“Okay. Oskar and I should be on our way to Haigerloch by then. And now comes the crucial point. It
Gisela nodded soberly.
“Okay. At ten thirty we all meet at the cave-entrance bunker. Gisela, you stay outside. We go in. You know the drill from there on.” Again he looked at Himmelmann. “Don't forget, Professor. It is important that you make certain the steel door to the reactor cave area is
Himmelmann nodded. “I understand.”
“At ten thirty-four I will set the explosives at the steel door and in the laboratory Oskar and Sig will make their way to the heavy-water storage room They will dismantle the valve and dump the borax powder into the pipe. They will reassemble the valve and get out.”
He looked at the two men.
“And remember. Leave absolutely no trace that you have been there. That is vital!”
They nodded.
“At ten thirty-nine I light the fuses.” He grinned at Sig. “Don't worry, Siggy baby, if you are not through by then — I'll wait a few seconds! Sig and Oskar will then join me and we get the hell out of there! We'll have had twenty-one minutes. We can't stretch it any further. We can expect counter-action at any time after that.
“At ten forty-one the explosions inside the cave go off. Ought to be a real ball-slammer! We need those pyrotechnics. They
He looked around at them. “If they do go ahead with the test — and I'm betting they will.” He grinned broadly.
“Good luck!”

The Luger stuck in his belt felt heavy and awkward under his coat as Dirk walked down the dark street. He felt on edge. Seeing demons in every shadow. Hearing the pounce of an ambush with every sudden sound. Ahead of him he could make out the sturdy figure of Oskar hurrying along. Behind him he was aware of Sig.
They were all intently conscious of the risk they were taking. The Gestapo scatter raids at all hours of day or night were still taking place. When the call had come they had quickly decided that the safest way to travel the night streets of Hechingen would be separately. Dirk, who had no chance of bluffing his way through an arrest, would carry the gun. If the worst happened, he would have to try to shoot his way out. With Oskar in front and Sig in the rear, they were hoping to get enough warning in case of a sudden raid for Dirk to find a hiding place. If not — he would have to use the Luger….
It was past ten thirty. Himmelmann's urgent call had come just minutes before. It was imperative that he see them at once, he had whispered on the phone, his voice harsh with anxiety. At the
They had debated what to do. They were shaken. Was it a trap? Had Himmelmann caved in? Was he betraying them? Dirk thought not. The man knew where Oskar lived. The Gestapo would have been all over the damned place if Himmelmann had talked. What, then? They had to find out. Himmelmann was crucial to the success of the raid. They had no choice but to heed his summons.
There were few people on the streets. The foreign workers, wary of the scatter raids, stuck close to their barracks. Even the native citizens were unwilling to be on the streets more than necessary.

They spotted Himmelmann sitting alone at a table in a corner. He looked nervous and edgy Casually they walked to the table and sat down.
Himmelmann did not look at the two Americans. His face had an unhealthy pallor. He talked directly to Oskar, his voice low and tense.
“Listen to me, Herr Weber,” he said “I shall talk to you only I do not wish to be seen talking to them. They must not address me Understand? Or I shall leave at once!” He glanced around the room. “I — may be watched!”
