CHAPTER XIV
A MEAN ENEMY
"You have invented something yourself?" repeated Frank, with a good deal of curiosity.
"Yes," nodded Markham.
"What is it?"
"A puzzle."
"What kind of a puzzle?" pressed Frank.
"I’ll show it to you," said Markham, fishing in his pocket. "There it is. I don't suppose it's much," he continued in a deprecating way, "though two or three fellows who saw it said it was quite clever."
Frank inspected the article his companion now handed him with a good deal of interest. It was roughly made of wire. There was a ring linked into a triangle, and the latter linked onto two other rings. The lower one of these had a link connected with a wire square. Lying loose around this link was a larger ring of wire.
"What's the puzzle?" inquired Frank, looking over the little device.
