The IPCRESS File: Plot Summary

Warning: My plot summaries contain spoilers. The major spoilers are blacked out like this [blackout]secret[/blackout]. To view them, just select/highlight them.

It’s 1961. An unnamed British agent (I will refer to him as ‘Harry’, the only name he gives in the novel, though he says it is false) leaves Military Intelligence and joins a small civilian intelligence agency named WOOC(P), known as ‘Provisional’.

The head of Provisional, Dalby, welcomes Harry to his team. He tells Harry that another British scientist has disappeared, the latest of eight top-echelon personnel who have vanished in the last six weeks. He suspects a man codenamed Jay is involved and sends Harry to offer money for the scientist’s return.

Harry meets Jay and goes with him to a seedy nightclub, where he finds the missing scientist, but a police raid interrupts him. Jay and the scientist disappear again.

One of Our Scientists Is Missing

Harry travels to Beirut, followed by what he assumes are Jay’s operatives. Dalby learns Jay is going to smuggle the missing scientist over the border into Syria in the boot of a car. Dalby and Harry set up an ambush and rescue the scientist. They kill the operatives who were tailing them, who turn out to be from US Navy Intelligence.

Back in London, the police pick up one of Jay’s gang, but someone kills him before Harry can interrogate him. However, the arrest does lead Harry to a safe house, which he raids with the help of the police. In the abandoned safe house, they discover a tape with what sound like distorted human voices on it.

Dalby takes Harry to observe an American nuclear weapons test in the Pacific. There, Harry discovers that the Americans have the same problem with their scientists disappearing, and that they suspect he is a Soviet agent.

A few days later, Dalby tells Harry that the Americans have found a body on the coast road, and they go to investigate. Dalby disappears and the Americans arrest Harry, suspecting him of killing a guard and sending information about their nuclear test to a Soviet submarine offshore. The Americans interrogate Harry and then swap him with the Hungarians for two crashed spy-plane pilots. The Hungarians hold Harry and start trying to brainwash him…


Harry [blackout]realises he has to escape before the brainwashing succeeds. He manages to get out and discovers that his prison is not actually in Hungary but is in fact in London. He recovers at a friend’s flat, but Harry’s tormentors kill his friend and frame Harry for the murder.[/blackout]

Harry [blackout]goes to Dalby’s house and discovers Dalby there with Jay and the ‘Hungarian’ jailers. He follows Jay back to London, but when they arrive at Jay’s flat his associates capture him and take him to talk to Jay.[/blackout]

Jay [blackout]gets a mysterious phone call and then Military Intelligence arrive, arrest him and free Harry.[/blackout]

In [blackout]the final chapters, the reader finds out what was going on. Military Intelligence suspected Dalby was a Soviet agent, which was why they transferred Harry to WOOC(P) in the first place. Dalby was behind the plot to brainwash the scientists, and Jay was simply working for the highest bidder. Dalby tried several times to frame Harry (at the nightclub and on the American base) to draw suspicion away from himself. Dalby’s ‘rescue’ of the scientist in Lebanon was also a bluff.[/blackout]

British intelligence [blackout]kill Dalby in a fake car crash, employ Jay and promote Harry to head of Provisional.[/blackout]

The IPCRESS File: Analysis


The IPCRESS File has a Mystery plot (see Spy Novel Plots).

The ‘Mystery’ Plot

The Protagonist:

  1. Discovers a disaster perpetrated by an unknown Antagonist for unknown reasons (or is assigned to investigate by their Mentor).
  2. Makes a plan to investigate the tragedy and discover who the Antagonist is.
  3. Investigates and gathers clues suggesting who the Antagonist is.
  4. Is impeded by the Antagonist.
  5. Involves one or more Allies in their investigation (Optionally, there is a romance sub-plot with one of the Allies).
  6. Attempts to discover further clues to the identity of the Antagonist, dealing with further Allies and Enemies as they meet them.
  7. Is betrayed by an Ally or the Mentor (optionally).
  8. Discovers the identity of the Antagonist and the reasons for their actions and any wider plan.
  9. Is involved in a final confrontation with the Antagonist and stops (or fails to stop) them carrying out their plan.


The IPCRESS File is all about style. The prose is not at all the usual third-person narrated, straightforward style favoured by most espionage thriller writers. Instead, there’s an almost stream-of-consciousness, sardonic commentary from the first-person narrator as events unfold.

Unfortunately, to a current-day reader, many of the sarcastic references are now obscure. For example: “I was no Steve Reeves.” meaning the hero isn’t feeling well. Steve Reeves was a well-known bodybuilder and film star in the nineteen sixties.


Len Deighton’s approach to exposition is to be extremely cryptic all the way through the novel and then have a chapter at the end explaining everything. He does the same thing in SS-GB. As he said himself:

Using first-person narrative enabled me to tell the story in the distorted way that subjective memory provides… what happens in The IPCRESS File is to be found somewhere in the uncertainty of contradiction.

This is a risky technique, and so Len Deighton’s novels are not for everyone – what one reader finds enticing and mysterious, another will find obtuse and confusing.

Also, because of the restriction to Harry’s point of view, and his lack of understanding of what is actually going on, the ending is a bit of a letdown, not just because the antagonist gives up without a fight, but also because it’s effectively a deus ex machina.


Like The Spy Who Came In From the Cold, The IPCRESS File was to an extent a reaction to the success of James Bond.

The IPCRESS File reacts to the upper-class, ‘champagne and spying’ lifestyle portrayed in the Bond novels by showing a down-at-heel Britain, a cynical protagonist, and an espionage world as concerned with claiming expenses and navigating office politics as investigating enemy plots.

Reality: MKULTRA

MKULTRA is the closest known real project to IPCRESS. It was an illegal CIA programme to develop drugs and torture techniques for use in interrogation and mind control. Trials included forcing people to take LSD and other drugs and subjecting them to continuously looped audio messages, hypnosis, sensory deprivation, and other mental and physical abuses to ‘brainwash’ them in a similar manner to IPCRESS.

The IPCRESS File: My Verdict

A triumph of style, and written unlike any other spy-thriller. A classic.

The IPCRESS File: The Movie

Michael Caine in the IPCRESS File

The IPCRESS File was filmed in 1965, starring Michael Caine as ‘Harry Palmer’ and directed by Sidney J. Furie.

The movie of The IPCRESS File captures the essence of the novel despite only using elements of the plot. It drops the sections of the novel in the Lebanon and on the American base, with the action set entirely in London. The movie plot focuses more on the brainwashing than the novel does, and the dénouement is completely different.

Michael Caine makes the film with a great performance as the sarcastic, cynical, bespectacled Harry Palmer, in only his second big role.
