Madame Maigret's Own Case (French: L'Amie de madame Maigret) is a 1950 detective novel by Belgian writer Georges Simenon, featuring his character inspector Jules Maigret. The novel was written between December 13 and December 22, 1949 in Carmel-by-the-Sea, California.^[1] The book was published the following year by Presses de la Cité publishers.^[2]

The book was translated into English by Helen Sebba in 1959 as Madame Maigret's Own Case. The novel was also published in 1960 and in 2003 under the titles Madame Maigret's Friend and The Friend of Madame Maigret, respectively. The book was translated again in 2016 by Howard Curtis as Madame Maigret's Friend .^[3]

The first German translation by Hansjürgen Wille and Barbara Klau was published by Kiepenheuer & Witsch in 1954. A new translation by Roswitha Plancherel was published by Diogenes Verlag in 1979.^[4]

The New York Times found the novel to be "more police procedure than usual" with Inspector Maigret acting "less like a lone wolf and more like a police executive". The plot was also said to be "intricate" and "hard to follow; but... one of the better Simenons in tone and color."^[5]
