The Robot moved its huge square head and raised an arm with a vague gesture.

"What do you want?"

It advanced, and stood before us, its dangling arms clanking against its metal sides. In one of its hands the ray-cylinder was clutched, the wire from which ran loosely up the arm, over the huge shoulder and into an aperture of the chest plate where the battery was located.

"Closer, Migul."

"I am close enough."

The cylinder was pointed directly at us.

"What do you want?" the Robot repeated.

Mary smiled. "Just to talk to you," she said gently. "To tell you how foolish you are—a big strong thing like you!—to let Tugh control you."
