Take it from me, it was slick!" The Jovian guffawed loudly as he added, "What would their faces be like if they knew that John Dark and his crew are still living? That it was John Dark himself who sent us here?" "Be quiet, you idiot!" ordered Kenniston hastily. "Do you want the whole Patrol to hear you?"
