# M. Masseron — The Golden Triangle character guide

> M. Masseron in The Golden Triangle by Maurice Leblanc.

**Role:** supporting

**Also known as:** Masseron

**First appearance:** 0001-ii-right-hand-and-left-leg

## Snapshot

A wartime police official who trades barbs with Patrice over an unsigned note, only to find the mystery's author standing behind him in a black frock-coat.

## Who they are

Masseron is the law in a case that keeps slipping past the law: bodies, ciphers, and a gold secret tangled in the war. He bristles at Patrice's refusal to name his informant, and his dry surprise at hearing old Siméon named shows a man used to facts, not phantoms. His skepticism is the reader's anchor, the official voice that makes Don Luis's sudden, phlegmatic revelations land as both outrageous and credible.
