Go left to until you reach a cemetery. Take the Rose Heights Cemetery Map from the bench.
This cemetery isn't really that big. In fact there are only few important places marked on your map. The first one is East Garden.
You should notice a man digging a hole and a big crack in the ground. Prepare a knife and climb down. If fighting isn't your forte, you can always return to the Town Hall to save your game. In any case climb down to fight Ferals - your new enemies. Kill them with a fast knife combo.
Xbox 360: killing a first Feral will give you Eddie's Legacy achievement (10 p.)
Move around - there is a Old Strone Plate on the fountain. Take it, go to the southern part of the crack, and climb up. Take the Health Drink.
Go west toward the row of crypts.
You're in the part marked as a Family Crypts North. Go west and behind the first gate you should notice a save point. Go west till the end of the road, turn left and squeeze through the crack.
Now you're in the Family Crypts Mid area.
Go east until you reach a closed gate. There is a Health Drink on the left and hole on the right. Duck under the wall and go east to find another closed gate. Turn left and squeeze through a crack.
A dog will attack you, so prepare your weapon. The knife is the best choice. Go south and turn left (east) and jump to the hole. Go through the window and climb up.
There is a dog in the middle of this garden (it's eating a body) so be careful. Go north and turn east. In the corner you should find a Health Drink.
Go downstairs - you don't need to fight this dog, you can simply go north toward West Garden.
Go upstairs and towards the fountain. Take the Strange Stone Plate from the fountain.
Use both parts of the Plate on the gate at the northern part of the garden.
Go north and turn right at the parking lot.
