The Key Under the Mat

Look closely at the plan’s architecture: rescue is provided for Jacob, none for Simon himself; the message will go out in three hours; the key is taken outside — “so that even Simon himself could not free Jacob if he changed his mind”. He is building barricades not against Jacob — against his own will to live.

This is the most important thing to see in this chapter: a person does not defend against something that isn’t there. Simon knows that a part of him will want to change his mind — and ties its hands in advance. This split lives inside almost every suicidal design, and it is exactly where help gets its grip: the part he builds barricades against is the part that wants to live.
