Seven months after Solomon Hatch's arrest — October, the same month the WSS epilogue closes — Selena Varga's practice receives its third client referral. The referral uses the name of a DOJ prosecutor she knows. Within forty-eight hours she has confirmed the prosecutor did not make the referral. Within three weeks, the graph visualization she builds from the case's corporate ownership data produces a pattern she has seen before — because she built the methodology that can see it. The pattern is the Meridian network's founding architecture, reconstructed from documentation of her own methodology by someone who had fourteen months of access to Marcus's archive during the evidence management period. The countermeasures are technically correct in every element except one: an architectural anomaly that only exists because of something Marcus did in the original archive that no one outside Selena's knowledge of her brother's working method would know to replicate. Marcus built a tell into every network he documented. He called it the notational signature. Selena knows what it is. And she has just seen it in a network that Marcus never analyzed.
