"Mr. Smith9." the man said.
"That's right," Henry said. "Can I help you?"
"I have some good books. You buy books, don' t you?"
"Yes. Bring them in. I' 11 have a look at them. "
Soon the books were on the table. "Crone in now," Henry called out, "and bring the list."

"Come with me, sir," the policeman said to the man.
