Method: the first comparison records only the verifiable change in form: one published novel becomes a six-episode season. Story-level differences will be added only when a specific novel edition and specific released episode can both support the assertion.

Comparison 01 · separate continuities

Slow Horses (2010) → Series 1

Form difference
Book note — no plot spoilers

The official Mick Herron bibliography records Slow Horses as the first Slough House novel, published in 2010.

Television note — no plot spoilers

Apple’s programme listing divides Series 1 into six individually titled episodes. That episode structure is a screen-only container, not the novel’s chapter structure.

Dead Lions (2013) → Series 2

Form difference
Book note — no plot spoilers

The official bibliography records Dead Lions as the second Slough House novel, published in 2013.

Television note — no plot spoilers

Apple’s listing presents Series 2 as six episodes. The guide therefore compares episode evidence with the novel rather than assuming a chapter-for-episode match.

Form difference
Book note — no plot spoilers

The official bibliography records Real Tigers as the third Slough House novel, published in 2016.
