# John Sparewell — The Mystery of Cabin Island character guide

> John Sparewell in The Mystery of Cabin Island by Franklin W. Dixon.

**Role:** major

**Also known as:** Sparewell, this man Sparewell

**First appearance:** 0002-iii-a-strange-note

## Snapshot

A shadowy figure from the island's past whose hidden hand — and hidden treasure — turn a simple winter camping trip into a hunt for something someone will lie and trespass to find.

## Who they are

Sparewell never appears in person, but his name surfaces in the same breath as the rosewood box, the stolen stamps, and the strange interest Hanleigh and his men show in Cabin Island. He is the absent antagonist whose old crime left something valuable behind, and the question of what he hid and where is what pulls the boys deeper into the island's secrets. Every clue about Sparewell raises the stakes, because whoever understands his secret first controls the whole game.
