Bob Shaw

“Light of Other Days” is a short story by Bob Shaw, published in August 1966 in Analog Science Fiction/Science Fact. A couple in crisis travels to a rural area of Scotland, where slow glass panels are manufactured — a peculiar material that delays the passage of light and captures scenes with astonishing clarity. Amid a haunting and silent landscape, they visit a remote farm and meet the eccentric maker, who offers them a high-quality panel that has been storing light for ten years. However, what initially seems like a simple commercial transaction gradually reveals a deeper and more unsettling story.
