‘The fourth dimension's out of joint. Oh spite That ever I was born to set it right!’

(Punch, 1919a, 442)

IN 1934 Dorothy L. Sayers paid tribute to a popular science author whom she admired very much, when she had Lord Peter Wimsey travel ‘[o]n the back of the light waves’ in solving a murder case (Sayers 1934b, 195). Her short story ‘Absolutely Elsewhere’ was published in Strand Magazine in February, having appeared across the Atlantic the previous month under the title ‘Impossible Alibi’ in Mystery, the Illustrated Detective Magazine. ‘Absolutely Elsewhere’ was subsequently broadcast by the BBC in 1940. By 1934 the trajectory of Wimsey's character development (commenced in 1920) was approaching completion and the aristocratic detective was well-known among readers of Sayers’ novels; the best-seller Five Red Herrings, also published at the start of 1934, assured her celebrity status. At the beginning of ‘Absolutely Elsewhere’ Chief Inspector Parker explains that ‘all the obvious suspects were elsewhere at the time’ (1934a, 185). Wimsey's response comes directly from Arthur Stanley Eddington's bestselling exposition of Einstein's relativity:

Sayers’ British readers would have empathized with Parker's plea for common sense to prevail over the technicalities of Einsteinian time and space. Those who had not looked at The Nature of the Physical World (1928) could scarcely have avoided all reference to this exposition, in magazines or on the radio.2 By 1934 Eddington's name had been publicly associated with that of Einstein for fifteen years, following his appearance as Einstein's champion when relativity made headline news in November 1919.
