This novel – the classic French detective story – was written in 1907 by Gaston Leroux, once a reporter who covered the famous trials of his time. (He also wrote THE PHANTOM OF THE OPERA.) Match your wits with his rival detectives – one amateur, one professional – as they try to crack the mystery. Mademoiselle Stangerson retires to bed in the Yellow Room. Suddenly revolver shots echo through the house and she screams for help. Her father and a servant run to the locked room where they find the wounded girl – alone. The only other exit, a window – barred. How had the assailant escaped?
