Above the bed, the four pictures on the wall show the four sisters: Ella, pointlessly petrified by the sun. Peggi, who mimicked more or less successfully the sound of a rhinoceros. Viola, a helpless little ballerina. And Olivia, who looked like a princess. She is wearing a grey cloak and a lace ruff dress with stripes, and she is posing in front of some brass plates engraved with messages about the goddess Europa.
