It was necessary that I should return without delay to Geneva, there to watch over the lives of those I so fondly loved and to lie in wait
for the murderer, that if any chance led me to the place of his concealment, or if he dared again to blast me by his presence, I might, with unfailing aim, put an end to the existence of the monstrous image which I had endued with the mockery of a soul still more monstrous.
The Cadmeans were incensed at his success, and set a force of fifty youths with two captains--the godlike hero Maeon, son of Haemon, and Polyphontes, son of Autophonus--at their head, to lie in wait
for him on his return journey; but Tydeus slew every man of them, save only Maeon, whom he let go in obedience to heaven's omens.
To lie in wait
for me now would mean that the creature had appreciated what had happened to me, and this in turn would argue some power connecting cause and effect.
