with antennae and circuitry attuned to the telltale whisper of the Götterelektron. Unauthorized expression of the Willenskräfte instantly triggered the electromagnetic equivalent of a shaped charge. The British had developed a crude precursor to this technology back during the war; theyâd called their devices âpixies,â and they had a range of a few hundred meters. The Soviet fail-safes could knock out a battery at six kilometers. Klaus knew the specs because heâd helped them test the system. Heâd had no choice.
Gretel never worried about the fail-safes. Klaus stood on the cusp of fifty (according to his best estimate; he and his sister had been war orphans) and yet he still didnât know how or when Gretel called upon the Götterelektron to see the future. He suspected she relied upon batteries far less than she let their captors believe, and not when they thought she was using them. It had been that way back home in Germany, too.
They eased the vault door closed after slipping inside. Klaus groped for the light switch. Sickly yellow light cascaded from the naked bulb overhead, chasing shadows past rows of cabinets and shelves. A musty smell permeated the vault; their footsteps kicked up swirls of dust. The Soviets still referred to this place, almost reverently, as ALPHA. But they came here rarely these days.
The cabinets contained papers the Soviets had obtained during their lightning-fast occupation of the old REGP, the Reichsbehörde für die Erweiterung Germanischen Potenzials; the shelves held physical artifacts from Doctor von Westarpâs farm, where the Reichsbehörde had lived and died.
Gretel and Klaus sought the batteries their captors had confiscated at the end of the war. He had managed, after months of preparation, to sneak a single battery past the Sovietsâ stringent inventory controls. But if his sister had foreseen things correctly (of which, of course, he had no doubt), they would need every millivolt they could muster on their long trek to the Paris Wall.
The rechargeable lithium-ion packs had been cutting-edge technology, decades ahead of their time in 1939. But they were blocky, bulky things, and hopelessly outdated compared to the sleek modules the Soviets had developed. Gretelâs prescience aside, it was difficult to believe the Reichsbehörde batteries had retained any charge after twenty-two years. Klaus wiped away the layer of dust and grime coating the gauges. The batteries were degraded but still serviceable. If the gauges could be trusted.
Although Klaus had suffered tremendous misgivings about Doctor von Westarpâs research, and had lost his unswerving faith in the Götterelektrongruppe long before the Communistsâ master stroke, he now felt a frisson of relief and pride. German engineering. A reminder of those golden days when the world had been so much simpler, their shared destiny so much grander. Even degraded, these old batteries represented a wealth of power and opportunity. More than Klaus had known in decades.
They also found a few of the old double harnesses. Klaus and Gretel stripped to the waist. It was awkward, but they both managed to don two harnesses, one in front and one in back. When they had finished, they both carried four batteries beneath their clothes. It was very uncomfortable.
âLetâs go,â he said, taking her hand.
But Gretel said, âWait. We need something else, too.â She led him down one aisle and up another, to a shelf holding a pair of jars filled with sepia-colored solution. Beside them lay an empty rucksack.
âWhat are those for?â
The corner of Gretelâs mouth quirked up in a private little smile. âDonât worry. Iâve packed for you, too.â
Something in the way she said it dislodged a forgotten moment from the recesses of Klausâs memory. It was the day of their capture, minutes before. Heâd been away, and had rushed back to the
