In 1987 the Swedish–Hungarian biochemist George Klein travelled to Vancouver to thank Vrba; he had read the Vrba–Wetzler report in 1944 as a teenager in Budapest and escaped because of it. He wrote about the meeting in an essay, "The Ultimate Fear of the Traveler Returning from Hell", for his book Pietà (1992).. The traveller's ultimate fear, English scholar Elana Gomel wrote in 2003, was that he had seen Hell but would not be believed; in this case, the traveller knows something that "cannot be put into any human language"..
