Clouds of Witness

Clouds of Witness is a 1926 mystery novel by Dorothy L. Sayers, the second in her series featuring Lord Peter Wimsey. In the United States the novel was first published in 1927 under the title Clouds of Witnesses.
The book's title derives from Hebrews, Chapter 12 verse 1: "Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us."

In his 2017 overview of the classic crime genre, Martin Edwards suggests that Clouds of Witness is the work of a novelist learning her craft, but that it displays the storytelling qualities that soon made Sayers famous. While this early portrayal of Wimsey verges on a caricature, Sayers sought to characterise him in greater depth in later novels. Edwards notes that in this novel Wimsey is portrayed not only as a great detective but also as a man of action, and he quotes part of the defence counsel's speech to the House of Lords, explaining Wimsey's transatlantic dash to attend the trial:
"My lords, at this moment this all-important witness is cleaving the air high above the wide Atlantic. In this wintry weather he is braving a peril which would appal any heart but his own and that of the world-famous aviator whose help he has enlisted, so that no moment may be lost in freeing his noble brother from this terrible charge. My lords, the barometer is falling."
This fictional flight was written in 1926, a year before Charles Lindbergh achieved the same feat in reality (although Alcock and Brown, flying together, had crossed the Atlantic non-stop in 1919).
A copy of Clouds of Witness was one of the volumes modified by Joe Orton and Kenneth Halliwell in their adulterations of library books from the Islington and Hampstead libraries in the early 1960s.
In 1972 the novel was the subject of a BBC TV mini-series starring Ian Carmichael as Wimsey and Glyn Houston as Bunter. (wikipedia.org)
