# The Adventure of the Illustrious Client

"The Adventure of the Illustrious Client" (1924) is one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle, and one of the 12 stories collected as The Case-Book of Sherlock Holmes (1927). It was first published in Collier's in the United States in November 1924, and in The Strand Magazine in the United Kingdom in two parts, in February and March 1925.

## Plot

Sir James Damery comes to see Holmes and Watson about his illustrious client's problem (the client's identity is never revealed to the reader, although Watson finds out at the end of the story; it is heavily implied to be King Edward VII). General de Merville's young daughter Violet has fallen in love with the roguish and sadistic Austrian Baron Adelbert Gruner, who Damery and Holmes are convinced is a shameless philanderer and a murderer. His victim was his last wife, of whose murder he was acquitted owing to a legal technicality and a witness's untimely death. She met her end in the Splügen Pass. Holmes also finds out that the Baron has expensive tastes and is a collector and a recognised authority on Chinese pottery.
Holmes's first step is to see Gruner, who is amused to see Holmes trying to "play a hand with no cards in it". The Baron will not be moved and claims that his charm is more potent than even a post-hypnotic suggestion in conditioning Violet's mind to reject anything bad that might be said about him. Gruner tells the story of Le Brun, a French agent who was crippled for life after being beaten by thugs after making similar inquiries into the Baron's personal business.
Holmes gets some help with his mission in the form of Shinwell Johnson, a former criminal who now acts as an informer for Holmes in London's underworld. Johnson rakes up Miss Kitty Winter, the Baron's last mistress, who was left permanently disfigured by him. She is bent on revenge, and will do anything to help Holmes. Kitty tells Holmes that the Baron "collects women" and chronicles his conquests in a book. Holmes realises that this book, written in Gruner's own hand, is the key to curing Violet of her devotion to the scoundrel. Kitty tells Holmes that this book is kept in the Baron's study.
First, Holmes goes to see Violet, bringing Kitty with him, but Violet is proof against Holmes's words. Kitty then makes it clear that Violet might end up ruined, or murdered, by Gruner if she continues. Violet still stands firm, and the meeting ends with Holmes narrowly averting a public scene involving the enraged Kitty.
Later, Holmes is attacked by two of Gruner's men, and the newspapers imply that he is near death. Watson goes to 221B Baker Street, only to discover that Holmes's injuries have been exaggerated to give the impression that he will be out of action for quite a while. Several days later, Holmes is sufficiently recovered to be out of bed. The Baron is planning a trip to the United States just before the wedding, and will be leaving in three days. Holmes knows that Gruner will take his incriminating book with him, never daring to leave it behind in his study.
Holmes orders Watson to learn everything that he can about Chinese pottery in the next 24 hours. The next day, Holmes presents Watson with a fake business card styling him as "Dr. Hill Barton" and an actual piece of Ming pottery, a saucer. He is to go to Baron Gruner's house, pose as a connoisseur of Chinese pottery, and try to sell the saucer. Watson does as Holmes tells him, but cannot fool the Baron for very long, and Gruner soon realises who has sent him.
As Watson faces his murderous captor, a noise from another room alerts the Baron, and he rushes into his study just in time to see Holmes jump out of the window, having stolen the book. The Baron rushes to the window, but Kitty Winter, who has been hiding outside, throws oil of vitriol in his face. Watson applies treatment to his injuries until further assistance comes.
The Baron is now hideously disfigured, but Holmes says this would not break Violet's attachment. When Violet sees the book of conquests, written in her fiancé's handwriting, she is forced to admit she has been wrong. An announcement in The Morning Post reports the engagement has been called off, and also that vitriol-throwing charges are being pressed against Kitty Winter. Extenuating circumstances reduce her sentence to the lowest possible for such an offence.

## Adaptations
### Radio and audio dramas

The story was adapted by Edith Meiser as an episode of the American radio series The Adventures of Sherlock Holmes. The episode aired on 23 February 1931, with Richard Gordon as Sherlock Holmes and Leigh Lovell as Dr. Watson. Other dramatisations of the story, likely with the same script or a slightly altered script, also aired in the same series on 8 March 1933 (again with Gordon and Lovell) and 18 April 1936 (with Gordon as Holmes and Harry West as Watson).
Meiser also adapted the story as an episode of the American radio series The New Adventures of Sherlock Holmes that aired on 5 October 1941 (with Basil Rathbone as Holmes and Nigel Bruce as Watson). Another episode adapted from the story aired on 9 May 1948 (with John Stanley as Holmes and Alfred Shirley as Watson).
A radio adaptation aired in 1960 on the BBC Light Programme, as part of the 1952–1969 radio series starring Carleton Hobbs as Holmes and Norman Shelley as Watson. It was adapted by Michael Hardwick.
An audio drama based on the story, starring Robert Hardy as Holmes and Nigel Stock as Watson, was released on LP record in 1971. It was dramatised and produced by Michael Hardwick (who also adapted the 1960 BBC radio version of the same story) and Mollie Hardwick.
"The Illustrious Client" was dramatised for BBC Radio 4 in 1994 by Bert Coules as part of the 1989–1998 radio series starring Clive Merrison as Holmes and Michael Williams as Watson, featuring Michael Feast as Baron Gruner and Ruth Gemmell as Violet de Merville.
In 2010, the story was adapted for radio as part of The Classic Adventures of Sherlock Holmes, a series on the American radio show Imagination Theatre, with John Patrick Lowrie as Holmes and Lawrence Albert as Watson.
In 2023, the podcast Sherlock&Co adapted the story in a three-episodes adventure called "The Illustrious Client", starring Paul Waggot as Watson and Harry Attwell as Sherlock.

### Television

The story was adapted in 1965 for an episode of Sherlock Holmes, starring Douglas Wilmer as Holmes, Nigel Stock as Watson, Peter Wyngarde as Baron Grüner and Rosemary Leach as Kitty Winter.
The 1991 Granada TV version with Jeremy Brett is faithful to the original, except that it shows that Miss Winter's revenge attempt on the Baron was because he had disfigured her neck and chest with oil of vitriol, and in the small detail that Grüner finds Holmes inside the house, and Kitty (played by Kim Thomson) rushes inside and past Holmes to throw the vitriol at Grüner played by Anthony Valentine.
In Elementary's third season, Kitty Winter (Ophelia Lovibond) and Adelbert Gruner (Stuart Townsend) are introduced in a mid-season story arc that changes Gruner from a philanderer and a baron to a corporate vice president and serial rapist-murderer. Kitty escaped from his captivity before he was able to kill her. She spends the first half of the season training under Holmes as a detective. When Gruner arrives in New York, she exposes his identity. Violet de Merville is a supporting character, the sister of another suspect who has no connection to Gruner. In this version, Kitty flees the United States to an unstated destination so as to escape arrest after she scarred Gruner's face with a caustic chemical. In a later episode, The View From Olympus, Holmes mentions a previous case about a man who killed his wife on the Splügen Pass and made her murder look like an accident.
