After accepting the contract, a skull marker (which indicates our assassination target’s whereabouts) will appear on the map within a rectangular restricted area zone surrounding the small plantation directly to our north.
Make your way over to the restricted zone and climb onto the roof of the house across the street directly south of the plantation. From here, we can look over the plantation’s walls and turn on Eagle Vision to identify our target.
Drop down from the roof and enter the sugarcane fields here. Use whistles to lure the three patrolling guards into the fields and assassinate them one at a time.
Afterwards, go and climb the stone wall to the plantation. Shimmy along until you are in line with your target. When you are ready, quickly leap over the wall and perform a sprint assassination on him to have him die before anyone can see you coming. This will complete the contract.
