Focus Multimedia today announced the retail release of Mystery in London: On the Trail of Jack the Ripper, a hidden object game for the PC licensed from Big Fish Games. In the game, during a trip to London, you will discover a very old and valuable copy of Robert Louis Stevenson’s Strange Case of Dr Jekyll & Mr Hyde. Between its covers there is a note, signed J.R., and you can bet it's not from that Dallas dude. Visit their website for more details.
