Tenacity is a first novel that reads like a sequel. Danielle “Dan” Lewis was captured by a serial killer four years before the novel begins. The novel frequently refers to that traumatic time in Dan’s life. In fact, so much reliance is placed on the past that I wondered if Tenacity was recounting events that took place in an earlier novel, but that isn’t the case.
Dan now works as a naval investigator for Crimes Involving Loss of Life (known as “Kill”), a division of the Special Investigation Branch. She starts the novel damaged -- both by the serial killer and by another violent incident in her life -- and she isn’t handling her damage very well.
Dan is assigned to look into an apparent suicide of Stewart Walker on the HMS Tenacity, a nuclear submarine. Dan feels pressure from certain naval officers to determine that the death was, in fact, a suicide. She also feels pressure to keep her nose out of a related police investigation into the murder of Walker’s wife. Of course, following a formula familiar to thriller readers, Dan decides that pursuing justice is more important than following orders.
Dan is teamed with John Granger, who assisted her in the Hamilton investigation. That unhappy relationship creates a source of tension that gives the story an added kick.
The story milks some drama from the fact that the submarine sets sail with Dan as the only female on board. The captain and most of his company are offensively sexist. Her investigation is obstructed at every turn. Her naval career is threatened. Can she find a way to make justice prevail?
The book does not paint a flattering portrait of submariners in the British navy but, given the author’s credentials, I suspect it is accurate. In any event, the detailed submarine setting adds a sense of authenticity to the story.
The story is a bit too heavily dependent upon coincidence, but that’s common in modern thrillers. Dan is a sympathetic character. Supporting characters are one-dimensional but that is also common in thrillers. The story develops a reasonable amount of suspense and moves at a reasonable pace. The ending holds some surprises. The story does not resolve every loose end, apparently setting up a sequel, but it does resolve the main storyline in a satisfying way. In short, Tenacity is a reasonably strong and enjoyable debut novel.
