A Quiet Drink is the third novel by the English author Deborah Moggach, first published in 1980.

Unlike her previous novels it departs from the autobiographical.

[1] The book is set in London and concerns Claudia, a magazine editor whose husband has just left her, Steve Mullen, a cosmetics representative, and his wife June.

Steve is realising his marriage to June is beginning to lose its sparkle, while June has given up her job and is spending time at the library trying to educate herself.

Eventually Steve and Claudia meet and go for "a quiet drink" which has far-reaching consequences.
