# Polton — The Red Thumbmark character guide

> Polton in The Red Thumbmark by R. Austin Freeman.

**Role:** supporting

**Also known as:** the ingenious Polton, X Polton

**First appearance:** 0001-the-red-thumbmark

## Snapshot

Thorndyke's ingenious laboratory assistant, whose quiet competence with boxes, microscopes, and micrometers turns his employer's forensic theories into courtroom-ready fact.

## Who they are

Polton keeps the machinery of Thorndyke's practice running, receiving terse instructions about boxes and portfolios with a speculative, unflappable efficiency. He is the gatekeeper of the chambers, announcing visitors like Inspector Miller while never quite revealing how much he understands. His value lies in making the abstract tangible: when Thorndyke needs apparatus for court, Polton is the one who ensures the right tools arrive, quietly enabling the defence's scientific gambits.
