John Galsworthy 
Indian Summer of a Forsyte [EPUB ebook] 

In a short interlude after The Man of Property, Galsworthy delves into the newfound friendship between Irene and Old Jolyon Forsyte (June’s grandfather, and by now the owner of the house Soames had built). This attachment gives Old Jolyon pleasure, but exhausts his strength. He leaves Irene money in his will with Young Jolyon, his son, as trustee. In the end Old Jolyon dies under an ancient oak tree in the garden of the Robin Hill house.
