D4: Dark Dreams Don't Die

This is the story of a man with a very strange fate. His name is David Young – formerly with the Boston PD Narcotics Unit, now a private detective. He possesses the supernatural ability to “dive” into the world of the past by touching left-behind items called “mementos.” Two years ago, Young’s wife was killed by an unknown assailant, and Young suffered a blow to the head that cost him his memory.
