Norgate moved to the door and threw it open. A waiter stood there.
"What do you want?" demanded Norgate.
The man pointed to the indicator.
"The bell rang, sir," he replied. "Is there anything I can get for you?"
"I rang no bell," Norgate asserted. "Your indicator must be out of order."
Norgate would have closed the door, but Anna intervened.
"Tell the waiter I wish to speak to him," she begged.
The man advanced at once into the room and glanced interrogatively at Anna. She addressed him suddenly in Austrian, and he replied without hesitation. She nodded. Then she turned to Norgate and laughed softly.
"You see how perfect the system is," she said. "I was followed here, passed on to your floor-waiter. You are a spy, are you not?" she added, turning to the man. "But of course you are!"
"Madame!" the man protested. "I do not understand."
