A real classic. A basic pillar of the how-done-it variant in mystery fiction. After reading the infinity of far-fetched solutions to impossible crimes provided by many specialists, the simplicity of the final outcome is a gratifying reading experience to the authentic conisseur. A urishing mental delicatessen. A suggestion: try to solve the candles enigma comfortably sitting in an armchair while you listen Bach's Toccata and Fugue in D mir. Good reading!
