“No, Horace, it was the other time, when I thought the fountain was enchanted and made my wishes. I know I saw flashes of gold in the water. I wonder if any of these fish are ever kept there.”

“Probably—in the summer. In the winter the pool seems to be reserved for more valuable things. I wouldn’t mind fishing for diamonds. There may be more—”

“Sh!” Judy stopped him. “Wasn’t that the doorbell?”

Horace looked out the window. The two policemen who had been cruising around the grounds were no longer in the police car. It was parked in the circular driveway. The bell rang again. Blackberry stiffened in Judy’s arms and pricked up his ears. She could hear Stanley’s voice.

“Mrs. Cubberling is resting. She does not wish to be disturbed this morning.”

“Is she Cubby’s wife or his mother?” Judy whispered.

“Who knows? Mr. Cubberling may be the neighbor I’m looking for,” declared Horace. “Listen!”

“Two government men were here last night,” Stanley was saying. “Mrs. Cubberling can’t tell you any more than she told them.”

Judy’s gray eyes widened in alarm when she heard this. The FBI! Had she accidentally stumbled into a mystery Peter was investigating?

“I didn’t mean to!” she exclaimed. “Oh, Horace! One of those government men could have been Peter. What’ll we do? I promised him I’d never follow him on another one of his investigations.”
