"I don't know about 'moderate,'" said Melanie. "It's what the most expensive hotels always say."

"Yes, and 'Domestic Problems'?" said Eric. "Don't they usually mean rows between husband and wife? Admiralty, Probate and Divorce stuff?"

"I suppose so," said Tubby. "But it would be impossible to put up anything that could not be misunderstood by someone. In connection with 'Beck and Call' I think 'Domestic Problems' might stand. And, after all, if a wife did come to complain of her husband there would be no great harm done; she would simply be told that that kind of business was not transacted and sent off to the nearest police court or solicitor."

"But you could charge her for it just the same," said Eric. "After all, knowing who is the nearest or best divorce solicitor is very special knowledge and ought to be well paid for."

"Yes," said Tubby, "I've lived in the same house for two years, but I'll be hanged if I know where the nearest police station is, or the nearest fire station, or the nearest pawnbroker. Those are the valuable facts of life, and I am ignorant of all of them. I know where my own doctor lives, and my own dentist, but I haven't a notion where there is a strange one handy. And of course dentists never work at night. The address of a good dentist who would answer a night call would be worth a tenner to anyone. You ought to specialize in that, Ben."

"I will," said Ben. "You are being very useful to me. Go on."

"The best of everything," said Eric, hastily cutting in, "is a good thing to know. It takes a lot of finding out oneself. I've got a haberdashery chap, for instance, who is absolutely useless with socks. His vests are good, his shirts, his collars; but his socks are disgraceful. Very dear, and no wear in them at all. 'Advice as to the best shops for everything' would be a great line for you."

"I saw a shop the other day," Tubby said, "where there were Chinese birds' nests in the window. For soup. I'll give you the address, Ben. That will be something to start on."

"Yes," said Melanie, "and I know the best place for rings and bracelets made of elephants' hair. For luck, you know. You'd better make a note of that."
