“Thank God for measles!” wailed Diana. Bobbie wiped his streaming forehead. “I’ve a good mind to take the remainder of this money away,” he said, “I don’t like it being in the house.” For answer, she opened the drawer of the desk and took out the black-muzzled Browning. “Burglars are my specialty,” she said. “Would you mind putting that lethal weapon away?” said Bobbie. “What a bloodthirsty little devil you are!” “I am,” said Diana. “There’s murder in my bones at this particular moment. Yes, Eleanor?” “Are you going to see Mr. Superbus?” “I didn’t know he was here. Ask him to come in, will you?” Mr. Superbus came, in his stately, senatorial fashion, and was introduced to Bobbie. It was obvious he sought a very private interview indeed, but Diana explained in what relationship Bobbie stood. “I’m sorry to have missed Mr. Selsbury,” said Julius. “Information having come to me last night through my secret agent about a certain party.” “You mean Double Dan?” Diana reacted instantly. For the moment she hadn’t a care in the world. “It’s no laughing matter, miss.” Mr. Superbus shook his head, and invited, with a wave of the hand, bent forward to see his feet and sat down slowly. “No, it isn’t any laughing matter, ma’am--miss. If he walked in at that door”--he pointed--“made up for the part, you’d think it was your father.” Diana raised a protesting hand. “May I explain, in passing, that Mr. Selsbury is not my father?” Julius graciously indicated that she had his permission. “Dan is wonderful! I was telling my good lady only this morning that, if she sees a fellow looking like me trying to get into the house when I’m supposed to be away, she must make him take his shirt off--I’ve got a lucky mole on my shoulder, miss--ma’am--miss. Why moles are supposed to be lucky I’ve never discovered.” 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. “I see. She’s a sort of decoy who gets to know the victim.” “Know him! Well, I should say she did, miss--it would be much easier to tell you everything if you was ma’am.”
