In mid-March, as the novel coronavirus spread across Europe and the U.S., Eve went with some friends to a London pub to mourn a ski trip the accelerating pandemic had canceled. They shared food and drinks, a last hurrah before the world went into lockdown.

The next day, Eve hopped on a plane to Dubai, where she stayed for a few days, then another to San Francisco. On March 28, after eating a blue cheese and truffle omelet that tasted like nothing, Eve tested positive for Covid-19. Eventually, so did most of her friends from the pub that night.
