You kinda proved my point there.
Listening to the Big Finish Doctor Who audio The Reaping at the moment. Learning about the murder of a family friend - the father of her best friend - Peri forces the Doctor to take her back home to Baltimore, 1984. While Peri deals with "family stuff", the Doctor does a little digging and finds there's more to the murder than meets the eye. The Cybermen are in Baltimore - and whatever they're up to, Peri's loved ones are right in the middle of it.
This is pretty good so far. Col as great as ever, of course.
