 They also discover that Cameron himself had been aboard the ship, hidden in the area between the inner and outer hulls; he had unexpectedly jumped ship, however, during one of the fuel stops.The "Icarus" successfully evades an attack off the planet Utheno, and McKell decides to make a break for Earth, outrunning the Patth by using the alien stardrive.This requires dismantling a good deal of the ship; while exploring deep inside the "Icarus"' interior, McKell discovers by accident that the "Icarus" is not a stardrive at all; it is actually a stargate (a hitherto-theoretical interstellar-teleportation device), and Arno Cameron, instead of jumping ship as they had supposed, had instead been temporarily stuck at the stargate's other end.
