A stranger who comes to Mary Brennan's unnamed Irish village one summer and works cutting ice creams in Lynch's grocery store. He is happy to accommodate the Lynches in any way and profits are greater than ever. They keep him on after the tourists leave and he begins spending time with Mary, a twenty-nine-year-old spinster. Louis is six years younger. Faced with her parents' opposition, Louis laments causing her more grief than happiness and wants to go away, but Mary withdraws her £1,200 fortune, quits her job, and moves with him to England, where they marry in an Italian Catholic Church. Louis convinces Mary to write only one letter home. He writes the Brennans after being diagnosed with terminal cancer, explaining that Mary is very stubborn but will need their support. He dies before an answer comes.
