"They Have Tennis Rackets" is a short story written by American author, Jean Rhys. The story was first published in 1928 and is a part of Rhys' collection of stories, "The Left Bank and Other Stories." The story is set in Paris and follows the life of a young woman named Marya who is struggling to make ends meet.

Marya is a struggling artist who lives in a small apartment in Paris. She is in a relationship with a man named Max who is also an artist. However, Max is not very successful and is often out of work. Marya is the one who supports the two of them by working as a model for artists.

One day, Marya and Max are invited to a party by their friend, Madame Fisher. At the party, they meet a wealthy couple, the Heidlers. The Heidlers are a glamorous couple who are known for their love of tennis. They invite Marya and Max to come to their villa in the countryside for a weekend of tennis and relaxation.

Marya is excited about the invitation and sees it as an opportunity to escape her life in Paris for a little while. However, Max is not as enthusiastic. He is jealous of the Heidlers' wealth and success and feels inferior to them.

When they arrive at the villa, Marya is enchanted by the beautiful surroundings and the luxurious lifestyle of the Heidlers. She is also impressed by their tennis skills and their collection of tennis rackets. Max, on the other hand, becomes increasingly bitter and resentful. He feels even more inferior when he sees the Heidlers' tennis court and their expensive tennis outfits.

As the weekend progresses, Marya becomes more and more drawn to the Heidlers' lifestyle. She begins to see it as a way out of her own struggles and poverty. Max, however, becomes more and more resentful and angry. He feels that the Heidlers are mocking him and his lack of success.

In the end, the tension between Marya and Max comes to a head. Max accuses Marya of wanting to be like the Heidlers and of being ashamed of their own poverty. Marya, in turn, accuses Max of being jealous and bitter. The argument ends with Marya storming out of the villa and Max staying behind to play tennis with the Heidlers.

"They Have Tennis Rackets" is a story about the struggle between poverty and wealth, envy and ambition. Marya is torn between her desire for a better life and her loyalty to Max. Max, on the other hand, is consumed by his own jealousy and bitterness. The story is a poignant reminder of the human desire for success and the destructive power of envy.
