Diana turned to Bobbie.
“This is rather alarming.”
“Oh, I don’t know,” said Bobbie. “Lots of people have moles.”
“Don’t be absurd. I mean Double Dan.”
“But why should he come here?” asked Bobbie, well aware that the contents of the safe, such as they were, justified a visit. But it was Mr. Superbus who answered.
“That’s what they all say, but there’s always a reason, miss. My good lady said to me ‘Why should he come here?’ but I pointed out that—what’s in that safe? Any valuables there?” He pointed to the wall.
“Nothing very much,” said Diana hastily. “Tell us some more about this person, Mr. Superbus.”
Mr. Superbus smiled to himself.
“I’m the greatest living authority on him,” he said modestly, “that’s what I am! He’s a very plausible fellow, and works with a girl. Whether or not—well, let’s say it’s his wife. She wangles the information out of the fellow that Dan is going to rob. Do you see?”
Diana nodded.
