“Don’t you dare start that old curiosity of yours to percolating!” Louise chided severely. “We’re not going in there!”

“Who ever thought of such a thing?” grinned Penny. “Now I wonder what time it is?”

“About eight-thirty or perhaps a little later. Why?”

“Do you remember that card we found in the leather billfold? The notation read, ‘The Green Parrot, Tuesday at 9:15.’”

“So it did, but the appointment may have been for nine fifteen in the morning.”

“You dope!” laughed Penny. “Louise, we’re in wonderful luck finding this place at just this hour! Why, the man we followed here may be the one who lost the billfold.”

“All of which makes him a saboteur, I suppose?”

“Not necessarily, but don’t you think we ought to try to learn more?”

“I knew you’d try to get me into that place,” Louise complained. “Well, I have more sense than to do it. It might not be safe.”

“I shouldn’t think of venturing in unescorted,” Penny assured her. “Why not telephone my father and ask him to come here right away?”
