"I used to dream about how I would take a ship if I were the Prince of Space," said Captain Brand. "I've just been talking our course of action over with him. We've agreed on a plan."

In an hour the Prince and Dr. Trainor entered the bridge. Paula appeared in a few moments. Her face was drawn and pale; unhappiness cast a shadow in her brown eyes. Eagerly, she asked the Prince how he was feeling.

"Oh, about as well as ever, thanks," the lean young man replied in a careless voice. His dark, enigmatic eyes fell upon her face. He must have noticed her pallor and evident unhappiness. He met her eyes for a moment, then took a quick step toward her. Bill saw a great tenderness almost breaking past the bitter cynicism in those dark eyes. Then the Prince checked himself, spoke shortly:

"We are preparing for action, Paula. Perhaps you should go back to your stateroom until it is over."

The girl turned silently and moved out of the room. Bill thought she would have tottered and fallen if there had been enough gravity or acceleration to make one fall.

In a few minutes a little group of flickering lights appeared among the stars ahead, just beside the huge, crater-scarred, golden disk of the moon.

"The Triton and her convoy!" shouted the men at the telescopes.

"All men to their stations, and clear the ship for action!" Captain Brand gave the order.

"Two Moon Patrol sunships are ahead, cruising fifty miles apart," came the word from the telescope. "A hundred miles behind them is the Triton, with two more Patrol fliers twenty-five miles behind her and fifty miles apart."

Brand spoke to the Prince, who nodded. And Brand gave the order.
