I twisted my memory hard and let it spring back and I got "Inversh ... bosh ..." Bosh, indeed! Bosh and inverse bosh to all boozers, Russki or otherwise.
So I quick tried the memory trick again and this time I got "glovsh" and then I grasped and almost sneezed on diamond dust as I watched the pieces fit themselves together in my mind like a speeded-up movie reel.
It all hung on that black right-hand hussar's glove Lili had produced for Bruce. Only she couldn't have found it in Stores, because we'd searched every fractional pigeonhole later on and there hadn't been any gloves there, not even the left-hand mate there would have been. Also, Bruce had had two left-hand gloves to start with, and we had been through the whole Place with a fine-tooth comb, and there had been only the two black gloves on the floor where Bruce had kicked them off the bar—those two and those two only, the left-hand glove he'd brought from outside and the right-hand glove Lili had produced for him.
So a left-hand glove had disappeared—the last I'd seen of it, Lili had been putting it on her tray—and a right-hand glove had appeared. Which could only add up to one thing: Lili had turned the left-hand glove into an identical right. She couldn't have done it by turning it inside out the ordinary way, because the lining was different.
But as I knew only too sickeningly well, there was an extraordinary way to turn things inside out, things like human beings. You merely had to put them on the Invertor in Surgery and flick the switch for full Inversion.
Or you could flick it for partial Inversion and turn something into a perfect three-dimensional mirror image of itself, just what a right-hand glove is of a left. Rotation through the fourth dimension, the science boys call it; I've heard of it being used in surgery on the highly asymmetric Martians, and even to give a socially impeccable right hand to a man who'd lost one, by turning an amputated right arm into an amputated left.
Ordinarily, nothing but live things are ever Inverted in Surgery and you wouldn't think of doing it to an inanimate object, especially in a Place where the Doc's a drunk and the Surgery hasn't been used for hundreds of sleeps.
But when you've just fallen in love, you think of wonderful crazy things to do for people. Drunk with love, Lili had taken Bruce's extra left-hand glove into Surgery, partially Inverted it, and got a right-hand glove to give him.
What Doc had been trying to say with his "Inversh ... bosh ..." was "Invert the box," meaning we should put the bronze chest through full Inversion to get at the bomb inside to disarm it. Doc too had got the idea from Lili's trick with the glove. What an inside-out tactical atomic bomb would look like, I could not imagine and did not particularly care to see. I might have to, though, I realized.
