When a Kenyan wheat cooperative refuses to sign onto a glossy new “climate-smart corridor”, agronomist-turned-consultant Paul Smart is sent to find out why the numbers don’t add up.
What he uncovers isn’t bad bookkeeping. It’s a hidden supply chain.
Under the cover of donor-funded grain and cut flowers, ore from abandoned Rift Valley mines and “tactical enforcement assets” are moving through cold rooms, tunnels, and quiet logistics hubs, all laundered through farmers’ debts and corridor fees.
As a warehouse clerk vanishes, a storeroom burns, and trusted insiders are quietly “put on leave”, Paul is forced to choose between protecting his sources and detonating the model everyone is paid to believe in.
