Círculo del Crimen: El Misterio de la Casa Roja

The Red House Mystery by A.A. Milne This detective novel, Milne's only mystery written for his father's entertainment, is set in an English country house belonging to Mark Ablett. The household includes various guests: a British major, a stubborn actress, and a young athlete. Robert Ablett, Mark's brother and the family's "black sheep," arrives from Australia after a fifteen-year absence. He is found dead in a locked room. Mark Ablett has disappeared, prompting guests Tony Gillingham and his friend Bill to investigate playfully, accumulating clues and theories throughout. The opening chapters establish the household staff's surprise at Robert's unexpected arrival and present ominous sounds within the house—shots or explosions—that alarm the servants, particularly cook Mrs. Stevens and maid Audrey, who feared the rough colonial visitor may have brought a revolver.
