Rain fell heavily upon the dark streets of old London. Inspector Vance stared grimly at the cold, lifeless body. Blood pooled slowly beneath the chair in the quiet study. A shattered porcelain cup lay near the victim's stiff hand. Heavy velvet curtains blocked the pale light of the moon. No signs of forced entry appeared anywhere in the room. The grandfather clock ticked loudly against the oppressive morning silence. Someone had silenced the wealthy old man forever tonight. Vance adjusted his heavy woolen coat and took a breath. This strange puzzle would test his sharp intellect very soon.
