Initial reviews of the novel in 1923 were largely positive.
The New York Times said that “there seems to be no reason why the discerning, but by no means infallible, Lord Peter should not become one of the best-known and best-liked among the many amateur detectives of fiction”, while the
New York Herald called the book "The best detective story we have read since we stopped regarding books purely as amusements”. In their 1989 review of crime novels, the US writers
Barzun and Taylor called the book "a stunning first novel that disclosed the advent of a new star in the firmament, and one of the first magnitude. The episode of the
bum in the bathtub, the character (and the name) of Sir Julian Freke, the detection, and the possibilities in Peter Wimsey are so many signs of genius about to erupt. Peter alone suffers from fatuousness overdone, a period fault that Sayers soon blotted out".
A. N. Wilson, writing in 1993, noted that "The publisher made [Sayers] tone the story down, but the plot depends on Lord Peter being clever enough to spot that the body, uncircumcised, is not that of a Jew". In the 1923 text, Parker says that the body in the bath could not be Sir Reuben Levy because "Sir Reuben is a pious Jew of pious parents, and the chap in the bath obviously isn't ..." Later versions replaced this with "But as a matter of fact, the man in the bath is no more Sir Reuben Levy than
Adolf Beck, poor devil, was John Smith". In her introduction to
Hodder & Stoughton's 2016 reprint,
Laura Wilson argued that Wimsey, conceived as a caricature of the gifted amateur sleuth, owes something to
P. G. Wodehouse, whose
Bertie Wooster had made his first appearance some years earlier. Sayers said of Wimsey that "at the time I was particularly hard up and it gave me pleasure to spend his fortune for him. When I was dissatisfied with my single unfurnished room I took a luxurious flat for him in Piccadilly. ... I can heartily recommend this inexpensive way of furnishing to all who are discontented with their incomes". In his 2017 overview of the classic crime genre,
Martin Edwards said that Lord Peter Wimsey began his life as a fantasy figure, created "as a conscious act of escapism by young writer who was short of money and experiencing one unsatisfactory love affair after another". In an article in
The New York Times commemorating the novel's centenary in 2024,
Sarah Weinman wrote that “What elevated Sayers’s debut to the upper ranks of the genre was the quality of her prose and the sense that her sleuth had more emotional heft than he displayed.” She considered that even after 100 years the story remains a pure pleasure to read. ==Adaptations==
