Irina has the document on the table when we arrive. The original correspondence from 1997, the administrative record of the trust instrument's establishment, the one that registered a provision for a minor heir not publicly acknowledged. At the bottom of the document, below the notarization, two signatures. Marre's. And a witness signature: M. Haugen, with an address in the city where Petra grew up. The city where Vera lived when she was carrying Petra. Gregor is at the table. He has the look he has when a calculation has just resolved and the result is significant. "I processed a payment in 1997," he says. "Through the personal layer, the same layer as Vera's instrument and the one for Lucien. A smaller payment not an instrument, a single transaction. To an address in the same city."
