Andrew Harvey Books in Order

The Andrew Harvey books sit in a slightly different corner of Alan McDermott’s thriller world. Where Tom Gray often charges straight into danger from the outside, Andrew works from inside the machine. He is an MI5 operative, which means the tension here comes not just from action, but from intelligence work, political pressure, and the ugly reality that stopping an attack usually starts with fragments, guesses, and very little time.

At the center of the series is Andrew himself, a capable field man who has already crossed paths with Tom Gray in earlier books. That matters, because it gives him a useful contrast. Tom tends to operate like a weapon the system cannot fully control. Andrew is one of the people trying to hold the line before chaos breaks loose. He is professional, practical, and used to making decisions in a world where the stakes are national rather than personal, even when the cost lands heavily on individual lives.

The first Andrew Harvey novel, Trojan, throws him into a classic counterterror premise with a very modern feel. MI5 learns that a horrifying weapon may be heading for British soil, and Andrew is called in to help stop it. One of the key threads involves a refugee mother and her child, which gives the story a tense human core. This is not just a race against faceless villains. It is also a story about people being used, pressured, and pushed into impossible choices by forces much larger than themselves.

Sarah Thompson is important too. She is a fellow operative and Andrew’s partner, and together they give the book some of its best energy. Their relationship helps ground the intelligence work, and it also reminds you that in this kind of story the professional and personal can never stay neatly separated. Around them is the wider security apparatus, including bosses, bureaucratic pressures, and the kind of official oversight that can help one minute and get in the way the next.

The danger feels uncomfortably plausible.

That is really the Andrew Harvey appeal. Trojan is still an action thriller, but it leans a little more into process than the Tom Gray books do. There is more chasing leads, more trying to work out what the enemy is actually planning, and more emphasis on prevention rather than revenge. The action lands harder because it comes after the slow tightening of the net, and because the consequences of failure are so clear.

Even though there is only one main Andrew Harvey book here, it opens a strong little strand of McDermott’s fiction. If you like British intelligence thrillers, counterterror plots, and stories where fieldwork meets politics and moral compromise, this is a good place to start. It connects neatly to the wider Tom Gray world, but it also works as its own focused, high-pressure read.
