The Stranger Who Entered The Brownstone Without Opening The Door | A Nero Wolfe Mystery

On a bitter January night during a howling Manhattan blizzard, with every deadbolt thrown and the alarm circuit intact, Archie Goodwin returns to Nero Wolfe's West 35th Street brownstone to discover a dead stranger in evening clothes seated in the red leather armchair. The victim—a former royal Yugoslav diplomat—bears a lethal injection of rare Gaboon viper venom and a coded cipher addressed to Nero Wolfe. How did an assassin enter a sealed fortress without touching a single door? Nero Wolfe and Archie Goodwin must dismantle an impossible locked-room puzzle to recover the lost Romanov Coronation Emeralds.
