Where to find the key to Iris Constance's chest

From the house where you found the chest, return along the road to the southeast until you see a wooden cart near a large tree. Turn down to the right, follow the entrance between the stones on the left, leading to the river. Approach the river and turn left and jump over the fallen tree, then jump over to the other side of the bank. Go right and get to the other side of the bank. There is an entrance through the stones on the left, but you don't need to go there.

Continue left and jump over the stone wall to reach a hidden area beyond. There is a corpse here. Examine it and take the key. Open the chest and take the new rifle.
