Scales of Justice (novel)

Scales of Justice is a detective novel by Ngaio Marsh. it is the eighteenth novel to feature Roderick Alleyn, and was first published in 1955.

With a classic 'Golden Age' crime novel's setting, in the idyllic, self-contained, rural English community of Swevenings, the suspects are all members of a tight-knit social group revolving around the local baronet and his family, the Lacklanders.

Plot summary
The plot concerns the brutal murder of Colonel Carterette, an enthusiastic fisherman, who is preparing for publication of the deceased baronet's memoirs. The memoirs include the admission that, as a high-ranking diplomat before World War Two, the baronet had treasonably put class before country in what has been called the Herrenvolk heresy. He knowingly let a young member of the embassy staff take the blame. The young man in question, who idolised the Lacklander ambassador, had committed suicide and his eccentric father is now the murdered colonel's neighbour.

The novel represents a shift in the author's presentation of the English gentry, with whom she was on close terms from her youthful days in New Zealand, and then in 1920s London. Comparison has been made with Marsh's somewhat more deferential pre-War presentation of the English landed gentry in earlier Alleyn novel; the 1941 Surfeit of Lampreys shows a more ambivalent attitude.

Through its plot, characters and solution, the book is frankly critical of its rural gentry, their values and actions, especially in key confrontations between Lady Lacklander and the dead boy's father, and between the kindly, conservative District Nurse Kettle and the interloper revealed to be the murderer, for whom considerable reader sympathy is elicited.

Title
The method of solution of the murder revolves around the proposition that fishes' scales are individually identifiable in the same way as human fingerprints. This is behind the punning title.

Television adaptation and accusations of snobbism
This novel was adapted in 1994 for the television series The Inspector Alleyn Mysteries, with Patrick Malahide as Roderick Alleyn and, prominently among an outstanding cast, Elizabeth Spriggs as Lady Lacklander and Frances Barber as Mrs Cartarette.

It is interesting that, according to Marsh's first biographer Margaret Lewis, a proposed and abandoned 1955 BBC radio adaptation has the reader's filed note: "we should have to eliminate the appalling snobbishness". As Dr Lewis justly comments, "a truer reading of the novel would be that the appalling snobbishness is accurately depicted and firmly ridiculed by the author".
