Extraordinary and mysterious events begin very ordinarily: journalist Larsen arrives at the home of the famous writer, Nobel laureate Znorco, to conduct an interview. The writer lives alone on an island in the Norwegian Sea. During the interview, details of Znorco’s life and work are revealed. The writer's new novel is a genuine correspondence between Znorco and his lover, who later became Larsen's wife. Several years ago, she passed away, yet letters from her continued to arrive.
