A translator documented through publication
Little reliable information about Singer’s personal life has been established. The sources consulted do not securely identify her dates, nationality, education or family. Publication credits provide the clearest evidence of her work, without establishing a connection to other people of the same name.
Her English version of Perutz’s 1923 novel Der Meister des Jüngsten Tages appeared from Elkin Mathews and Marrot in London in 1929. The held 1930 American edition was issued by Charles Boni Paper Books in New York, with an introduction by Fritz Wittels. Its title page explicitly names Singer as the translator from German.
The Encyclopedia of Science Fiction also lists Singer as translator of Perutz’s Where Will You Fall?, published in London in 1930. That credit extends the bibliographical record of her work with Perutz; it supplies no further personal history.
The English narrative and its framing
The Master of the Day of Judgment opens with Baron von Yosch insisting that he has told the truth about events in Vienna. He remembers a letter, a rain shower and newspaper reports with apparent precision, yet admits that his recollection of the time elapsed is wrong. In Singer’s English, repeated assurances of accuracy sit beside those small failures of memory.
A chamber-music gathering becomes entangled with an actor’s death, a former love affair and suspicion directed at the baron. The story reaches into an older account of artistic vision and judgment, then returns to the problem of how a written recollection can explain or conceal responsibility. Its concluding editorial postscript is part of Perutz’s fictional construction.
