Penny had not intended to speak of what she had seen at the Harrison estate. The slip of tongue made it necessary to tell of the path by the gate, the retreating figure, and the mysterious light.

“That’s funny,” commented the photographer, regarding her with a peculiar expression. “Since I’ve been on duty at the observation tower I’ve never seen any activity at the estate.”

“I don’t believe in ghosts, but I saw one all that same!” Penny insisted. “Just watch some night and see for yourself!”

Annoyed by Salt’s smile, she shifted gears and drove on down the street. Turning to Louise, she asked earnestly: “You believe I saw something wandering about the estate last night, don’t you?”

“Well,” Louise hesitated, unwilling to offend her chum. “You must have been quite upset after failing to meet that woman at the cemetery. Under the circumstances....”

“I was as calm as I am now,” Penny cried indignantly. “I saw it, I tell you!”

“Of course you did, dear,” Louise soothed. “Do please watch your driving more carefully, or I’ll have to take over.”

Penny suddenly relaxed. “Okay, have it your own way,” she shrugged. “I wouldn’t believe Mose Johnson, so why should you believe me? It’s just one of those things.”

For a long while they rode in silence. Few cars were on the road and there was little business activity at Kamm’s Corner. Penny parked in front of the Mattie Williams’ garage.

“What excuse will we have for questioning her?” Louise asked dubiously.
