She smiled and, for a moment, it was hard to believe she had a brother who had lived and worked in the lowest pit in hell. Blond, of course. Like she’d stepped down from the Berchtesgaden. It was easy to see where Hitler had developed his taste for blondes if he’d ever met a blonde like Helene Elisabeth von Starnberg. Either way she was a creature from another world. I might have misjudged her, but my first thought about her, that she’d never been on a tram, was not one I was able to dislodge. I tried to picture it, but the image wouldn’t stick. It always came off looking like a tiara in a biscuit tin.

“Are you any relation to Ignaz Gunther?” she asked me.

“My great-great-grandfather,” I said. “But please don’t tell anyone.”

“I won’t,” she said. “He sculpted a lot of angels, you know. Some of them are rather fine. Who knows? Maybe you’ll turn out to be our angel, Herr Gunther.”

By which I assumed she meant the von Starnberg family’s angel. Maybe it was lucky it was a fine day and I was in a good mood, but I didn’t reply with a rude remark about how, if I was going to help her brother, I’d have to be a black angel, which, of course, was what people used to call the SS. Maybe. More likely I just let that one slide by me because she was what people used to call a peach, in the days before they’d forgotten what one looked and tasted like.

“There’s a fine group of guardian angels sculpted by Ignaz Gunther in the Burgersaal,” she said, pointing across Königsplatz. “Somehow they survived the bombing. You should take a look at them sometime.”

“I’ll do that,” I said, and stepped back as she opened the door of her Porsche and climbed inside. She waved a neatly gloved hand from behind the split windshield, fired up the flat-four engine, and then sped away.
