Variam disappeared quickly, probably glad to be out of the blast radius. “Right then!” Landis said. He was still holding the bomb in his left hand, and the safety cap was still off. The pressure sensor glowed menacingly; I knew it would only take a strong tap to detonate it, and I had to restrain myself from flinching as Landis waved it in my direction. “Good old Vari told me the story. Fascinating account, wish I’d seen the fellow who went after you, Verus, must have been quite the spot of exercise, hmm?”

“You could say that.”

“Wish I’d been there, but we’re still on standby. Tedious business, but ours not to reason why.” He sighed for a moment, then visibly brightened, set the bomb down on one arm of the chair, and rooted around in his pocket to produce the same focus I’d given Variam last night. “Not much to look at, is it?” he said with interest, studying the green marble. “Hidden depths, though, the data array is mightier than the sword, hmm? At least when we’re talking Council politics.”

I kept a wary eye on the bomb. Landis had balanced it on end on its fins. It would only take one jerk of the chair to knock it to the floor, in which case it had roughly a fifty-fifty chance of landing on its tip and blowing apart the chair, the benches, the floor, and probably us. “Data array?” Caldera said.

“Indeed! Good old-fashioned storage device. Lovely craftsmanship, don’t see many of them these days.” Landis studied the focus admiringly, then glanced up as Variam came back. “Ah, man of the hour! Just in the nick of time.”

Variam distributed teacups. Landis leant forward to take his, making the chair sway, and I winced. “Okay, so you’re saying . . . um . . . is there any chance you could put the cap back on that bomb?”

“Eh? Goodness, you’re right! Memory like a sieve.” Landis caught up the bomb, twirled the cap back onto it, and then threw it without looking in the direction of the sofa. Even though I knew it wasn’t going to blow up I couldn’t help but close my eyes briefly. The bomb thumped into the cushions, bounced once, and lay still. I let out a sigh of relief and shared a glance with Caldera. She looked relieved too. Variam hadn’t moved—maybe he was desensitised to it.

Landis, meanwhile, was in full cry. “. . . marvellous design! Completely stable once they’ve been set to the user, and no energy requirements at all. You see that distinctive little fractal pattern at the centre, little universal-tinged beggars? That’s the Halicarnassus influence. Tricksy things, bugger to forge but worth the effort.” He beamed at the two of us.

“So let me get this straight,” Caldera said. “It’s a data storage?”

“Right on the bull’s-eye!”

“Can you read it?”

“My dear girl, weren’t you listening? What’d be the point of a signature lock if any Tom, Dick, or Jehosaphat could come along and take a gander?”
