Cold rain battered the ancient windows while detectives entered the grand foyer through the wooden door near abandoned furniture stacks. Inspector Vance studied the rigid corpse beneath a flickering chandelier suspended above the marble floor while assistants documented wounds nearby. A playing card rested inside the victim's cold hand while the detective opened the locked drawer without making any sound. Three terrified suspects waited upstairs inside the dimly lit study while the rain continued falling outside beyond the glass windows. The elderly librarian shivered when she discovered the peculiar message written clearly across the dusty mirror beside the broken clock. Something sinister occurred within these walls during the midnight hours and only truth could finally reveal the hidden killer today.
