'The Invisible Enemy '
Written by James Dewar and Stephen Grenfell

This week's story begins on a warm summer day in a small seaside resort in August 1946, when many English families were enjoying their first summer holiday since before the war. Hotels and boarding houses were full, and in the shops bells of cash registers were ringing cheerfully. But it was the telephone bell ringing in a doctor's surgery which was the first warning of the peril to health, holidays, and livelihood of the town.
