In the novel Death in the Clouds, Monsieur Georges is a hairdresser employed at Monsieur Antoine's hairdressing establishment in Bruton Street where Jane Grey also works as a hairdressing assistant.
In a two stage process, customers who came were prepared first by the assistants such as Jane or Gladys before being attended to by the hairdressers such as Georges or Monsieur Henri. In one case, Jane helps a henna-haired woman with a choice of shampoo/set or tint before Georges takes over.
