• The "Blue Light" Spies

  This theory held that German spies in Britain used hidden blue lamps, flashes, or other coded light signals to guide Zeppelin raids to their targets. It flourished during the First World War airship raids on Britain, especially after civilians experienced bombing from the air and began to fear enemy agents already inside the country. The panic belongs to the larger phenomenon of wartime spy-fever, but gained a specific form because blackouts, vehicle lamps, service lights, and urban commotion made ordinary illumination look suspicious.
