Blegg walked in, studying that part of the reactor where steam pipes exited towards the generators next door. There—beside the pipes. No wonder the earlier searchers did not find it. The bomb appeared to be a pressure and stress analyser bolted across the point where the pipes exited the reactor. He climbed nearby steps up to a catwalk and walked along until standing beside the explosive device.

‘How long have I got?’

‘Four minutes—not long enough to deactivate it.’

Blegg considered that. Running here had been an almost instinctive reaction. He should have transferred himself through U-space to give himself more time. But, then, would another couple of minutes have made any difference? He placed his hand on the bomb. ‘A gravity switch and a timer, you say? Nothing else linked to its attachment to the pipes?’

‘So Draben just told his interrogator, and he seems less inclined to lie now. One moment. . .’ The AI fell silent for a while, then returned with, ‘It is secured by four bolts. You require a socket drive, which you will find in a toolchest below the catwalk.’

Blegg quickly returned below, found the toolchest and flipped it open. The socket driver, a gun-shaped object with a tool-head that could adjust to fit any bolt, lay amidst a well-used collection of old-style spanners. Ominous, that. He hoped whoever used the device kept it well charged and did not have to resort to the spanners too often. He picked it up and pressed the trigger -seemed okay—and returned to the catwalk. Closing the driver on the first bolt he hoped Draben was not lying. The bolt spun out easily, as did the second and third.

Placing the driver over the fourth bolt Blegg concentrated on his breathing and instilled calm within himself. The gravity switch meant he must keep the bomb to its present orientation. He clamped a hand against it and spun out the last bolt. Discarding the driver behind him, he then carefully eased the bomb away from the pipes.

‘How long?’

‘Two minutes.’

Blegg checked his watch. It would have been nice to be able to transfer himself and the device far from here, but neither gravity nor orientation applied in U-space, so such a transference might trip the switch. Amaranth would be safe; he would cease to exist. He turned slowly and walked along the catwalk to the steps, his martial training enabling him to move smoothly and evenly. Negotiating the steps was more difficult, but he reached the floor safely.

‘You need to get at least two hundred yards from the reactor,’ EC informed him. ‘Outside the door, turn to your left and keep walking. The area has been evacuated.’

The door was latched. Blegg pressed the bomb against the wall to keep it upright, opened the door and held it open with his foot as he entered the corridor beyond. His mouth dry, he continued that sliding walk.

‘How long, how far?’ he eventually asked.
