"Say, did you ever know that he made a pretty good thing out of Mrs. Carroll's window washer?" Billy asked confidentally, leaning toward her in the dark.
"He paid her five hundred dollars for it!" Susan flashed back. "Did YOU know that?"
"Sure I knew that," Billy said.
"Well--well, did he make more than THAT?" Susan asked.
"He sold it to the Wakefield Hardware people for twenty-five thousand dollars," Billy announced.
"For WHAT!"
"For twenty-five thousand," he repeated. "They're going to put them into lots of new apartments. The National Duplex, they call it. Yep, it's a big thing, I guess."
"Bill, you mean twenty-five hundred!"
"Twenty-five thousand, I tell you! It was in the 'Scientific American,' I can show it to you!"
Susan kept a moment's shocked silence.
