Dorothy Sayers. Clouds of Witness. (1926) Gerald, Duke of Denver, is charged with the murder of Lady Mary’s fiancee, whom he has accused of cheating at cards; that naturally means the engagement must be broken off. He refuses to provide an alibi because it would implicate a woman. Wimsey must find the additional evidence that will clear him. He does so, and delivers it just in time to warrant an acquittal.
The title alludes to the enormous amount of information that must be sifted so as to find the gaps in the evidence that Wimsey must fill. He does so with Parker’s and Bunter’s help. There’s also domestic abuse, a cabal of ineffectual lefties, a friend of Lady Mary’s whose appearance at the wrong moment leaves clues that distract, house guests that misinterpret what they see and hear, attempts to shield loved ones from mistaken suspicion, an escape from drowning in a bog, and so on. All’s well that ends well, of course.
Being a duke, Denver must be tried by his peers, in an ancient ceremony set in the House of Lords that requires a good deal of pomp and pageantry. But the evidence that will be presented, which he refuses to refute by providing his alibi, will convict him. Peter’s transatlantic flight through terrible weather succeeds just in time to rescue him.
We get more of Wimsey’s backstory, and see the first phases of Parker’s love for Lady Mary. This thread of romance the Wimsey series (taken up again in Strong Poison) has attracted criticism from readers who object that Sayers is indulging in fantasy. Maybe so, but I like it. ***
