Rain lashed the old mansion’s windows on that stormy night. Inspector Davies knelt beside the body in the library. The victim, Lord Harrington, stared blankly at the ceiling. A shattered window pane let the cold, wet air inside. His prized antique revolver was missing from the display case. A single, leather-bound book lay stained beneath his outstretched hand. The grandfather clock in the hall struck midnight ominously. Only three people were in the house when it happened. The storm had knocked out the telephone lines earlier. Something terrible had happened in this quiet, wealthy estate.
