# Doctor Walker — The Circular Staircase character guide

> Doctor Walker in The Circular Staircase by Mary Roberts Rinehart.

**Role:** supporting

**Also known as:** young Doctor Walker, Walker, this Doctor Walker, XX Doctor Walker, this young Walker, Young Walker

**First appearance:** 0000-i-i-take-a-country-house

## Snapshot

The fashionable young physician, rumored fiancé of Louise, whose plans for a house at the foot of the hill Rachel cannot verify and cannot forgive.

## Who they are

Doctor Walker is known to Rachel only through gossip — a Stanhope car, a chauffeur named Riggs, a summer spent hovering near the Armstrongs, and a supposed engagement to Louise that no one will confirm. His rumored house on the property, drawn by Huston in town, proves impossible to trace, and Rachel's instinctive dislike hardens into suspicion. He hovers at the edge of the case as the man whose intentions toward Louise may explain far more than anyone admits.
