I did a Bad Thing (But Haven't We All) written by Linda Green performed by Suzy Aitchison on Cassette (Unabridged)

Now, years later, she's living a good life. She works as a local newspaper reporter and lives with her saintly boyfriend Jonathan. She has no reason to think her guilty past will ever catch up with her. Until Nick walks back into her life. And suddenly, what's good and bad aren't so clear to Sarah any more.
