_Opening summary of French's final reconstruction._

> He soon discovered that each falsified entry required some further manipulation to buttress it up, and in spite of all his efforts he found himself becoming more and more deeply involved.

Each fake entry needed more lies to support it, and Duke became increasingly trapped.

_Describes Duke's escalating embezzlement._

> Then Miss Winter made the slip which compassed their downfall—she forgot about the cipher letter which Duke had said he had sent, and fled, leaving the letter to fall into the hands of the police.

Cissie Winter's fatal mistake was forgetting the coded warning letter, which she left behind for the police to find.
