The Thénardiers are featured in the musical based on Hugo's novel. They own an inn in the town of Montfermeil, where they have been entrusted with the care of Cosette, Fantine's daughter. However, the Thénardiers treat Cosette as a servant whilst pampering their own daughter Éponine. They welcome all customers to their inn, but whilst they appear to look friendly and welcoming, they secretly con their customers with watered-down wine, sausages made with horse kidney or cat liver, and extra fees for ridiculous things such as lice, looking in their mirrors, and keeping their windows closed. ("Master of the House"). One night after sending Cosette out to draw water from the well, she returns to them in the company of Valjean. Valjean tells them of Fantine's passing and initially requests to take Cosette with him, but the Thénardiers attempt to con Valjean, deceivingly claiming they love Cosette as if she was their own daughter, have had to purchase expensive medicine to treat her for frequent illness, and are worried about the treacherous people she may encounter in the outside world ("The Thénardier Waltz of Treachery"). In the end, Valjean offers 1500 francs to take Cosette, and delighted with the money, the Thénardiers hand her over without question.
