The Yarrow Plot

The Yarrow Plot was a thwarted assassination scheme whose intended target was the Imperial Residence and whose potential casualties extended far beyond the Emperor. Recounted by Duv Galeni as a case study in counterterrorism, it illustrates the kind of success that shaped Lucas Haroche’s career while remaining largely invisible outside ImpSec: the plot was stopped, but its prevention brought little public recognition, and the danger that prompted it was scarcely known beyond the agency.

The Plan and Its Target

A hyperisolationist faction aligned with Count Vortrifrani planned to use an old jump-freighter, the Yarrow, as a suicide weapon. The conspirators meant to drop it directly onto the Imperial Residence. The vessel’s impact alone would have destroyed most of the building; explosives packed aboard were intended to add to the destruction, not to make an otherwise harmless craft dangerous. The planned attack therefore threatened the heart of imperial power as well as the people inside it.

The target’s location made the danger broader than the residence itself. Duv Galeni noted that a missed drop point could have killed thousands of people in Vorbarr Sultana. Ivan Vorpatril responded that his mother’s flat was not far from the residence, making the citywide risk personal as well as political. Miles Vorkosigan, who had been off-world at the time, likewise understood the scale of the potential loss. The attack was intercepted before it occurred, but its intended trajectory left a stark uncertainty: how many people would have died if the freighter had missed its target?

The Loose Thread and the Investigation

The conspirators’ explosives became the mistake that exposed them. They provided the loose thread that led Lucas Haroche’s team to the plotters; the planned strike was thus uncovered through a trace left by the attackers’ own preparation. Duv Galeni characterized the case as a textbook example of counterterrorism, and Simon Illyan required new ImpSec analysts to study it. The account identifies the explosives as the investigative opening, without detailing the team’s subsequent methods or the precise sequence by which it traced the faction.

The thwarting of the plan had a political consequence beyond averting the attack. Count Vortrifrani distanced himself from the faction, but the episode broke up his support and left the Imperium less embarrassed by him afterward. The account does not describe his precise role in the conspiracy; it presents his alignment with the hyperisolationists and his subsequent distancing as significant political circumstances, not as a full account of his participation.

Haroche’s Career and ImpSec’s Secrecy

The Yarrow case formed part of Lucas Haroche’s record in Domestic Affairs. Simon Illyan had credited him with personal responsibility for derailing at least four serious plots against the Emperor’s life while serving as a Domestic Affairs agent, apart from the Yarrow incident. That earlier achievement won Haroche his chiefship. In the later conversation, the plot’s successful prevention is also cited as an example of the kind of expertise the agency hoped Haroche might pass on to Miles Vorkosigan, who was being considered for a future assistant posting under him.

Inside ImpSec, the Yarrow Plot was famous enough to serve as required study material; outside the agency, it was practically unknown. Miles Vorkosigan explained the asymmetry as a feature of the work: successes remained secret and thankless, while failures became conspicuous and brought blame. The plot’s place in the conversation makes that contrast concrete. Its obscurity was not evidence that the danger had been slight; it was the consequence of a successful operation whose public visibility was limited precisely because the attack had been prevented.

Significance of the Recalled Case

The Yarrow Plot is presented through a conversation about Haroche’s qualifications and the possible shape of Miles Vorkosigan’s next assignment, rather than through a dramatized account of the operation itself. Duv Galeni’s concise retelling supplies the essential stakes—the freighter, the target, the explosives, the investigative clue, and the threatened city—while the surrounding discussion shows what the case meant inside the agency. For ImpSec analysts, it was a model to learn from; for Haroche, it was part of a record of successful counterterrorism; for the public, it was nearly invisible.

That contrast also gives the episode its irony. Haroche’s success protected the Imperial Residence and potentially thousands of residents, yet its secrecy denied the operation the kind of public credit that accompanies a visible victory. The account does not turn that secrecy into a detailed institutional critique, but it does place the case within an agency culture where effective prevention can erase the very evidence of the danger. The Yarrow Plot’s lasting significance lies both in the attack that did not happen and in the quiet professional reputation built by stopping it.
