D4: Dark Dreams Don't Die - Season 1 - Guides

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. In her last breath, she told him to “Look for D.” From that moment on, the search for 'D' became Young's whole life – nothing more, nothing less.
Suddenly, he receives a case that might be related to 'D.' This case revolves around a courier for a drug called “Real Blood” who vanished after coming forward to testify against a drug lord known as “D.” Apparently, he vanished from thin air while being escorted to Boston in an airplane.
Finding the vanished courier could lead to the identity of 'D.' If Young obtains a memento that could take him back to that fateful day… then perhaps he’d be able to change his destiny.
And so, David Young dives into the case of the vanishing courier, as the wheels of fate begin to churn once more...
