Clarke emigrated to Ceylon (now Sri Lanka) in 1956, to pursue his interest in scuba diving. That year, he discovered the underwater ruins of the ancient original Koneswaram Temple in Trincomalee.- The Scarlet Plague (Wikipedia)
The Scarlet Plague is a post-apocalyptic fiction novel by American writer Jack London, originally published in The London Magazine in 1912. The book was noted in 2020 as having been very similar to the COVID-19 pandemic, especially given London wrote it at a time when the world was not as quickly connected by travel as it is today. However unlike COVID-19, in this story, victims died within an hour and mortality was practically 100%.
