Concens

Concens are places in Britain where groups of S.1s—important chemists, physicists, electronics engineers, political advisers, and others considered essential to the country’s operation—were found together. Carswell coined the term for these concentrations while investigating patterns among senior figures; they became a potentially significant clue, but not an explanation in themselves.

Identification and Investigation

Carswell’s analysis began with an apparent contradiction: the people in the groups showed few similarities within any one occupational or geographical category, yet similarities emerged when the groups were compared across those categories. He charted where the S.1s gathered and found concentrations in places that were neither holiday centres nor conference venues. The locations, rather than a single shared profession or region, gave the pattern its name.

Dalby assigned Carswell to work with the narrator, and Carswell and Sergeant Murray examined the S.1s rather than the much larger population of S.2s or the small number of cabinet-level figures. Their work was methodical, but Carswell’s statistical approach could not turn every correlation into a meaningful conclusion. The narrator asked him to describe both a Concen and an S.1 from the figures, making the scattered observations legible as a profile while leaving their cause open.

Patterns and Limits

Some common factors seemed striking at first: owning two cars, taking long holidays, visiting America, and holidaying in North Africa. Yet the S.1s were already similar in age, income, and education, so such habits might arise from those shared circumstances rather than from any hidden connection. Carswell and Murray therefore had to distinguish patterns that merely reflected the group’s social profile from behaviours harder to account for.

Among the people concentrated at Concens, an above-average number had belonged to political or quasi-political groups; all but one of these groups had right-wing aims. Other recorded characteristics included a serious illness during the previous five years for quite a few individuals, often a fever; no left-handed people among the Concens; many bachelors; and a slightly higher-than-average number of decorations for valour. Public-school attendance and divorced parents, by contrast, appeared at average levels. These contrasts supplied a more particular description, but the evidence did not establish what had produced the concentrations.

Relation to the Disappearance Inquiry

The search for a pattern among S.1s took place against concern about the disappearance of senior scientists. The kidnapping of Raven, an important S.1, showed that an individual could be abducted for his value: Jay had taken him and nearly delivered him across the border before the British team recovered him at Baalbek. But there had been no further kidnappings at the point when Carswell’s findings were discussed, and the gatherings at Concens looked like a different, still unexplained phenomenon.

Dalby cautioned against treating the statistical profile as proof of Jay’s involvement. He considered it plausible that Jay might seize an S.1 occasionally for money, but thought the scale suggested by Carswell’s analysis was incompatible with that explanation. Without more concrete evidence, the Concens remained an investigative lead rather than a demonstrated operation or a solved conspiracy.

Narrative Significance

Concens give the investigation a name for a pattern before it has a cause. Their mixture of mundane correlations, unusual personal characteristics, and politically suggestive affiliations encourages suspicion, while the narrator’s and Carswell’s inability to establish what the clusters mean preserves uncertainty. The concept marks the boundary between detecting that people gather in unexpected places and proving why they do so.
