"Not until I see you film the big slide," he replied. "I wish you all success."

"Seen anything of Alcando's alarm clock model lately?" asked Joe, after a pause.
"Not a thing, and I haven't heard it tick. Either he has given up working on it, or he's so interested in the pictures that he has forgotten it."
