Henry James 
Diary of a Man of Fifty 

Returning to Florence after 25 years of military service, a man finds himself haunted by memories of a thwarted love affair that took place on the banks of the Arno during his youth. On inquiring after the erstwhile object of his affections, he encounters a young man in amorous pursuit of her daughter. Eager to spare his young friend the sorrow that has marred his own life, the man finds himself deliberating the morality of recounting his own story. This heartbreaking tale touches on themes that were to dominate Henry James’s later fiction, including the suggestibility of youth and the dubious morality of influence. With characteristic psychological insight and a youthful fluency of expression, even in his early work James demonstrates himself a master of the art of fiction.. (Goodreads)
