bubble around Triton so that she can escape her confinement in Mlayanu. All goes well until several fights break out. Kayne and Senator Kenney reach the submarine, board her, and give the signal. S'neifa activates the forcefilm and Kayne takes the boat out of Mlayanu, leaving Don and the rest of the crew behind to be recaptured. Later Kayne and Kenney are brought into the jail, having been recaptured just after reaching the surface. Kept in a cell separate from the rest of Tritons crew, Don asks Muggins to bring him some metal tubing and tools so that he can make a tin whistle to pass the time. He then makes an ultrasonic dog whistle, which he uses to call Shep. After several incidents when Shep comes at his call the dog is chained up and then begins to howl when Don calls him. An angry mob forces K'mith and the dome technicians to allow Don to designate the dome-control building as the dog-god's shrine. Don then uses a signal generator that he had retrieved from Triton to modulate the current creating the dome forcefilm, causing a loud hum and salt rain to come from the dome and terrify the mob. Don then discovers that K'mith has had his own agenda which meshes perfectly with what Don had intended: the Atlanteans have been unable to find any more of the crystals that they need and he had hoped that scientists on the surface world might be able to make more. Don assures him that they can and will. Thus Don and the crew of the Triton are released and the Triton, fitted with a forcefilm that will allow the boat's engines to run when it is turned on, leave Myalanu with K'mith and S'neifa aboard.
