"I will attempt to show that the defendant did produce a living duplicate of himself after which he killed the duplicate. I call for my first witness the inventor of the device, Timothy Woodart."

Tim came to the stand and was sworn. There was considerable questioning to establish the qualifications of the witness, during which Cranshaw said to Foster: "This will be a thin case, Foster. Yet, if we can establish a reasonable doubt, the result will be an acquittal."

"Thin nothing," laughed Foster. "Just tie 'em up as I told you!"

"All right," replied Cranshaw uncertainly. "But it will be like arguing on one side for part of the time and then switching sides in the middle."

"What do you care so long as we win?"

"I don't," grinned Cranshaw. "Listen—Woodart is starting to give pertinent testimony."

"Mr. Woodart," asked Jones, "is it possible for your device to be stopped at such a time as to leave a complete set?"

"Yes," said Woodart.

"And you've known this all along?"

"Naturally. I invented it."
