The Hyde Park Incident.
The Hyde Park Incident occurred on the morning of July 11, 2045, when 100-meter by 30-meter crop circle was discovered in the center of the park. The massive, mysterious installation was constructed from local grasses, gravel, and hedges, and appeared to be a permanent garden. Its presence baffled a stunned London and global audience, as officials struggled to explain its sudden appearance and the lack of witnesses at its creation. Many believed the work to be a protest act or publicity stunt, but no author ever came forward to claim responsibility. On the morning of July 13, 2045, the crop circle vanished, leaving no trace of its inexplicable presence. To this day, the creation and disappearance of the crop circle remains a mystery.
