At the time when Jack the Ripper terrorized London, Sir Robert Anderson worked as Chief of the Criminal Investigation Department of Scotland Yard. He was knighted upon retirement in 1901, but his greatest accomplishment was writing perhaps the most influential book on messianic prophecy in history. Anderson expounds upon the famous "70 weeks" prophecy of Daniel 9, conclusively demonstrating the supernatural source of the Bible by it's fulfilled prediction of the exact time in history when the Messiah was to appear.
