Paramedic Jonathan Trestle has had a week of death. Every call seems to end up with someone flatlining until finally he is able to revive a disheveled patient long enough for the man to hand him a crumpled piece of paper and say, "Give this to Martin." With the simple decision to honor a dying manś last wish, Trestle soon finds himself snared in a mystery of murder and danger. His only clue is a scrap of paper covered with indecipherable dashes, but with his future, freedom, and life on the line, he must race for the truth before the 'Angel of Death' comes calling for him.
