If the perp/hf is in a house, the slice will point towards the door of that house. If the perp's hf is on another layer (cave, mining layer 2, 3 ...) the slice will point towards the same location (with the same coordinates) but on the floor you are.
So for example if you track and you find an empty spot where the slice points at, you should be able to find the hf when you build one or multiple mine holes here. (but it's best to just find a cave/minehole nearby)
