Focus in the dungeon bypass pipe hub and the four-minute return walk to Sister Merrow’s washroom turned squarely to the chalked three-step valve-cycling diagram Ada drew directly on the stone pier beside the saint niche before handing Hesta the brass T-wrench as Ada Morland and thirty-eight-year-old Hesta and Pella Rook and Foreman Eren Tal addressed the question of cycling the bypass and leaving on time. With one minute left on her twenty-four-minute site glass, Ada teaches Hesta how to cycle the backup bypass cock to bleed the twelve-pound pulse into the river tail-race. Then leaves right on time to cross back to Harrowby.
The technical core of cycling the bypass and leaving on time needed honoring the twenty-four-minute sand-glass without a second’s pause. Handing the wrench to the trained local head laundress rather than playing the indispensable hero and risking a threshold overrun. Throughout this phase of the scalding grey-water surge beneath Hesta’s Southern Bridge washhouse, the crew held fast to treating an old vaulted dungeon as a civic plumbing problem rather than a monster lair. Every brass fitting, every stitched seam. Every thirty-minute lunch crossing had to answer to physical measurement rather than guild politics.
“Twenty-three minutes on the site glass, Ada—four minutes to walk back to Fish Street!” Pella called clearly from the stair landing. She held up the brass stopwatch even though the eight-sided grate was the biggest historical discovery of the month.
