The captain lowered his gaze. "We were paid to find the chest," he said. "Paid well. But maps—my employer said the maps were trouble."

"Give it," Locke said, without pretense.

They surfaced, hauling the Heart back as tide-roads slid closed behind them. When they returned, the town smelled of smoke. The south market men had come in force. Locke stood at the quay with more than traders—soldiers and hired hands ringed about him like wolves.

At the edge of the fight, a child—small, pale, with the same defiant chin Jardena wore—stepped forward and shouted for no one in particular: "Mistress Jardena! The maps—look!" The maps in Locke's satchel had come loose and unrolled in the rain, and as they hit the water they shimmered. The paper unlatched into the sea and revealed names hidden like coral: a hundred small coves whose tides still answered to Halmar's pact. As the maps spilled, the tide-roads above them answered, wrapping like bands and lifting men high. The hired men found their boots useless as their feet left the quay; currents moved them gently away, depositing them far down the shoreline where they could not regroup.

Negotiations wound like fishing line until Locke produced a counteroffer: he would return nothing unless Jardena could find and bring him the "Heart of Tiderun"—an old family relic her grandmother had hidden in the rock where the cliff meets the sea. The relic was said to temper the tide-paths, to keep them from swallowing whole coves. The name of the task was a provocation—because to retrieve the Heart one must dive where currents loop in impossible ways.

"People are missing," Jardena said. "Old promises were broken. Your maps involve Halmar. Why?"
