It's been thirty years since Marshall James last spoke to the love of his life, LAPD Homicide Detective Mac McElroy. Things had gone from bad to over and done with, when Mac had told him he was trouble times ten and the only way to survive was alone. Marshall finds an old Valentine's Day Card, the last communication between them, and he decides against the odds to see if he could get the final goodbye they'd never had. He takes us back in time to L.A., 1985, where life had seemed to be going well at last, until a corpse with a familiar face and a brutal cause of death showed up and sent them spiraling to a finish. Marshall pursues one last killer, and when it's over, the only thing he's killed is love. But is it really too late? Or could time, age, and not enough wisdom change their fate.
