“About what?”

“My father’s disappearance. You made an appointment to meet me at the cemetery. Why did you run away?”

The bold attack was not without an effect. The woman gasped, and fumbled nervously with the key to the padlock.

“I don’t know what you’re talking about!” she muttered.

“Unless you tell me everything you know regarding my father’s disappearance, I’ll call the police!”

“The police—” the woman repeated, plainly frightened.

“Yes,” Penny went on relentlessly, “this is a serious matter. It will do you no good to bluff.”

The woman gave up trying to unlock the gate. Setting her basket down in the snow she said weakly: “You advertised a reward—”

“I’ll still be glad to pay it for worthwhile information. What do you know about my father?”

The woman drew a deep breath. “Well, I picked him up in my car after the accident.”
