The rain hammered the old manor as midnight struck twelve. A scream tore through the halls before silence returned again. Detective Marlowe found the cold body beside the grand staircase. Fresh blood stained the old carpet in a dark pool. Nobody in the house claimed to hear the fatal argument. The locked library window suggested an inside killer still waited. Every nervous guest had a motive and an airtight alibi.
