Gerald Seymour Books in Order (Updated September 8, 2026)

Gerald Seymour is a British thriller writer and former television journalist whose novels draw heavily on terrorism, intelligence work, organised crime, insurgency, espionage, military operations, and international political conflict. His first novel, Harry’s Game, appeared in 1975 after years of reporting from conflict zones for ITN.

For most of his career, Seymour wrote standalone thrillers rather than a conventional recurring-character series. That changed with Jonas Merrick, an understated MI5 intelligence officer who first became the central recurring figure in The Crocodile Hunter and has since appeared in a continuing sequence.

This makes the reading order straightforward: the earlier novels can generally be read independently, while the Jonas Merrick books should be kept in publication order.

The Fastest Way to Choose a Gerald Seymour Starting Point

Best classic starting point: Begin with Harry’s Game if you want to start with Seymour’s breakthrough novel and his early treatment of the Northern Ireland conflict.

Best modern series starting point: Begin with The Crocodile Hunter if you want Jonas Merrick and a true continuing sequence.

If you prefer to sample the standalones by subject rather than publication date, titles such as The Contract, A Line in the Sand, Holding the Zero, A Deniable Death, and Battle Sight Zero all work without previous reading.

Jonas Merrick Books in Order

Jonas Merrick is Seymour’s principal recurring protagonist. He is an experienced MI5 intelligence analyst whose low-profile manner contrasts with the dangerous operations he helps design and control.

1. The Crocodile Hunter (2021)
2. The Foot Soldiers (2022)
3. In at the Kill (2023)
4. The Best Revenge (2024)
5. A Duty of Care (2025)
6. The Irregular (2026)

Recommended order: Read these six books in publication order. Although each operation has its own immediate threat, Merrick’s professional position, methods, relationships, and reputation develop across the series.

The Irregular is the sixth Jonas Merrick novel and the forty-second Gerald Seymour novel overall.

Upcoming Jonas Merrick Book

A seventh Jonas Merrick novel, A Rumour of Paradise, is scheduled for publication on January 14, 2027.

The novel is set to place Merrick against a Russian sleeper network operating in Britain, while another storyline reaches back toward a figure from his past.

Upcoming: Place A Rumour of Paradise after The Irregular once published.

Gerald Seymour Standalone Novels in Publication Order

Before Jonas Merrick became a recurring lead, Seymour produced a long sequence of independent thrillers. The following books do not form one continuous storyline.

1. Harry’s Game (1975)
2. The Glory Boys (1976)
3. Kingfisher (1977)
4. Red Fox (1979), also published in the United States as The Harrison Affair
5. The Contract (1980)
6. Archangel (1982)
7. In Honour Bound (1984)
8. Field of Blood (1985)
9. A Song in the Morning (1986), also published in the United States as Shadow on the Sun
10. At Close Quarters (1987), also published as An Eye for an Eye
11. Home Run (1989), also published as The Running Target
12. Condition Black (1991)

31. Vagabond (2014)

34. A Damned Serious Business (2018)
35. Battle Sight Zero (2019)
36. Beyond Recall (2020)

Separate continuity: These novels are not numbered installments in one large series. Similar intelligence agencies, military organisations, terrorist movements, criminal networks, or geopolitical settings do not mean the books share a continuing protagonist.

Harry’s Game and the Northern Ireland Thrillers

Harry’s Game was Seymour’s first novel and grew directly from his experience reporting on the Troubles in Northern Ireland. It follows an intelligence operation aimed at identifying and killing an IRA gunman.

The book is a Standalone. Seymour later returned repeatedly to Northern Ireland and related political violence, but he did not write a direct Harry sequel.

Books such as Field of Blood, The Journeyman Tailor, and Vagabond also deal with Northern Irish conflict or its legacy, but they feature different plots and characters.

The Glory Boys

The Glory Boys, published in 1976, was Seymour’s second novel. It is an international terrorism thriller and does not continue the characters from Harry’s Game.

It can be read entirely on its own. Its proximity to Harry’s Game in Seymour’s career sometimes leads readers to expect a sequel, but there is no shared main continuity.

Kingfisher, Red Fox, and The Contract

Seymour’s next three novels continued his movement through international political thrillers.

1. Kingfisher (1977)
2. Red Fox (1979)
3. The Contract (1980)

These are three separate stories. Reading them in publication order gives a clear sense of Seymour’s development as a novelist, but there is no plot reason to do so.

Red Fox and The Harrison Affair

The Harrison Affair is the American title for Red Fox.

Do not count both titles. They refer to the same Gerald Seymour novel.

A Song in the Morning and Shadow on the Sun

A Song in the Morning was published in Britain in 1986. American editions used the title Shadow on the Sun.

These are the same novel, so Shadow on the Sun should not appear as an extra book in a complete Seymour reading order.

At Close Quarters and An Eye for an Eye

At Close Quarters, published in 1987, also appeared under the title An Eye for an Eye.

Again, the title change reflects edition history rather than a second story.

Home Run and The Running Target

Home Run was published in 1989. It was retitled The Running Target for the American market.

Readers collecting both British and American editions should treat these as duplicates.

The Waiting Time and Dead Ground

The Waiting Time, published in 1998, was also issued under the title Dead Ground.

It is another example of why Gerald Seymour bibliographies can appear to contain more novels than the author actually wrote.

Gerald Seymour’s 1990s Thrillers

The 1990s produced a particularly varied run of standalone thrillers.

1. Condition Black (1991)
2. The Journeyman Tailor (1992)
3. The Fighting Man (1993)
4. The Heart of Danger (1995)
5. Killing Ground (1997)
6. The Waiting Time (1998)
7. A Line in the Sand (1999)

None of these requires the previous book. The sequence moves across terrorism, espionage, organised crime, political violence, and personal revenge rather than following one continuing agency or hero.

From Holding the Zero to The Walking Dead

Seymour opened the twenty-first century with another group of standalones that moved between war zones, intelligence operations, crime networks, and political violence.

1. Holding the Zero (2000)
2. The Untouchable (2001)
3. Traitor’s Kiss (2003)
4. The Unknown Soldier (2004)
5. Rat Run (2005)
6. The Walking Dead (2006)

No shared order required: Each can be selected as a separate thriller.

Later Standalones Before Jonas Merrick

1. Timebomb (2008)
2. The Collaborator (2009)
3. The Dealer and the Dead (2010)
4. A Deniable Death (2011)
5. The Outsiders (2012)
6. The Corporal’s Wife (2013)
7. Vagabond (2014)
8. No Mortal Thing (2016)
9. Jericho’s War (2017)
10. A Damned Serious Business (2018)
11. Battle Sight Zero (2019)
12. Beyond Recall (2020)

This run leads directly into the period when Seymour began using Jonas Merrick as a continuing central character.

Is There a Gerald Seymour Chronological Order?

No master chronology is needed. The standalone novels are set in different conflicts, countries, political situations, and criminal environments.

Reordering them according to the historical date of each plot would not create a meaningful shared continuity and could obscure the development of Seymour’s writing across nearly five decades.

The Jonas Merrick novels already progress in publication order, so there is no reason to rearrange that series chronologically.

Recommended Gerald Seymour Reading Routes

Seymour’s bibliography is large enough that choosing by subject is more useful than reading forty-plus novels straight through.

1. For Northern Ireland: begin with Harry’s Game.
2. For Cold War political thrillers: try The Contract or Archangel.
3. For sniper and battlefield suspense: try Holding the Zero.
4. For intelligence operations: try A Deniable Death.
5. For a modern recurring series: start Jonas Merrick with The Crocodile Hunter.
6. For a complete author read: use publication order from Harry’s Game onward, while treating the first thirty-six novels as standalones.

Gerald Seymour’s Current Release Status

Gerald Seymour remains an active novelist. The Irregular, published in January 2026, is his forty-second novel and the sixth Jonas Merrick book.

The next confirmed novel is A Rumour of Paradise, scheduled for January 14, 2027. It is planned as the seventh Jonas Merrick book.

This means the Merrick series is ongoing rather than complete.
