The Time of the Cuckoo by Arthur Laurents

Paperback / softback. New. Leona Samish, a single American woman of a "certain age" takes a long-planned European vacation from her job as a secretary and finds herself in a pensione in Venice, Italy. At a street market, she meets the handsome proprietor Renato DiRossi, entering into a casual flirtation which turns into an affair. Her complacency is jolted when she discovers he is married, has several children and is quite happy with the arrangement as is. Long-dormant frustrations and anger come to the surface as Leona faces the harsh reality of this new found infatuation and her own romantic notions of love. Shirley Booth and later Katharine Hepburn ("Summertime") played the leading role.
