With your master taking care of her, climb onto the tree marked on the map and wait for the poachers to appear. You need to kill them, at best with the rope dart.
Quickly jump onto a branch above the first enemy, aim at him and hold down the attack button. the target will be strangled to death.
Kill the second enemy using the same method, but this time lean the analog stick towards yourself and Connor will jump down to the ground, hanging the enemy on the branch.
The third enemy needs to be approached from behind. As you get near, aim at him and keep holding down the shoot button until Connor kills the poacher with a hidden blade.
After his death, two more enemies will appear. Quickly turn around 180 degrees and run onto the leaned tree. From above, you will be able to strangle the man below without alarming his friend.
With both of them dead, run to the designated spot and watch a short animation. Afterwards you will only have to return to Achilles to end the mission.
Speak with Myriam and head to the circle marked on the map to find traces of a wild cat. They will be marked with a magnifying glass icon.
After finding the third trace, the beast will appear. Follow it by running onto the fallen tree and afterwards jump down from the rock.
Beside the mine entrance you will find Norris, who will tell you that the car has hidden underground.
Enter the cave and press the interaction button when prompted. Soon afterwards Myriam will make a shot which will end the mission.
Fool Me Once...
Meet with Norris and afterwards head to Myriam with him.
After a short conversation you will have to kill three wolves marked on the map. You can do it by pressing the buttons which appear on the screen.
With the beasts dead, climb onto the marked hunting blind and run to the attacked girl by jumping between branches.
Your target is the poacher. Catch up with him and kill him to end the mission.
