“There are apt to be seven or eight, if not more,” declared Judy. “But Blackberry can explore places we can’t. The trouble is, he can’t tell us what he finds—”

“Me-aurr!” interrupted the cat.

“In words, I mean,” Judy corrected herself. “You tell us in your own way, don’t you, Blackberry? I wish you could tell us how you got here. Did Peter bring you?”

“Peter wouldn’t bring a cat to help him investigate a crime,” Horace began. “Maybe you didn’t shut Blackberry in the attic—”

“Blackberry!” cried Judy as the cat leaped from her arms.

It was a squirrel that had attracted him. He soon chased it up a tree and out on an overhanging branch. The squirrel escaped, but Blackberry was now on the other side of the fence. With one leap, he was on the ground.

“A good idea!” approved Horace. “Blackberry is leading the way again. That’s how we’ll get over. You’re next, Judy. I’ll hold you up.”

“It seems to me we’re doing it the hard way. Oh, my goodness!” she exclaimed when she was in the tree. “I can see the house from here. Those policemen are just coming out. Do you think they’ll recognize your car?”

“Probably,” replied Horace. He was having a little more difficulty climbing the tree since there was no one to boost him.

“Do you think they’ll search the grounds?”
