The action of the novel takes place in the Majestic in Danemouth. I have learnt that this hotel is based on the Imperial Hotel in Torquay, Devon.
I think it is Mrs Bantry who mentions the Brighton trunk murders as some unsolved crimes. The Brighton trunk murders were two murders linked to Brighton, England, in 1934. In each, the dismembered body of a murdered woman was placed in a trunk.
Pamela, the girl who was murdered, was a girl guide. Girl Guides and Girl Scouts are a Scouting movement, originally and still largely for girls and women only across various national associations. These organisations evolved from as early as 1908, with girls wishing or demanding to take part in the then grassroots ‘Boy Scout’ Movement.
Pamela went to a girl guide rally, and then she said she was going to Woolworth’s. Woolworths Group plc was a listed British company that owned the high-street retail chain, Woolworths. It also owned other companies such as the entertainment distributor Entertainment UK, and book and resource distributor Bertram Books. The Woolworths store chain, which had more than 800 stores in the UK prior to closure, was the main enterprise of the group, selling many goods and having its own Ladybird children’s clothing range. The British branch of the F. W. Woolworth Company, which had been founded in Pennsylvania, F W Woolworth & Co, Ltd was founded by Frank Woolworth in Liverpool, England on 6 November 1909.
Miss Marple checks Mark and Josie’s marriage at Somerset House. Somerset House is a large Neoclassical building situated on the south side of the Strand in central London, overlooking the River Thames, just east of Waterloo Bridge. In 1837 the Registrar General of Births, Marriages and Deaths set up his office in the North Wing, establishing a connection that lasted for almost 150 years. This office held all Birth, Marriage and Death certificates in England and Wales.
