‘We’ve been promised more magical neutralisers from your Directorate. They should help our defence.’ Saltin waved a hand at the window. ‘After all, our main protector is of Albionish design and it has been most helpful.’
‘The tower. It’s a magic neutraliser,’ Aubrey said with wonder. He could barely restrain himself from leaping out of his chair and racing out to examine it.
He had the rewarding feeling that came when a number of disparate data fell into place. The bizarre tower was a gigantic magic neutraliser. It explained the odd behaviour of the fireboat pumps, and probably explained the way the warehouse fire across the river ebbed and flowed. The warehouse must be on the edge of the neutraliser’s area of effect.
‘Grateful as we are,’ Saltin said, dragging Aubrey from his thoughts, ‘I wish your Albion thinkers had put more effort into the design. It is hideous.’
‘Isn’t that because it’s built from scrap?’ George asked.
‘We used what we had. The plans that were sent to us were deliberately flexible when it came to materials. Except from the vital parts, which were shipped to us very carefully. First to Lutetia via airship, then by train, and finally by barge to our docks.’
‘But how have you coped with no magic here, in the fortress?’ Sophie asked. ‘You’d have it embedded in a hundred little places.’
‘We do. It’s been a nightmare of plugging and patching, finding what no longer works.’ He chuckled. ‘The hot water boiler in the officer’s quarters had a magically enhanced relief valve that burst when the neutraliser began to work.’
‘Cold baths, eh, Saltin?’ George said.
‘It is a small price to pay,’ Saltin said, ‘to know that the fortress is safe from magical attack.’
‘As long at the neutraliser can cope,’ Aubrey said.
‘Do you have any reason to think it cannot?’
‘No. But I didn’t think that magic neutralisers could be built on that scale, either.’ A thought came to Aubrey. ‘That dirigible, this morning. It was trying to bomb the neutraliser?’
‘They have been trying for some time, but the tower interferes with their craft the same way as it interferes with our hot water. So far, they have missed.’
‘And managed to hit a warehouse or two,’ George pointed out.
‘Divodorum is suffering,’ Saltin agreed, ‘but we remain strong.’

While Aubrey inspected the neutralising tower under the supervision of Major Saltin, Sophie dragged George into the town on an expedition to find food. Aubrey found the construction fascinating. Four massive legs, made up of multiple steel girders bolted together, slanted up to a platform. Bracing these legs was an erratic web of timbers of all sizes, completely enclosing the interior of the area bounded by the legs. The array interlocked so completely that Aubrey suspected the whole thing had been organised by a corps of lacemakers who had grown tired of doilies and who had leaped at the chance to create something on a monumental scale.
High overhead, projecting from the lofty platform, was a metal cylinder. When Aubrey shaded his eyes, he could make out that it must be at least a foot in diameter and was solid, not a pipe, although Aubrey was prepared to wager that this was because both ends were capped and that the workings of the neutraliser were inside. He could feel the tell-tale emanations of magic that trickled from it – a passive but immensely powerful spell at work.
Both ends of the cylinder jutted out past the edges of the platform by a good three feet. Attached to each end of the cylinder was the most puzzling aspect of the entire construction: four slim metal rods, ten or fifteen feet in length, in the formation of a cross. By walking around and around the unlikely construction, Aubrey could see that the crosses were offset, not mimicking the angle of the other.
Aubrey spent some time trying to establish the extent of the magical protection afforded by the giant neutraliser. Under Major Saltin’s amused eye, he backed away from the structure, trying a simple fire spell every few yards. Eventually, he had to exit through the gatehouse. Whoever had been in charge of enspelling the central core of the machine had done a fine job – or had been extremely lucky. The neutralising field was as nearly circular as Aubrey could make out, and it cloaked the fortress completely, ending some distance outside the walls.
Aubrey looked across the river to where the fire was still alive in the warehouse. Standing where he was, he felt the way the neutralising field fluctuated, pulsing almost like a living thing. He could imagine it rippling enough to touch the fireboat, or the warehouse – but if it extended as much that way, would it also shrink enough to put the fortress in jeopardy?

Aubrey arrived back at their base just as George and Sophie rode up, laughing, but Aubrey was immediately alert when he opened the front door to find the place was empty.
‘Caroline!’ He ran to the stairs. ‘Caroline!’
‘Aubrey,’ Sophie said. George was propping their bicycles against the wall while she waited at the bench just inside the door. She lifted one of the many glue pots and extracted a sheet of paper. ‘I think this note is for you.’
I am asleep, Aubrey read with the growing knowledge that he’d leaped before he’d looked. Do not wake me. Aubrey: the orders are in the secure place.
He swallowed. ‘Was I too noisy?’
George shrugged. ‘Unless she was cocooned in about a mile of sound-deadening material, I’d say so.’
The secure place had been organised before they’d left the base for their Stalsfrieden expedition. George had managed to construct a false ventilator cowling from sheet metal, and Sophie – with Aubrey’s guidance – had used the Law of Similarity and the Law of Seeming to reinforce this camouflage. Inside were niches, shelves and boxes that were attuned via the Law of Affinity only to reveal themselves when Aubrey, George, Caroline or Sophie reached for them.
Aubrey quickly found the orders. Caroline had decoded all six pages. He hoped it hadn’t taken too long, but he knew her pride wouldn’t have let her rest until she’d completed the task.
He took the stairs to the roof and sat, cross-legged, in the late morning sun, his back to the brick-walled utilities shed, absorbed in the details of the orders, which were couched in roundabout military language but all the more startling for it.
The Directorate had been at an impasse in its plans for the Divodorum front, but now that Aubrey and his team were once again in place a vital delivery was on its way. A shipment of magic neutralisers would arrive in two days’ time, and Aubrey’s orders were to take them to the front before the Holmland assault began.
When he reached the end of the orders, he took to his feet and read them again while carefully pacing the length of the roof between the lines of antenna wire.
Some of his fears were confirmed. Magic neutralisers had no point unless magic was needing to be neutralised. The Directorate obviously was of the same mind as he was: when the Holmland assault came, it would be accompanied by magic.
Aubrey stopped, looked to the north-east from where the sound of artillery was a distant, constant punctuation, then scanned the orders again.
The Directorate’s intelligence and analysis agreed with the information Aubrey had sent. The Holmland assault would begin within a week.
