After dinner, he confronts von Till about his involvement with the attack on the airfield and while von Till admits nothing he forces Pitt to leave the villa at gunpoint through a door that leads him into what is known as the Pit of Hades. It is later explained that the Pit of Hades is a labyrinth once used in ancient Greek times when the villagers sentenced a convicted felon to death. The person sentenced to die was given the choice of an instant death or choosing the Pit of Hades. The labyrinth had only one entrance, a concealed exit, and roaming amongst the many passages was a hungry lion. In recorded history no one had successfully found the exit before the lion found them. While von Till does not have a lion he does have a very large white German Shepherd with which Dirk Pitt engages in a mortal struggle.
