Edge of Darkness

Widowed Boston Police Detective Thomas Craven thought he knew his only offspring, twenty-four year old Emma Craven, the two who had a seemingly loving, communicative father-daughter relationship. He begins to possibly doubt that belief when in Boston on vacation from her current base of nearby Northampton, Emma, displaying signs of a serious medical condition, tells her father that she should have told him "this" a long time ago implying it having to do with the reason for her vomiting, but she is never able to as she is soon after gunned down in cold blood outside the family home as they are on the way to the hospital emergency by an unknown perpetrator who is able to escape. With Tom's colleagues believing he was the intended target, Tom is officially on the case solely to provide his insight as to who might want to kill him. But without telling his colleagues, he instead follows leads pertaining specifically to Emma. He begins to believe that her death relates to something having to do with her work as an intern at Northmoor, an R&D company, her job which she never spoke of as she signed a confidentiality agreement with the company. One piece of the puzzle is the mysterious Englishman who shows up in Tom's backyard one evening, seemingly with a certain agenda before getting there, he deciding not to follow through with that agenda by the time he leaves. As Tom gets closer to figuring out the entire conspiracy, often working outside of the law, he knows that his life is in danger, but he hopes he can avenge Emma's death regardless of what happens to him.
