amulet in the mansion of Stilton (Dishonored 2)

Hi all. In the house of Aramis's Stilton has a black amulet, it's hidden behind the door, which is impossible. Moving into the past, and zaglyanuv in the keyhole can be seen that there is a dead wolfhound, in the present the door is half open and there corpse wasps, but to go places is still not enough. A little to the left there is a table, in the present it's broken and punched a hole in the wall, but the debris of the table to get there, do not give in the past with this table to do anything. Anyone could get this amulet? Thanks in advance.
