"Human squirrels, I suppose," Susan smiled. "When I came up you were craning your neck at that man over by the oak tree."
"What became of him?" Penny demanded anxiously, turning to look.
She had talked with Susan scarcely a minute, yet the museum workman had disappeared. In vain she scanned the park. He was nowhere to be seen.
"I thought you were interested in him!" Susan proclaimed triumphantly.
"Of course I was!" Penny cried impatiently. "He was that same museum workman we met at the Gage Galleries."
"Not the one you suspected of stealing the Rembrandt?"
"Yes, and he was talking with—" Penny suddenly checked herself.
"What were you saying?"
"He was talking with a girl," Penny finished. "I intended to follow the man. Now it's too late."
"I guess it was my fault. But I didn't suppose you were really shadowing anyone. I'm sorry if I ruined everything."
