‘ Christ.’ Jack looked away. He had expected that they might find evidence of Mayne and Stein, the two Allied officers who had entered the camp soon after its liberation and then disappeared into the forest. From talking to Hugh Frazer, he knew that they were both part of the forward reconnaissance teams searching for Nazi secrets, ostensibly looking for hidden caches of art but really seeking any form of secret weapons research: anything the Nazis might use to devastating effect in their final defence of the Reich. Now he knew that what those two officers had seen would have been their ultimate nightmare, the worst-case scenario they would have been briefed that they might find. It was human experimentation, a terrible disease being perfected. Jack felt a cold shiver down his spine. A disease that may have been spirited out of the past, a past not ancient but within living memory, then refined for use once again, a disease that could take more lives than all those snuffed out in concentration camps like this one, more than were killed in the entire Nazi rampage of murder.
Hiebermeyer continued talking. ‘That chamber was like a sort of ghastly inner sanctum. A huge U-boat battery had been installed outside to provide electricity, and it was still working after all these years. Whoever constructed that place was taking no chances and had planned for this laboratory to survive the fall of the Third Reich. And I haven’t told you the full horror of the bodies on the gurneys. Two of them were different, old cadavers that had been disinterred from somewhere else, both of them partly dissected. The heads had been removed and were sitting there upright, embedded in body liquor and looking like those ancient plastered skulls of the Neolithic, only with stainless-steel forceps clamped to them like the ones the Ahnenerbe used to carry out craniological measurements when they went on their expeditions in search of Atlantis. One of them had a hole in it where the forensics lady thinks they extracted rotting brain tissue looking for something. Putting my hand in what came out of the bodies was what really did it for me, and that’s when I threw up.’
‘So these were different from the other corpses?’ Jack persisted.
Hiebermeyer nodded, and swallowed hard. ‘Different vintage. The forensics lady thinks they must have come originally from sealed lead coffins. She could even work out the year of death, because she returned to the chamber after we’d left to take a sample and analyse it using her portable lab within the bunker. She found enough to pin down what she’d already suspected was the cause of death, and everything fell into place. She was convinced that those two bodies were there because of what they contained. Still living within them when they’d been disinterred had been one of the deadliest viruses known to man, a virus everyone in the 1940s thought had been extinguished a generation before.’
Jack froze. The nightmare had become real. ‘You mean the Spanish influenza virus from the 1918 outbreak.’
Hiebermeyer gave Jack a grim look. ‘We can only speculate on what was going on here, but the forensics lady and her team are convinced. They think it was refinement, a process of trial and error, mutating and selecting the virus according to its effect on the victims, finding the most lethal form. The other corpses on the gurneys were young men born since 1918 who would not have had the immunity of survivors of the 1918 outbreak. Whoever was doing this was planning something even worse than the Holocaust, Jack: mass murder on a global scale, totally indiscriminate.’
‘Or planning to threaten the world with it,’ Jack murmured.
‘This was a true doomsday weapon,’ Hiebermeyer said. ‘A weapon of the apocalypse. The ultimate creation of Hitler’s madness.’
‘If it truly was Hitler who ordered it,’ Jack said, pursing his lips. ‘There were other architects of evil floating around him, others with egos that might have pushed them to create an insurance policy of their own if the whole Nazi scheme went belly-up.’
Hiebermeyer paused. ‘And now for the really bad news.’
‘It gets worse?’
‘There’s no evidence yet that the virus survives anywhere in the bunker. As you can see, every precaution is being taken. But there’s a downside to that. A horrible downside.’
Jack felt a lurch in his stomach. ‘You mean we actually wanted to find the virus. The refined virus. The weapon.’
Hiebermeyer nodded. ‘There was a refrigerator safe in the laboratory, about the size of a microwave oven. The forensics team are certain that’s where the result of all this horror was stored. The safe was open, Jack. There was a stand for some sort of small container like a test tube inside, and it was gone.’
‘ Jesus.’
‘Someone must have taken it back in 1945. The SS man tangled up with Mayne was dressed in camp inmate clothing, as if he were in disguise, like the SS who tried to flee from Belsen and other camps that way. He may have been lurking near the bunker to keep prying eyes out, waiting for instructions. There may have been another with him, someone who got into that refrigerator and removed it.’
‘If they were planning to take it anywhere more secure in those final weeks of the war, it would have to be towards the shrinking Nazi perimeter around Berlin.’
Hiebermeyer peered at him. ‘That’s the real reason I wanted you in Germany.’
Jack raised his eyebrows. ‘Berlin?’
‘I have an old friend who spends his free time with the Berlin Second World War archaeology group, exploring underground bunkers and tunnels of the Second World War in Berlin. When I knew I was coming to Germany, I called him on the off-chance. He told me about something they’d found just south of the Tiergarten at the site of one of the biggest bunkers of them all, the Zoo flak tower. I said I’d try to get there after this. And now because of something else we found in the bunker this morning, it’s become imperative.’
‘Go on.’
‘My friend in Berlin discovered a buried corridor that had once been under the tower. He found a door with a symbol deeply impressed in it, a reverse swastika within a roundel. And there’s something about the bunker I haven’t told you yet. Major Penn’s men also found a reverse swastika impressed within a roundel, concealed under a sliding panel on the door into the laboratory. Penn measured the impression of the swastika in the straw in the crate full of Schliemann’s treasures. It was the same dimensions and shape as the swastika in the door. And there’s more. The lock was embedded with a strong magnetic device, producing a very unusual signature. We think the palladion was magnetic; the ancient Trojan story that it had fallen from heaven, a meteorite? Whoever opened up that chamber of horrors used the sacred symbol of ancient Troy as a magnetic key.’
