     Peter was mad on mountains. Climbing was the love of his life. Church towers, seaside cliffs, rock faces,

ice mountains, anything-"If it's there," he used to say, "then I want to climb it." So the news of his marriage

gave me a surprise. I'd never known him to take much interest in girls. Well, well, Peter was a married man!

I couldn't get over it. I wondered whether his wife would try to stop some of risky adventures.

     She was French perhaps-from that place where he usually spent his holidays. Chamonis, wasn't it? From

Chamonis he'd climbed Mont Blanc on his seventeenth birthday, and one of the Aifuilles the day after! That

was it, then, she was French from a family, most of whom like climbing. No doubt. No other explanation.

     A month later I met them both in town. Anna surprised me because she was English. She was a dancer

in the theater. "Never climbed more than sixty steps in my life," she told me. "Peter has his interests, and I've

got mine. No problems." "None at all," Peter said, smiling.

     "Where did you spend your honeymoon?" "I flew to New York to see the drake Dancers on Broadway.

A wonderful show!"

     Peter said, "I didn't want to miss the good weather. So I went to Switzerland and climbed the north face

of the Eiger with Allen Dunlop. Great fun, the Eiger. Grand place for a honeymoon! I'll show you the photos

we took one day."
