Don't know why, but this makes me think of a book I've wanted to read but Can't Find Title. (Long ago, the NPR radio station where I lived did a "radio reader" feature which was literally someone reading a book, 30-mins. a day, beginning to end. I heard the first part of this book and then haven't been able to find/finish the story. The book was about a man who accidentally caused another man's death -- auto accident, maybe? -- and sometime later meets/falls in love with the man's widow.)
