Published in 1910, Robert W. Chambers's 'The Green Mouse' is a whimsical supernatural tale that explores the intersection of magic, class, and romance in early 20th-century New York. The story follows a ruined gentleman who discovers his only marketable talent is sleight of hand and animal control, while a young woman from a wealthy family encounters increasingly uncanny evidence of his secret magical practice. As their worlds collide through a chance meeting in Central Park, both the magician's illusions and the boundaries between reality and impossibility begin to blur in unexpected ways.
