"The painting is genuine," Mrs. Dillon insisted. "I have proof of it."
"What proof, may I ask?"
"The picture was viewed by an expert—a man whose judgment I trust implicitly. He assured me that it was genuine."
"This expert looked at your picture since it was delivered to the house?"
"No, at the studio."
"What studio?" Penny asked quickly.
"I will tell you if you promise not to betray me to the police."
"I came here today because I wanted to help you, Mrs. Dillon. I have no intention of going to the authorities if it can be avoided."
"The studio is on Franklyn Street," the woman informed. "On an upper floor."
"Do you have the exact number of the building?" Penny asked quickly.
