"Perhaps her hat pin is poisoned," suggested Chick.
"I don't think that."
"Or possibly—"
"Wait a moment. Look at this box."
"Well?"
"That wrapper was punctured while still on the box," explained Nick. "Notice that the pin went through the spaces in this metal design, and then through the silk lining inside."
"Plainly enough, Nick."
"Notice this particular puncture in the interior of the lining."
"By Jove! there's a faint tinge of red around it."
"Left when the pin was withdrawn," whispered Nick, significantly. "Chick, it's a tinge of blood!"
