The garland for the Seven-Bridge Walk rose up the ship's mast, hauled hand over hand by two sailors, and the whole quay roared and clapped beneath the red towers of the castle. Greta clapped too, forgetting the basket strapped to her back, and that was the moment Senator struck. The fat white goose stretched his neck flat, hooked his orange beak under the basket flap, and yanked out a whole crusty loaf before bolting down the cobbles with his wings half-spread. Rolls bounced free and rattled between the moored herring boats as he ran. "He's got the loaf! Stop him!" Greta shrieked, clogs clattering as she gave chase. Tobias swung his long lamplighter's pole low, trying to block the goose's path, while Frau Mathilde hitched up her striped skirt and lumbered after them, ear-trumpet banging against her chest. Senator ducked under a coil of rope, skidded round a fish barrel, and vanished behind a boat hull, still clutching the bread tight in his beak, bell jingling with every triumphant stride.

The mail coach thundered onto the Krämerbrücke, its wheels drumming the planks louder than thunder, and the raised drawbridge timbers shuddered under the weight. A fat roll of papers, tied loosely with scarlet ribbon, bounced clean off the back and burst apart, scattering sheets into the wind like startled birds. Greta dropped her basket and stamped down with her clunky wooden clogs, pinning one sheet, then another. Tobias swung his brass-tipped pole flat across three more, hooking a fourth out of the air with the little claw before it sailed over the rail into the Pregel below. Frau Mathilde planted her sea-boots wide and sat her whole broad self on a stubborn corner of paper, ear-trumpet swinging. Senator, delighted, chased a scrap with his neck stretched flat, bell jingling, and trapped it under one orange foot. Puffing and pink-faced, the plump man in the plum coat and green eyeshade came stumbling after his papers, clutching his crooked wig.

The spiral stair was barely wider than Greta's shoulders, each stone step worn to a shiny curve, and the four of them climbed it single file, hands pressed flat against cold walls twice as tall as Euler. Tobias went first, his lamplighter's pole scraping the low ceiling, his long green scarf trailing down behind him like a ribbon of river weed. Frau Mathilde hauled herself up by the rope handrail, puffing, her ear-trumpet swinging wildly at her chest. At the top they squeezed through the louvre window, a slatted opening as wide as a door, and Euler began counting bridges on his ink-stained fingers below. Then Tobias turned too fast. His scarf whipped round the thick bell rope hanging through the floor, yanked tight, and the great bronze bell — bigger than Greta herself — swung and boomed. Pigeons burst upward in a grey cloud, and Senator, who had waddled up unnoticed, shot out shrieking with feathers flying, nearly knocking Frau Mathilde off the step.

The herring barrel, taller than Greta's waist, lurched on the fish-market steps as its iron hoop snapped with a crack. Silver fish poured out in a slithering flood, sweeping across the Green Bridge planks. Tobias's one brown boot shot sideways and he grabbed his lamplighter's pole to keep upright, dragging Greta up by the apron strap before she fell. She scrambled onto the barrel's rim and hauled herself clear, laughing despite the fright. Senator plunged straight into the glittering river of herring, gulping down fish after fish, his orange feet slapping the wet boards. Frau Mathilde dropped to her knees, grabbed the broken hoop with both hands, and tried pushing the fish back into a heap with her boot while shouting through her ear-trumpet. Euler, skidding on both buckled shoes, caught himself against the empty barrel, snatched a chalk stub from Greta's apron pocket, and began marking the barrel lid — four fat dots, then seven careful lines joining them, muttering numbers under his breath as fish slid past his feet and Tobias braced the barrel steady with his pole.

The handcart hit a plank gap and tipped, and the huge honey crock, waist-high and heavier than it looked, rolled off and smashed open on the Honigbrücke, flooding the boards with a slow golden river. Greta tried to hop over it and her clogs sank in with a wet suck. Tobias, lugging the barrel-lid map under one arm, slipped and sat down hard, the lid gluing itself to his breeches. Senator, chasing a dribble of honey, planted both orange feet in the puddle and found he could not lift them, flapping and honking in outrage. Frau Mathilde waded in, boots squelching, and grabbed the lamplighter's pole from Tobias, wedging it under the goose's belly to pry him free. Euler hopped on one foot, trying to peel his own shoe off the planks, laughing despite himself. One by one they were levered loose, honey stretching in long amber threads, until the whole sticky crew stood free, shoes squelching, lid rescued, goose indignant but unharmed.

The smithy's fire roared under the sagging roof, taller than the children at its tallest flame. The smith, arms thick as hams, swung his hammer down on the anvil, which stood waist-high and black with soot. Four glowing iron rings and seven small hooked rods leapt and sparked beneath his blows. Greta hauled on the bellows handle, as long as her own arm, pumping until her round cheeks puffed and the coals blazed orange. Tobias braced his lamplighter's pole against the anvil's leg to stop it rocking, while Frau Mathilde pressed hot rings flat with a folded cloth to cool them, lifting her ear-trumpet now and then to catch the clang. Euler knelt on the dusty floor, ink-stained fingers threading the cooled rods through the rings, muttering numbers as he built a little clinking city. Senator strutted close, snatching up a dropped nail, until Tobias scooped him away from the sparks with one long arm. Bit by bit, hook by ring, the model city of bridges took shape, small enough to fit in a coat pocket, chiming softly as it grew.

The High Bridge trembled as a timber raft, logs lashed thick as barrels, swung wide and slammed into the waiting ferry below. The ferry lurched, its waist-high rail banging against the pilings, and the iron bridge-model skittered off the bench and bounced across the planks toward the open gunwale. Greta lunged, fingers scraping the cold iron hooks, but it slid past her grasp and tipped over the edge. Tobias dropped to his knees, swinging his lamplighter's pole out over the churning water, the brass hook catching one tiny rod just as it began to sink. He hauled it up dripping, arms shaking with the effort, and Greta grabbed his elbow to steady him. Euler clapped his ink-stained hands, laughing with relief. Then Frau Mathilde, already aboard the raft that had struck them, waved her great ear-trumpet high as the logs drifted loose from the bank. Senator ran along the shingle honking, wings flapping, as she floated away downriver toward Pillau, calling cheerful goodbyes nobody could quite catch.

A hard gust came whistling off the river and tore the great paper map straight out of the plump man's ink-stained hands. It burst into a hundred fluttering scraps, spinning and swooping under the low wooden bridge like startled moths. The plump man lunged after it, coat flapping, and fell to his knees on the shingle with a groan. The beanpole boy dropped his lamplighter's pole with a clatter and scrambled in after the pieces, hunching under the beams barely higher than his own head. The small girl dove sideways, snatching at a scrap caught on a splinter, her clogs slipping in the mud. They crawled in a line along the dark timber underbelly, grabbing and stuffing fragments into the apron pocket. Then the fat white goose came waddling through a puddle, bell jingling, and with a triumphant stretch of his orange neck hauled up the very last soggy scrap in his beak, strutting out from under the bridge as though he alone had saved the day.

The lecture hall was vast, its ceiling lost in candle-smoke shadow, and across the whole wide floorboards Euler had chalked a map taller than Tobias and wider than three tables pushed end to end. 'Walk it!' he cried, waving his ink-stained hand, and the children ran. Greta pounded across the chalk bridges in her clattering clogs, Tobias loped after with his pole swinging dangerously near the candle stands, and Senator waddled flat-necked straight through the middle, smearing a whole riverbank into grey smudge. Again and again they tried, boots sliding, skidding, scrambling back to the start, until the chalk city was nothing but fog under their feet. Euler laughed, dropped to his knees with his sleeve, and rubbed the whole sprawling map away in one great swipe. Then, slowly, he drew four fat dots and seven careful lines between them, counting on his ink-blackened fingers. 'There,' he said softly. 'Every doorway must be even, or somebody is left stranded.' Greta peered close, tracing a line with one floury finger, while Tobias leaned on his pole to watch, and Senator pecked hopefully at the last clean patch of chalk.

The meadow sloped wide and dark above the Steindamm Gate, and down below the whole lantern-lit city glittered along the river. Tobias came running with an armful of stakes, slamming them into the grass one by one with the butt of his lamplighter's pole, while Greta hauled coils of rope from her basket and stretched them taut between the pegs. 'Four knots for four dots, just like the chalk map!' she shouted, dropping to her knees to tie the first loop. Herr Euler trotted between them, counting on his ink-stained fingers, grabbing lantern after lantern from a creaking basket and hanging each one on a rope-knot until it swung and glowed like a little moon. Seven glowing lines stretched across the hillside, echoing the seven bridges below. Senator waddled importantly through the middle of it all, a loose ribbon snagged round his neck, dragging it in a long wobbling trail straight through the heart of the very first glowing line, as if signing his own name to the whole enormous diagram.
