"A man does not recover from such a devotion of the heart to such a woman! He ought not; he does not."

1913
Rosalind Spencer, the favourite daughter of Warwickshire's duke, fell in love with a gangster. Rosalind fled to Birmingham to escape the dull monotony of aristocracy and crashed into Tommy Shelby's life. They experience a summer of great love, and as Autumn comes, the pair commit to each other.
1914
Only a year after they embarked upon their journey of devotion, Gavrilo Princip ravaged their plans. A vow to wait for each other leaves their lips on a crowded station platform, but as the steam dissipates and the train leaves her view, reality and Rosalind are reunited.
1929
Rosalind Montgomery sits in a palatial library re-reading the same page of Pride and Prejudice, the particular book has been hers since she was 15 and has her maiden name of Rosalind Evangeline Constance Spencer written in the front; a telltale sign of a bygone era when she believed in soulmates and love always winning. But those dreams had left with Tommy Shelby on the train in 1914.
Tommy Shelby sits in his office, a cigarette hanging out of the corner of his mouth. A cup of tea is abandoned on his desk, the tea was his wife Lizzie's attempt to get him to drink more in the day. His desk draw is open, and a picture of a younger Tommy and a beautiful woman is gracing his palm.
Does time change anything and does love ever truly fade?
