From Big Finish, quote;
"The Doctor and Dodo explore two contrasting eras on Earth, in stories set in modern-day Camden Town and a post-war seaside town.
2.1 The Demon Song by Bob Ayres (2 parts)
Managing to land the TARDIS in Dodo’s far flung future, the 2020s, the Doctor detects a haunting melody on the streets of Camden. People are going missing, and one of them is Dodo!
2.2 The Incherton Incident by Nicholas Briggs (4 parts)
Something intercepts the TARDIS in space. Attempting to escape its grip, the Doctor inadvertently drags it through time to coastal England in 1947. As the nation recovers from World War Two, an alien force threatens total destruction." Unquote
