A Search for Stolen Cash

A Search for Stolen Cash
French’s assignment
French says he works for creditors seeking money allegedly taken by Harkness. He wants Don to use his access to the property and people around it.
A plausible skepticism
Don points out that financial assets would usually be held in accounts, not stored as cash in a house. His reasoning cannot establish what is hidden, but it exposes the mismatch in French’s theory.
Coleman’s Missing Battery

Coleman’s Missing Battery
An oversized installation
Mike Coleman describes a large solar array, transparent photovoltaic film and a flow battery installed for Harkness. He cannot account for the battery’s location or the property’s extraordinary power demand.
Two investigations overlap
Coleman wants to sell the discovery to creditors, while Don refuses to betray the owner’s interests. The missing equipment nevertheless strengthens the link between the building and the sealed room.
A Room Built for Power

A Room Built for Power
Energy as infrastructure
The independent supply is not simply a luxury feature. It supports a concealed system powerful enough to start a chain reaction in nanobots.
The money’s real destination
Harkness’s disputed funds have helped build a technical operation rather than a conventional private fortune. The battery mystery turns into evidence of a plan with consequences for the world.
French’s Search Becomes a Hostage Crisis

French’s Search Becomes a Hostage Crisis
From investigation to coercion
French and Zlenko hold Fran to force Don to reveal the location of the money. The demand is no longer a commercial inquiry but a direct threat against a person.
A false solution
Jack offers millions to purchase her release, while French still hopes the room contains information valuable to his clients. Both sides misread how central the room is.
The Computer Behind the Door

The Computer Behind the Door
The safe’s purpose
Jack tells Don that a safe behind Far West contains a switch that opens the steel door. French expects access to Harkness’s assets and codes.
A different secret
The room is tied to a system designed to trigger Cascade, not merely to a cache of cash. Keeping the door closed becomes more important than satisfying the creditors’ search.
