W Somerset Maugham does anybody know title of?

the short story where a young man has an uous relationship with his sister but in an attempt to break it leaves on a trip to England, gets married and returns with his wife - to the dismay of his sister - and they all three live together until gradually his relationship with his sister cannot be denied and when his wife finds out there are tragic consequences. I believe Eileen Atkins feartured in a BBC production of this play - duration about 50 minutes - in the early seventies.
