Hornet Flight by Ken Follett 2002 Hardcover

In separate locations across the war-ravaged landscape of northern Europe in 1941, a plot is slowly being uncovered. The trouble is that no one person--a policeman in Copenhagen, a teenager on a remote island in the North Atlantic, and a British agent in London--has all the clues, and if the pieces aren't put together, and soon, Britain will likely fall to the relentless onslaught of the Third Reich.

In June 1941, with the war not going well for the British, the lives of three people on both sides of the English Channel--MI6 intelligence analyst Hermia Mount, Danish police detective and collaborator Peter Flemming, and young Harald Olufsen--intertwine as Harald makes a discovery that could change the course of the war, if he can get the information to England. Book in overall good condition.
