Aranya and Ishan are neighbours. They are in the autumn of their lives. She is impulsive, anarchic and fiercely feminist. He is gentle, sensitive, orderly and believes in the institution of family, even though he has no one to call his own. Aranya thinks about the many Delhis, from the older one glimmering on the other side of the river to the trans-Yamuna residential complex where she lives now
 
 Ishan is deeply spiritual and draws strength from his Danish guide in the Himalayas. The two of them banter about time, existentialism, changing landscapes, food, music and human nature. They think aloud about aeging and death, and wonder living the way they do amounts to biding time.
 
Krishna Sobti's Samay Sargam is a novel about sharing solitudes and growing old in a city that is at once keenly private and aggressively collective. This is as much a portrait of the changing times as it the story of a beautiful romance that thrives on companionship.
