They reached the blue door without being bothered, though. Vickers stared at the sign:
INTERNATIONAL SPY RING
INCORPORATED
Secrets Bought and Sold
It was the one place in Luna City where the ISP couldn't reach him. But would the ring give him sanctuary? He didn't know.
"They will," he thought; "they will, by Heaven, or take the consequences!"
He said: "Here's where I leave you, officer. Thanks for the lift," and slid out of the patrol boat.
The ISP man had guts. Vickers had taken his automatic, but the agent reached for the emergency guns in the locker. Before he could shoot, though, Vickers had disappeared through the blue door.
He sprang from the patrol boat, started after him. He was three feet from the blue door when it vanished.
Inside the reception room, Vickers balanced on the balls of his feet, the ISP agent's automatic in his hand. His mouth was a thin line. Except for Vickers, the room was empty.
He was about to raise his nictitating lids when the door of the inner office opened and Tani flew to meet him. Involuntarily, he jerked up the automatic, but the girl didn't even notice it.
