“I carry a camera with me,” he said, amusedly. “Those were the tracks of the tripod, a rare beast in captivity.”

“And does the cave really go clear through the island to the castle?” asked Ruth, eagerly.

Isn’t that so, Polly?”

“Well, there are ‘deceptions’ to every rule, you know Aunty Welcome says,” laughed Polly. “I wouldn’t say positively, but I do think that the Doctor is a darling.”
