Robert Harris is a British novelist and former journalist best known for historical thrillers built around political power, espionage, war, institutions, and moments when private decisions alter public events.
His bibliography is much simpler than those of many prolific genre authors.

Only one major fiction sequence needs to be read in strict order: the Cicero Trilogy. Almost every other Robert Harris novel is a standalone.
That means new readers do not need a complicated master chronology. The main task is knowing where the Cicero books belong and avoiding a few alternate-title traps.
The One Series You Must Read in Order
The Cicero Trilogy follows Roman statesman Marcus Tullius Cicero through the final decades of the Roman Republic.
Read:
- Imperium (2006)
- Lustrum (2009)
- Dictator (2015)
This is both publication order and recommended order.
The trilogy is narrated by Cicero’s secretary Tiro and follows one continuous political and personal arc. Later volumes assume familiarity with alliances, rivalries, elections, trials, marriages, betrayals, and political crises established earlier.
Do not begin with Dictator.
Lustrum and Conspirata Are the Same Book
This is the main title issue in Harris’s bibliography.
The second Cicero novel was published in the UK as:
Lustrum
The US edition was published as:
Conspirata
They are the same novel.
The trilogy is therefore not:
- Imperium
- Lustrum
- Conspirata
- Dictator
It is:
- Imperium
- Lustrum, also titled Conspirata
- Dictator
Readers buying used books or mixed UK and US editions should check the underlying title before assuming they are missing a volume.
Should Pompeii Be Read Before the Cicero Trilogy?
No.
Pompeii is another Robert Harris novel set in ancient Rome, but it is not part of the Cicero Trilogy.
It takes place in AD 79, more than a century after Cicero’s death.
The book follows an engineer responsible for the Aqua Augusta aqueduct as Mount Vesuvius approaches its eruption.
There is no continuing character or plot connection requiring Pompeii before Imperium.
Pompeii: Standalone
Cicero Trilogy: Separate continuity
Where Does Agrippa Fit?
Agrippa is Robert Harris’s next novel, scheduled for publication on August 27, 2026.
It returns to ancient Rome and follows Marcus Vipsanius Agrippa and his relationship with Octavian, the future Augustus, during the violent transformation of the Roman Republic.
Although Agrippa’s historical period follows the events covered in the Cicero Trilogy, the book is being published as a separate novel.
It should not currently be labeled Cicero Book 4.
Chronologically, readers interested in Harris’s Roman settings could use:
- Imperium
- Lustrum
- Dictator
- Agrippa
- Pompeii
That is a historical sequence, not a formal series order.
For a first read, each project can remain separate.
Robert Harris Novels in Publication Order
Harris’s fiction bibliography is compact enough that publication order is useful as a career overview.
- Fatherland (1992)
- Enigma (1995)
- Archangel (1998)
- Pompeii (2003)
- Imperium (2006)
- The Ghost (2007)
- Lustrum (2009)
- The Fear Index (2011)
- An Officer and a Spy (2013)
- Dictator (2015)
- Conclave (2016)
- Munich (2017)
- The Second Sleep (2019)
- V2 (2020)
- Act of Oblivion (2022)
- Precipice (2024)
- Agrippa (2026, forthcoming)
Only Imperium, Lustrum, and Dictator need to remain together for story continuity.
The rest can be selected according to subject or historical period.
Robert Harris World War II Novels
Several of Harris’s standalones deal directly with the Second World War or Nazi Germany.
They are not connected stories.
Fatherland
Fatherland (1992) was Harris’s first novel.
It is alternate history set in 1964 in a world where Nazi Germany won the Second World War.
A German police investigator becomes involved in a murder case that threatens the regime’s carefully maintained version of history.
Status: Standalone
Enigma
Enigma (1995) centers on codebreaking and espionage around Bletchley Park during the war.
It is historical fiction rather than alternate history.
There is no connection to Fatherland beyond Harris’s interest in wartime secrecy.
Status: Standalone
Munich
Munich (2017) takes place during the 1938 Munich Conference involving Neville Chamberlain, Adolf Hitler, and the political crisis over Czechoslovakia.
It occurs before the Second World War itself.
Status: Standalone
V2
V2 (2020) follows parallel British and German characters during the V-2 rocket campaign of 1944.
It does not continue Enigma or Munich.
Status: Standalone
Should the World War II Books Be Read Chronologically?
They can be, but there is little reason to do so.
A broad historical order would be:
- Munich
- Enigma
- V2
- Fatherland
Fatherland belongs last only because its fictional setting is 1964.
However, it occupies an alternate timeline in which Nazi Germany won the war, so it does not actually continue the historical world of the other three books.
Publication order is just as valid.
Fatherland Is Not the Start of a Series
Because Fatherland was Harris’s debut and was highly successful, some readers assume later World War II novels form a loose continuation.
They do not.
Fatherland, Enigma, Munich, and V2 are separate novels.
Recurring subject matter is not shared continuity.
Archangel
Archangel (1998) follows a British historian in post-Soviet Russia who becomes involved in a mystery connected to Stalin.
It is a standalone political and historical thriller.
There is no sequel.
It also has no narrative connection to Fatherland despite both dealing with twentieth-century dictatorships.
The Ghost
The Ghost (2007) follows a professional ghostwriter hired to complete the memoirs of a former British prime minister.
The novel is a contemporary political thriller rather than part of Harris’s historical fiction.
It was adapted into the film The Ghost Writer.
Some editions and film-related references therefore use the phrase “Ghost Writer,” but Harris’s original novel title is The Ghost.
Do not count The Ghost and The Ghost Writer as separate novels.
The Fear Index
The Fear Index (2011) is a standalone techno-thriller set around algorithmic trading in Geneva.
It follows scientist and hedge-fund operator Alex Hoffmann as an automated trading system begins behaving in increasingly disturbing ways.
No other Harris novel is required beforehand.
Status: Standalone
An Officer and a Spy
An Officer and a Spy (2013) is Harris’s novel about the Dreyfus Affair.
The story follows French army officer Georges Picquart as evidence emerges that Alfred Dreyfus was wrongly convicted of espionage.
It takes place in France in the 1890s.
It is not part of the Cicero Trilogy despite also using real historical figures and political intrigue.
Status: Standalone historical novel
Conclave
Conclave (2016) follows the secret process of electing a new pope after the death of a fictional pontiff.
The action is concentrated around the Vatican and the College of Cardinals.
It is completely self-contained.
Readers who discovered Harris through the film adaptation can begin directly with the novel.
Status: Standalone
The Second Sleep
The Second Sleep (2019) initially appears to be set in a medieval society.
Its true setting and the history behind that society are central to the novel’s mystery, so reading detailed chronological descriptions beforehand can reduce the intended effect.
It has no sequel.
Status: Standalone
Act of Oblivion
Act of Oblivion (2022) is set after the English Civil War and Restoration.
It follows two men wanted for their involvement in the execution of Charles I as they attempt to evade capture in New England.
The novel takes place centuries before most of Harris’s other historical thrillers.
No companion book is required.
Status: Standalone
Precipice
Precipice (2024) is Harris’s latest published novel as of August 8, 2026.
It is set in 1914 and centers on the relationship between British Prime Minister H. H. Asquith and Venetia Stanley as Europe moves toward the First World War.
Sensitive government information becomes entangled with their correspondence.
The novel stands on its own.
Status: Latest published novel
Continuity: Separate
Agrippa
Agrippa is scheduled for August 27, 2026.
It follows Marcus Agrippa and Octavian in the aftermath of Julius Caesar’s assassination and during the struggle that transforms Rome from republic to imperial rule.
Because the release date is still in the future as of this update, the correct status is:
Forthcoming
Do not list it as Harris’s latest published novel yet.
Once released, it will become his seventeenth novel.
Robert Harris Novels by Historical Setting
Readers who prefer choosing by era rather than publication date can group the books this way.
Ancient Rome
- Imperium
- Lustrum
- Dictator
- Agrippa, forthcoming
- Pompeii
The first three form the Cicero Trilogy.
Agrippa and Pompeii are separate novels.
Seventeenth Century
- Act of Oblivion
Late Nineteenth Century
- An Officer and a Spy
Early Twentieth Century
- Precipice
- Munich
- Enigma
- V2
This is a broad historical sequence rather than a shared storyline.
Alternate Twentieth Century
- Fatherland
Postwar and Contemporary Settings
- Archangel
- The Ghost
- The Fear Index
Speculative Future
- The Second Sleep
This grouping is useful for selecting a subject, not for continuity.
A Robert Harris Historical Chronology
If you want to arrange the historical novels approximately by when their events occur, use:
- Imperium
- Lustrum
- Dictator
- Agrippa
- Pompeii
- Act of Oblivion
- An Officer and a Spy
- Precipice
- Munich
- Enigma
- V2
- Archangel
The placement of Fatherland is deliberately excluded because its 1964 belongs to an alternate history.
The Ghost and The Fear Index are contemporary thrillers.
The Second Sleep requires enough structural ambiguity that placing it in a simple historical list risks undermining part of the novel.
Chronological order is therefore a curiosity, not the recommended first reading plan.
Robert Harris Nonfiction Books in Order
Before becoming primarily known as a novelist, Harris published several nonfiction books as a journalist.
- A Higher Form of Killing: The Secret Story of Gas and Germ Warfare (1982), with Jeremy Paxman
- Gotcha! The Government, the Media and the Falklands Crisis (1983)
- The Making of Neil Kinnock (1984)
- Selling Hitler: The Story of the Hitler Diaries (1986)
- Good and Faithful Servant: The Unauthorized Biography of Bernard Ingham (1990)
These books are separate from his fiction.
They do not need to be read before Fatherland.
A Higher Form of Killing
Harris co-wrote A Higher Form of Killing with Jeremy Paxman.
It examines the history of chemical and biological warfare.
Later editions may carry slightly altered subtitle wording, but they are not sequels.
Status: Nonfiction
Gotcha!
Gotcha! The Government, the Media and the Falklands Crisis examines British media and government during the Falklands War.
It was published in 1983.
Status: Nonfiction
The Making of Neil Kinnock
The Making of Neil Kinnock examines the Labour politician around the period in which he became party leader.
It is not a novel or political-thriller series entry.
Status: Nonfiction
Selling Hitler
Selling Hitler: The Story of the Hitler Diaries examines the notorious fake Hitler diaries scandal.
It is one of Harris’s best-known nonfiction works.
The book is unrelated to Fatherland despite both involving Hitler and historical deception.
Status: Nonfiction
Good and Faithful Servant
Good and Faithful Servant focuses on Bernard Ingham, Margaret Thatcher’s press secretary.
It was published in 1990, shortly before Harris moved decisively into fiction.
Status: Nonfiction
Robert Harris Complete Fiction Reading Order
Readers who simply want every novel in publication order can use:
- Fatherland
- Enigma
- Archangel
- Pompeii
- Imperium
- The Ghost
- Lustrum
- The Fear Index
- An Officer and a Spy
- Dictator
- Conclave
- Munich
- The Second Sleep
- V2
- Act of Oblivion
- Precipice
- Agrippa, forthcoming
This works perfectly well because the standalones do not interfere with one another.
The one exception is that readers who begin Imperium may prefer to finish Lustrum and Dictator before returning to the publication sequence.
A Better Reading Plan Than Strict Publication Order
If you are new to Harris, a subject-based route is usually more satisfying.
For Political Historical Thrillers
- Fatherland
- An Officer and a Spy
- Munich
- Precipice
These are independent, so the order is flexible.
For Ancient Rome
- Imperium
- Lustrum
- Dictator
- Pompeii
Add Agrippa after its publication if you want another Roman political novel.
For World War II
- Enigma
- Munich
- V2
Fatherland can then be added as an alternate-history variation on the period.
For Modern Institutional Thrillers
- The Ghost
- The Fear Index
- Conclave
Again, these do not share characters.
Robert Harris Short Fiction
Harris’s bibliography is overwhelmingly novel-length.
One notable short story is:
PMQ
It appeared in the anthology Speaking with the Angel, edited by Nick Hornby.
The story is optional and has no continuity connection to Harris’s novels.
It should not be inserted into the Cicero Trilogy or treated as a missing standalone novel.
Is The Ghost Writer a Robert Harris Book?
Not under that exact original novel title.
The novel is The Ghost.
The film adaptation was released as The Ghost Writer, and Harris co-wrote the screenplay with Roman Polanski.
Readers searching by the film title may therefore encounter editions or listings using both terms.
For bibliography purposes, count one novel:
The Ghost
Are Robert Harris’s Books Connected?
Almost all are not.
The only major continuing fiction sequence is:
- Imperium
- Lustrum
- Dictator
Those three form the Cicero Trilogy.
Everything else is normally a standalone.
Some novels revisit similar subjects, especially Nazi Germany, British politics, ancient Rome, and state secrecy, but recurring historical interests do not create shared continuity.
Is Agrippa Part of the Cicero Trilogy?
No confirmed publisher description makes Agrippa a fourth Cicero novel.
It is another ancient-Roman historical novel by Harris, set in the generation immediately after Cicero.
Readers of the trilogy may find it a natural next Roman book, but it should remain separately labeled.
Cicero Trilogy: Complete
Agrippa: Separate forthcoming Roman novel
Is the Cicero Trilogy Complete?
Yes.
The trilogy consists of:
- Imperium
- Lustrum
- Dictator
Dictator completes the sequence.
Agrippa does not change that status.
Which Cicero Title Should US Readers Buy?
US readers may find the second volume under the title Conspirata rather than Lustrum.
The correct US-style order is therefore:
- Imperium
- Conspirata
- Dictator
That is exactly the same trilogy as:
- Imperium
- Lustrum
- Dictator
Do not buy both Lustrum and Conspirata unless you deliberately want two editions of the same novel.
What Was Robert Harris’s First Novel?
Fatherland, published in 1992, was his first novel.
Before that, he was already an established journalist and nonfiction author.
His nonfiction career began a decade earlier with A Higher Form of Killing in 1982.
What Is Robert Harris’s Latest Published Novel?
As of August 8, 2026, the latest published Robert Harris novel is:
Precipice (2024)
It remains the newest available novel because Agrippa has not yet reached its publication date.
What Is Robert Harris’s Next Book?
Agrippa is scheduled for publication on August 27, 2026.
It is Harris’s return to ancient Rome and centers on Marcus Agrippa and Octavian after Julius Caesar’s assassination.
Until August 27, it should be labeled forthcoming rather than published.

The Simplest Robert Harris Reading Order
Robert Harris is one of the easier major thriller writers to navigate.
If you pick up Fatherland, Enigma, Archangel, Pompeii, The Ghost, The Fear Index, An Officer and a Spy, Conclave, Munich, The Second Sleep, V2, Act of Oblivion, or Precipice, you can simply start reading. None requires another novel first.
Only one sequence needs discipline:
- Imperium
- Lustrum, also called Conspirata
- Dictator
That trilogy should remain intact.
Agrippa will offer another route into Harris’s ancient Rome when it is published on August 27, 2026, but it is a separate novel rather than a fourth Cicero installment.
For most new readers, the easiest decision is therefore thematic rather than chronological: choose the period that interests you, and only worry about order when you reach Cicero.
