The Case of the Mexican Knife

Its handle was hammered of silver coins. Its blade was a razor-sharp sliver of black obsidian. It was... THE MEXICAN KNIFE. What did it mean? FEAR...to a beautiful dancer who knew too much. HOPE...to a man who knew it could lead him to his vanished brother. TREASURE...a dream of sudden wealth for a thief who sought the secret hidden in its clumsy silver handle. MURDER...for a man who never saw it, never touched it, until its shining black tip...the blade that had once done ceremonial slaughter for ancient Aztecs...plunged through his back.
