# Mr. Wertheimer — The Lone Wolf character guide

> Mr. Wertheimer in The Lone Wolf by Louis Joseph Vance.

**Role:** supporting

**Also known as:** Wertheimer

**First appearance:** 0000-i-troyon-s

## Snapshot

A methodical operative whose oilcan and biplane are as much tools of his trade as his cool appraisal of other men's souls.

## Who they are

Wertheimer works the gray zone between criminal enterprise and official service, a man who can shake hands with a thief and mean it while still keeping his professional distance. His willingness to let Lanyard and Lucy Shannon walk away at the end—and his refusal to know which direction they take—reveals a pragmatist with a code of his own. He matters because he embodies the ambiguous moral machinery against which Lanyard measures himself.
