They were in a roofed and walled but floorless shed, built into the warehouse itself. Water surged about below them, and on it floated a five passenger plane, fully assembled and apparently ready to fly, but brand new and so far unused. "I'll look it over," said Bell, briefly.

Everything seemed trim and new and glistening in the cabin. The fuel tanks showed the barest trace of fuel. The oil tanks were full to their filling-plugs. He swung back up. "Taking a chance, of course," he said curtly. "If the motors were all right when they were tried, they probably are all right now. They may have been tuned up, and may not. I tried the controls, and they seem to work. For a new ship, of course, a man would like to go over it carefully, but if we've got to hurry...."

Also others of The Master's subjects. My treason would provoke a terrible revenge from The Master, so they thought to prove their loyalty by permitting me to disclose my plan and foil it at its beginning.
