How much the cost of this little aside, so we could dig a few holes in the Northern landscape? How many hospitals could have been built with the money? How many alms-houses? Anything worthier? Burials for dead pauper children? Gorst struggled to care, but could not quite get there. We probably could have paid the Northmen to kill Black Dow themselves and go home. But then what would I find to fill the blasted desert between getting out of bed and—

There was an orange flash, and the vague perception of things flying. He thought he saw Bayaz’ servant punch at nothing beside his master, his arm an impossible blur. A moment later Gorst’s skull was set ringing by an explosion even more colossal than usual, accompanied by a note something like the tolling of a great bell. He felt the blast ripping at his hair, stumbled to keep his balance. The servant had a ragged chunk of curved metal the size of a dinner plate in his hand. He tossed it onto the ground where it smoked gently in the grass.

Bayaz raised his brows at it. ‘A malfunction.’

The servant rubbed black dirt from his fingers. ‘The path of progress is ever a crooked one.’

Pieces of metal had been flung in all directions. A particularly large one had bounced straight through a group of labourers leaving several dead and the rest spotted with blood. Other fragments had knocked little gaps in the stunned audience, or flicked over guardsmen like skittles. A great cloud of smoke was billowing from where one of the tubes had been. A blood and dirt-streaked engineer wandered out of it, his hair on fire, walking unsteadily at a diagonal. He didn’t have any arms, and soon toppled over.

‘Ever,’ as Bayaz sank unhappily into his folding chair, ‘a crooked one.’

Some people sat blinking. Others screamed. Yet more rushed about, trying to help the many wounded. Gorst wondered whether he should do the same. But what good could I do? Boost morale with jokes? Have you heard the one about the big idiot with the stupid voice whose life was ruined in Sipani?

Denka and Saurizin were sidling towards them, black robes smudged with soot. ‘And here, the penitents,’ murmured Bayaz’ servant. ‘With your leave, I should attend to some of our business on the other side of the river. I have a feeling the Prophet’s little disciples are not idle over there.’

‘Then we cannot be idle either.’ The Magus waved his servant away with a careless hand. ‘There are more important things than pouring my tea.’

‘A very few.’ The servant gave Gorst a faint smile as he slipped away. ‘Truly, as the Kantic scriptures say, the righteous can afford no rest …’

‘Lord Bayaz, er …’ Denka looked across at Saurizin, who made a frantic get-on-with-it motion. ‘I regret to inform you that … one of the devices has exploded.’

The Magus let them stand for a moment while, out of sight, a woman shrieked like a boiling kettle. ‘Do you suppose I missed that?’
