Description: This princess, who comes from Russian royalty, is perhaps one of the most memorable characters in the novel. Here's how Poirot first sees her: "At a small table, sitting very upright, was one of the ugliest old ladies he had ever seen. It was an ugliness of distinction — it fascinated rather than repelled. She sat very upright. Round her neck was a very large collar of pearls which, improbable though it seemed, were real. Her hands were covered with rings. Her sable coat was pushed back on her shoulders. A very small expensive black toque was hideously unbecoming to the yellow, toad-like face beneath it."
