Christie uses detailed imagery when describing the bedroom assigned to schoolmistress Vera Claythorne:
Vera went over to the window and sat down on the window seat. She was faintly disturbed. Everything—somehow—was a little queer [...] She got up and walked restlessly about the room. A perfect bedroom decorated throughout in the modern style. Off-white rugs on the gleaming parquet floor—faintly tinted walls—a long mirror surrounded by lights. A mantelpiece bare of ornaments save for an enormous block of white marble shaped like a bear, a piece of modern sculpture in which was inset a clock.
Unlike the more antiquated settings of many of Christie’s other novels, the house on Soldier Island has been designed “in the modern style,” a detail that becomes important as the characters attempt to identify and catch a serial killer on the island. Claythorne’s room is described with lush imagery, as the narrator notes its “off-white rugs,” the “gleaming parquet floor,” and the muted color palette. An “enormous block of white marble shaped like a bear” catches Vera’s eye due to its highly modern style. Here, Christie’s use of imagery highlights the well-lit and minimalist nature of the building and calls the reader’s attention to several details and objects that will become important later in the story.
