Walter said: ‘Weigh the options! A scrap of paper signed by a tyrant, against a democratic parliament – which is better?’

‘The greatest power of all is God.’

Walter rolled his eyes. ‘Then God save Germany,’ he said.

The Germans had not had time to develop faith in democracy, Lloyd reflected as the argument surged back and forth between Walter and Gottfried. The Reichstag had been sovereign for only fourteen years. They had lost a war, seen their currency devalued to nothing, and suffered mass unemployment: to them, the right to vote seemed inadequate protection.

Gottfried proved immovable. At the end of lunch his position was as firm as ever. His responsibility was to protect the Catholic Church. It made Lloyd want to scream.

They returned to the opera house and the deputies took their seats in the auditorium. Lloyd and Heinrich sat in a box looking down.

Lloyd could see the Social Democratic Party members in a group on the far left. As the hour approached, he noticed Brownshirts and SS men placing themselves at the exits and around the walls in a threatening arc behind the Social Democrats. It was almost as if they planned to prevent the deputies leaving the building until they had passed the Act. Lloyd found it powerfully sinister. He wondered, with a shiver of fear, whether he, too, might find himself imprisoned here.

There was a roar of cheering and applause, and Hitler walked in, wearing a Brownshirt uniform. The Nazi deputies, most of them similarly dressed, rose to their feet in ecstasy as he mounted the rostrum. Only the Social Democrats remained seated; but Lloyd noticed that one or two looked uneasily over their shoulders at the armed guards. How could they speak and vote freely if they were nervous even about not joining in the standing ovation for their opponent?

When at last they became quiet, Hitler began to speak. He stood straight, his left arm at his side, gesturing only with his right. His voice was harsh and grating but powerful, reminding Lloyd of both a machine gun and a barking dog. His tone thrilled with feeling as he spoke of the ‘November traitors’ of 1918 who had surrendered when Germany was about to win the war. He was not pretending: Lloyd felt he sincerely believed every stupid, ignorant word he spoke.

The November traitors were a well-worn topic for Hitler, but then he took a new tack. He spoke of the churches, and the important place of the Christian religion in the German state. This was an unusual theme for him, and his words were clearly aimed at the Centre Party, whose votes would determine today’s result. He said that he saw the two main denominations, Protestant and Catholic, as the most important factors for upholding nationhood. Their rights would not be touched by the Nazi government.

Heinrich shot a triumphant look at Lloyd.

‘I’d still get it in writing, if I were you,’ Lloyd muttered.

It was two and a half hours before Hitler reached his peroration.
