Writing in 1936, George Orwell disagreed with the opinion of an Observer critic who felt that Gaudy Night had put Miss Sayers "definitely among the great writers". Orwell concluded, to the contrary, that "her slickness in writing has blinded many readers to the fact that her stories, considered as detective stories, are very bad ones. They lack the minimum of probability that even a detective story ought to have, and the crime is always committed in a way that is incredibly tortuous and quite uninteresting".[4]
Although no murder occurs in Gaudy Night, it includes a great deal of suspense and psychological thrills. The narrative is interwoven with a love story and an examination of women's struggles to enlarge their roles and achieve some independence within the social climate of 1930s England, and the novel has been described as "the first feminist mystery novel".[5]
Jacques Barzun stated that "Gaudy Night is a remarkable achievement. Harriet Vane and Saint-George, the undergraduate nephew of Lord Peter, help give variety, and the college setting justifies good intellectual debate. The motive is magnificently orated on by the culprit in a scene that is a striking set-piece. And though the Shrewsbury dons are sometimes hard to distinguish one from another, the College architecture is very good".[6]
Gaudy Night deals with a number of philosophical themes, such as the right relation between love and independence or between principles and personal loyalties. Susan Haack has an essay on Gaudy Night as a philosophical novel.[7]
