"Look!" exclaimed Carroll, pointing.

The men from the morgue had the body raised in the air. And then, in
the gleam from the electric lights there was revealed underneath and in
the left side of the dead woman a clean slit through her light dress--a
slit the edges of which were stained with blood.

"Another wound!" exclaimed Daley, his newspaper instincts quickly
aroused by this addition of evidence of mystery. "This is getting
interesting!"

"It's a cut--a deep one, too," murmured Carroll, as he drew nearer to
look. "Wonder what did it?"

"Shouldn't wonder but it was done with this!" and Thong held out, on
the palm of his large hand, a slender dagger, on the otherwise bright
blade of which were some dark stains.

"Where'd you get it?" demanded Carroll.

"Over on the watch repair table."

Darcy gasped.

"Is that your dagger?" snapped Carroll at the jewelry worker.

"It isn't a dagger--it's a paper-cutter--a magazine knife."

"Well, whatever it is, who owns it?" The words were as crisp as the
steel of the stained blade.
