted Zone.
Rather than heading in through the obvious south side of the zone, circle around the east side to the northern entrance to spot the Captain with Eagle Vision. Once you have him in your sights you can use a Berserk Dart on the Captain or the nearby guards to have him killed and complete the memory.
