St. Cross Church: where Peter marries Harriet

"Well! Last Monday evening, when we were down at Denver, we got a wire from Peter, which coolly said, "If you really want to see me married, try St Cross Church, Oxford, tomorrow at two.... We went to Oxford and found the place — an obscure little church in a side-street, very gloomy and damp-looking."
