Something swept overhead with a blast and a boom which shook everything in the room. A second something followed, with a long, shrill roar. Calcifer pulsed nearly blue-black, and Sophie’s skin fizzed with the backblast from the magic.

Michael scrambled for the window. “They’re quite near!”

Sophie hobbled to the window too. The storm of magic seemed to have affected half the things in the room. The skull was yattering its jaw so hard that it was traveling round in circles. Packets were jumping. Powder was seething in jars. A book dropped heavily out of the shelves and lay open on the floor, fanning its pages back and forth. At one end of the room, scented steam boiled out of the bathroom: at the other, Howl’s guitar made out-of-tune twangings. And Calcifer whipped about harder than ever.

Michael put the skull in the sink to stop it from yattering itself onto the floor while he opened the window and craned out. Whatever was happening was maddeningly just out of sight. People in the houses opposite were at doors and windows, pointing to something more or less overhead. Sophie and Michael ran to the broom cupboard, where they seized a velvet cloak each and flung them on. Sophie got the one that turned its wearer into a red-bearded man. Now she knew why Calcifer had laughed at her in the other one. Michael was a horse. But there was no time to laugh just then. Sophie dragged the door open and sped into the street, followed by the dog-man, who seemed surprisingly calm about the whole thing. Michael trotted out after her with a clatter of non-existent hooves, leaving Calcifer whipping from blue to white behind them.

The street was full of people looking upward. No one had time to notice things like horses coming out of houses. Sophie and Michael looked too, and found a huge cloud boiling and twisting just above the chimney tops. It was black and rotating on itself violently. White flashes that were not quite like light stabbed through the murk of it. But almost as soon as Michael and Sophie arrived, the clot of magic took on the shape of a misty bundle of fighting snakes. Then it tore in two with a noise like an enormous cat fight. One part sped yowling across the roofs and out to sea, and the second went screaming after it.

Some people retreated indoors then. Sophie and Michael joined the rush of braver people down the sloping lanes to the dockside. There everyone seemed to think the best view was to be had along the curve of the harbor wall. Sophie hobbled to get out along it too, but there was no need to go beyond the shelter of the harbor master’s hut. Two clouds were hanging in the air, some way out to sea, on the other side of the harbor wall, the only two clouds in the calm blue sky. It was quite easy to see them. It was equally easy to see the dark patch of storm raging on the sea between the clouds, flinging up great, white-topped waves. There was an unfortunate ship caught in that storm. Its masts were beating back and forth. They could see spouts of water hitting it on all sides. The crew were desperately trying to take in the sails, but one at least had torn to flying gray rags.
