Thomas Gifford Books in Order (Updated September 9, 2026)

Thomas Gifford was an American thriller writer whose novels moved through political conspiracy, Cold War espionage, Vatican intrigue, historical secrets, Hollywood crime, legal suspense, and murder mysteries. He also published under the names Thomas Maxwell, Dana Clarins, and Lisa Drake.

Most of Gifford’s books are standalones, but three continuities matter for reading order. John Cooper appears in The Wind Chill Factor and The First Sacrifice. Ben Driskill appears in The Assassini and Saint’s Rest. Under the Thomas Maxwell name, Lew Cassidy stars in Kiss Me Once and Kiss Me Twice.

Readers who want the best-known Thomas Gifford experience can start with The Wind Chill Factor for neo-Nazi conspiracy, The Assassini for Vatican suspense, or The Glendower Legacy for an alternate historical secret involving George Washington and the Cold War.

Three Series That Need an Order

1. John Cooper: read The Wind Chill Factor first and The First Sacrifice second.
2. Ben Driskill: read The Assassini before Saint’s Rest.
3. Lew Cassidy: read Kiss Me Once before Kiss Me Twice.

Everything else can generally be selected independently, although publication order is useful for readers following Gifford’s development from conspiracy thrillers into pseudonymous mysteries and later international suspense.

John Cooper Books in Order

1. The Wind Chill Factor (1975): John Cooper becomes entangled in a conspiracy involving surviving Nazi networks, political power, old wartime loyalties, and a hidden effort to preserve the ideology of the Third Reich long after Germany’s defeat.
2. The First Sacrifice (1994): Twenty years later, Cooper is drawn back to Germany after his estranged sister asks for help finding her missing son and he discovers that the neo-Nazi threat he once fought has moved into the open under a charismatic new leader.

Read these in order. The second novel explicitly depends on Cooper’s history from the first book and shows how the events he once believed finished have continued to shape his life.

Why The Wind Chill Factor Is the Best Gifford Starting Point

The Wind Chill Factor was Gifford’s first novel and established the combination of history, political paranoia, international conspiracy, and personal danger that would recur throughout his career.

John Cooper is not a professional super-spy. He is forced into a hidden political world in which wartime ideology has survived through people who understand that influence, money, and secrecy can sometimes accomplish what armies cannot.

The novel won Putnam’s prize for best first novel and became one of the titles most strongly associated with Gifford.

The First Sacrifice Revisits Cooper Two Decades Later

The First Sacrifice was published almost twenty years after The Wind Chill Factor, but the long gap is part of the story rather than evidence of a reboot.

Cooper has tried to bury his past by operating a Boston movie house and retreating into old films. His sister’s message from Germany forces him back toward the country and ideology that damaged his earlier life.

Her son has disappeared, neo-Nazi violence is spreading, and her husband Wolf Koller has become an important figure in a movement presenting an updated version of the political threat Cooper thought he had already defeated.

Series endpoint: Gifford did not publish a third John Cooper novel.

Ben Driskill Books in Order

1. The Assassini (1990): Lawyer Ben Driskill investigates the murder of his sister, Sister Valentine, and discovers an ancient organization of assassins once used by powerful figures within the Catholic Church.
2. Saint’s Rest (1996): Driskill returns when the suspicious death of presidential confidant Drew Summerhays leads toward a conspiracy involving intelligence agencies, political extremists, and an attempt to remove the President of the United States.

Publication order is required. Saint’s Rest brings back the protagonist readers first meet in The Assassini, even though the conspiracy changes from Vatican power to American politics.

The Assassini and the Vatican Conspiracy

The Assassini is set in 1982 while the Vatican prepares for the death of Pope Callistus IV and the struggle over his successor.

In Princeton, Sister Valentine is murdered inside a family chapel. Her brother Ben Driskill becomes convinced that the Church will not conduct a genuine investigation, so he begins one himself.

The search leads to a document hidden in an Irish monastery and evidence of the Assassini, a secret brotherhood of killers historically employed by princes of the Church.

The central mystery is not simply whether the organization still exists, but who controls it during the current Vatican power struggle.

Saint’s Rest Moves Driskill into American Politics

Saint’s Rest takes place in a near-future United States and begins with the unexplained death of Drew Summerhays, an elderly man close to President Charles Bonner.

Bonner has threatened to dismantle or weaken intelligence organizations that have accumulated power behind the scenes. Driskill, who works at Summerhays’s law firm, is pulled into the investigation after the President seeks help.

The conspiracy soon suggests that an organized group is willing to remove the President rather than surrender the hidden influence it believes essential to national survival.

Final Ben Driskill book: No third novel followed before Gifford’s death in 2000.

Lew Cassidy Books as Thomas Maxwell

Gifford used the Thomas Maxwell name for several 1980s novels, including two books featuring Lew Cassidy.

1. Kiss Me Once (1986): Lew Cassidy enters a mystery involving murder, deception, dangerous relationships, and secrets that turn what appears to be a personal case into a more complicated criminal investigation.
2. Kiss Me Twice (1988): Cassidy returns for a second suspense case in which another web of crime, hidden motives, and personal danger tests the investigator introduced in the first novel.

Kiss Me Once was nominated for a Macavity Award. Readers interested in Gifford’s mystery-oriented work should keep both Lew Cassidy novels together rather than treating the Thomas Maxwell name as a different author.

The Cavanaugh Quest

• The Cavanaugh Quest (1976): Reporter Paul Cavanaugh becomes obsessed with the mysterious Kim Blankenship, a widow whose relationships with men repeatedly end in sudden death, forcing him to decide whether he is investigating a victim, a killer, or something more complicated.

The novel was nominated for the 1977 Edgar Award for Best Novel.

Cavanaugh’s professional instinct tells him to investigate the pattern of violence surrounding Kim, but his growing attraction to her makes objective judgment increasingly difficult.

Standalone: Paul Cavanaugh does not continue into another Gifford series.

The Man from Lisbon

• The Man from Lisbon (1977): Inspired by the real Portuguese fraudster Alves Reis, the novel follows a brilliant forger who rises from poverty and colonial disappointment to create one of the most extraordinary financial frauds of the twentieth century.

Reis begins by falsifying credentials and documents before realizing that his skill can operate on a much larger scale.

His ambitions eventually involve counterfeit financial authority, banks, governments, currency, and a scheme large enough to threaten confidence in Portugal’s economic institutions.

Historical-fiction standalone: It is based on a real criminal case rather than connected to Gifford’s modern conspiracy series.

The Glendower Legacy

• The Glendower Legacy (1978): Harvard professor Nat Underhill becomes the target of KGB operatives after evidence surfaces suggesting that George Washington attempted to sell military intelligence to the British during the American Revolution.

The historical mystery begins at Valley Forge in 1778, where a Continental soldier witnesses an act of treason and is framed and executed to protect the real offender.

Two centuries later, a descendant discovers evidence capable of damaging one of America’s foundational national myths. Soviet intelligence sees the document as a propaganda weapon and kills to obtain it.

The novel was adapted into the 1981 film Dirty Tricks.

Hollywood Gothic

• Hollywood Gothic (1979): Oscar-winning screenwriter Toby Challis survives a prison-plane crash while serving time for murdering his wife and secretly returns to Los Angeles under a changed appearance to discover who actually killed her and framed him.

The novel shifts Gifford away from international conspiracy toward Hollywood crime, scandal, studios, celebrity, and private secrets.

Toby could simply disappear after surviving the crash, but clearing his name matters more than escape. He therefore returns to the same world that condemned him and begins investigating from the shadows.

Standalone mystery: There is no Toby Challis sequel.

Dana Clarins Novels in Order

Gifford published three suspense novels under the Dana Clarins name during the mid-1980s.

1. Woman in the Window (1984): A woman becomes drawn into a mystery shaped by observation, suspicion, hidden relationships, and danger that turns an apparently ordinary domestic or social setting into a suspense story.
2. Guilty Parties (1985): Relationships, secrets, responsibility, and criminal suspicion collide as several people discover that guilt can extend beyond the person who physically commits a crime.
3. The Woman Who Knew Too Much (1986): Knowledge of a dangerous secret places a woman at the center of a suspense plot where powerful people have strong reasons to prevent what she knows from becoming public.

These books are separate novels rather than one Dana Clarins trilogy. The pseudonym groups them bibliographically, not through recurring characters.

Other Thomas Maxwell Novels

1. The Saberdene Variations (1987): Victor Saberdene’s carefully constructed ambitions lead into crime, law, money, and deception as apparent innocence repeatedly gives way to darker motives beneath the surface.
2. The Suspense Is Killing Me (1990): Gifford uses the Thomas Maxwell identity for another crime and suspense novel in which danger, mystery conventions, and hidden motives create a more playful variation on his thriller style.

Neither title belongs to the Lew Cassidy sequence.

The Medical Center Murders as Lisa Drake

• The Medical Center Murders (1984, as Lisa Drake): Written with Otto Penzler from an outline by Edward D. Hoch, this hospital-based mystery places murder inside a medical institution where professional relationships and access create a contained field of suspects.

This is another pseudonymous work and should not be confused with the Dana Clarins novels published during the same period.

Praetorian

• Praetorian (1993): American journalist Rodger Godwin becomes involved in a secret British wartime assassination operation against Rommel and spends years trying to identify the traitor responsible for the mission’s destruction and the death of General Sir Max Hood.

The novel ranges across Europe and North Africa during World War II while also moving backward into the characters’ earlier lives.

Godwin’s relationship with Max Hood’s wife Cilla complicates his obsession with discovering who betrayed the Praetorian operation.

Standalone historical espionage: It does not connect to John Cooper despite sharing World War II and conspiracy themes.

Alternate Names Do Not Mean Different Writers

• Thomas Gifford: the main name used for his political, historical, and international thrillers.
• Thomas Maxwell: used for the Lew Cassidy books and other suspense novels.
• Dana Clarins: used for three mid-1980s suspense novels.
• Lisa Drake: used for The Medical Center Murders.

A complete Thomas Gifford bibliography should therefore include all of these names rather than treating the pseudonymous books as unrelated authors.

Start with The Wind Chill Factor and The First Sacrifice if you want one complete conspiracy arc. Then read The Assassini and Saint’s Rest for Ben Driskill’s two investigations.

After those, the standalones can be chosen by subject. The Glendower Legacy mixes American history with Cold War espionage, Praetorian uses World War II assassination, Hollywood Gothic turns to Hollywood murder, and The Man from Lisbon fictionalizes a spectacular real financial fraud.

Readers completing the entire bibliography should then add the Thomas Maxwell, Dana Clarins, and Lisa Drake books, keeping the two Lew Cassidy novels together while treating the remaining pseudonymous works as standalones.
