“I think it might be fun to be caught out in one—just so long as it’s not the real thing.”

“I want to get home before the street lights are turned out,” Louise insisted. “In fact, I promised Mother I’d come straight home when the library closed.”

“Oh, all right,” Penny gave in reluctantly.

The girls began to walk faster for they were many blocks from their own street. Now and then they met an air raid warden and so knew that the time for the test blackout was close at hand.

“Louise!” Penny suddenly exclaimed, stopping short.

“Now what?” the other demanded. “Don’t you dare tell me you’ve left something at the library!”

Penny was staring at a man who only a moment before had come through the revolving doors of the Hotel Claymore.

“See that fellow!” she said impressively.

“Yes, what about him?”

“He’s the head waiter at The Green Parrot.”
