W: I enjoy going through second-hand bookstores, don’t you? It’s interesting to see what people used to enjoy reading. Did you see this old book of children’s stories?
M: Some of these books are not so old, see? This mystery was published only six years ago. It costs 75 cents. You can’t beat that.
W: Here, look at this.
M: What? Are you getting interested in the 19th century poetry all of a sudden?
W: Everything on that shelf is worth 50 cents. But if this is the signature of someone who was well-known, it might bring a lot more. I hear William Shakespeare’s signature is worth about a million dollars.
M: Oh, I can hardly read what that one says. Who wrote it?
W: The name looks like Harold Dodgson, maybe. Wasn’t he a politician or something? I am going to buy this book and see if I can find a name like that in the library.
M: Good luck. Your poetry may make you rich, but I’ll bet my 75-cent mystery is a better buy.
