The front room was empty, nothing amiss except the supper dishes still sitting on the table, ample witness to Opal’s unhappiness and lethargy. In Endekamene, the previous month, she would have dragged herself across the house on two broken legs rather than risk a morning visitor seeing the previous night’s crockery still unwashed, but since Flint’s disappearance and strange return his wife seemed barely able to muster the energy to do anything but sit by the child’s bedside, red-eyed.

Chert heard the dry scratching again, and this time he could tell it came from outside the front door: something or someone was trying to get in.

A thousand superstitious fears hurried through his brain as he went to where his tools were hanging on the wall and took out his sharpest pick, called a shrewsnout. Surely nothing could get through that door unless he opened it—he and Opal’s brother had worked days to shape the heavy oak, and the iron hinges were the finest product of Metal House craftsmen. He even considered going back to bed, leaving the problem for the morning, or for whatever other householder the scratching burglar might visit next, but he could not rid himself of a memory of little Beetledown, the Rooftopper who had almost died helping Chert look for Flint. The castle above was in chaos, with troops in Tolly livery ranging everywhere to search for any information about the astonishing kidnapping of Princess Briony. What if Beetledown was now the one who needed help? What if the little man was out there on Chert’s doorstep, trying desperately to make his presence known in a world of giants?

Weapon held high, Chert Blue Quartz took a breath and opened the door. It was surprisingly dark outside—a darkness he had never seen in the night streets of Funderling Town. He squeezed the handle of his pick until his palm hurt, the tool he could wield for an hour straight without a tremor now quivering as his hand shook.

“Who is there?” Chert whispered into the darkness. “Show yourself!”

Something groaned, or even growled, and for the first time the terrified Chert could see that it was not black outside because the darklights of Funderling Town had gone out, but because a huge shape was blocking his doorway, shadowing everything. He stepped back, raising the shrewsnout to strike at this monster, but missed his blow as the thing lunged through the door and knocked him sideways. Still, even though he had failed to hit it, the intruding shape collapsed in the doorway. It groaned again, and Chert raised the pick, his heart hammering with terror. A round, pale face looked up at him, grime-smeared but quite recognizable in the light that now spilled in through the doorway.

Chaven, the royal physician, lifted hands turned into filthy paws by crusted, blackened bandages. “Chert…?” he rasped. “Is that you? I’m afraid…I’m afraid I’ve left blood all over your door….”

The morning was icy, the stones of Market Square slippery. The silent people gathered outside the great Trigonate temple of Southmarch seemed a single frozen mass, packed shoulder to shoulder in front of the steps, wrapped in cloaks and blankets against the bitterly cold winds off the sea.
