I loved this book when I read it. This is a second copy that my grandma had and gave to me to release.

In June 1941 a baffling Luftwaffe radio message mentioning a new invention with the codename Freya (the Viking goddess of love) is picked up by the decoders of Allied intelligence. Hermia Mount, a British intelligence analyst, suspects the existence of an experimental radar station on the coast of Denmark. Meanwhile, young Harald Olufsen, a brilliant Danish student, has spotted an unusual installation near his island home.
Unable to resist a challenge, Harald is soon drawn into Hermia's investigation, but when he finally learns the truth, he finds the only way of getting to England with the information is in a near-derelict Hornet Moth biplane, mouldering away in the nave of a ruined church...

Picked it up at Cententary Square, Birmingham city centre(UK), was a good read, as i am currently travelling in Canada(Toronto) i thought id leave it here to aid it on its journey.
