A few years ago I spent an unforgettable day with Jaroslav and Alžběta Hofrichter. It was 2013, Jaroslav was 93, Alžběta 91, and they were living in sheltered accommodation for Second World War veterans at Prague’s Military Hospital. I was there to hear their life story, a tale of courage, resilience, a touch of luck and, above all, of the enduring power of love.
