The door will close, he despaired. They'll be too late.
Then, suddenly, he felt the portal drawn back and heard Blue Two speak.
"What does Robert wish?"
"Throw this heap out the door!" gasped Robert.
Amid a trampling of many feet, the major-domo was raised bodily by Blue Two and another pair of Robert's machines and hustled outside. Since the grip on Robert's wrist was not relaxed, he involuntarily accompanied the rush of metal bodies.
"Catch the door!" he called to Blue Two.
When the latter sprang to obey, the other two took the action as a signal to drop their burden. The pink-and-blue robot landed full length with a jingling crash. Robert was free.
With the robots, he made for the entrance. Hearing footsteps behind him as the major-domo regained its feet, he slipped hastily inside.
"Pick up that toolbox!" he snapped. "When that robot stops in the doorway, knock its head off!"
Turning, he held up a finger.
