to the Cottingley Fairies, a media cause célèbre of the early 1920s, centred on five photographs. The photographs, taken by two girls, Elsie Wright and Frances Griffiths, in Cottingley, West Yorkshire, supposedly showed fairies at the bottom of their garden. Conan Doyle believed the photographs were real and wrote a famous article about the incident which appeared in the November 1920 issue of the Strand Magazine. In The Case of the Missing Lady, Tommy refers to a concert at the Queen's Hall that he and Tuppence should attend. This hall, built in 1893, was destroyed in an air raid in World War II. It is most famous for being the first home of the Henry Wood Promenade Concerts. In Blindman's Buff and The Man Who Was No. 16, the Blitz Hotel is a play on words on London's Ritz Hotel. Christie uses the same location (and the same name for it) in the 1925 novel The Secret of Chimneys. In The House of Lurking Death, Lois Hargreaves admits to a habit of doodling a design of three intertwined fish. This design was used on the set of the collected works of Christie begun by William Collins in 1967 (but never completed) and this was approved by Christie in the spring of 1966 in discussions with the publishers. Although it has been stated by some that the doodle was a habit of Christie herself, the design was apparently spotted by her in the bazaars of Baalbek on a visit in the 1930s. The same design was used in the title sequence of the television series Agatha Christie's Partners in Crime (see below) and Why Didn't They Ask Evans? (1980). Film, TV or theatrical adaptations TelevisionThe Case of the Missing Lady (1950) from Partners in Crime aired as the twelfth episode in the twenty-six episode anthology series The Nash Airflyte Theater on Thursday, 7 December 1950 (possibly under the title of The Disappearance of Mrs Gordan).

In 1983, a ten-episode television adaptation called Agatha Christie's Partners in Crime was
