My critical View On The Sense of an Ending.

The book is written into two parts. The novel deals with flashback technique. Tony Webster nostalgic for his past in which he met Adrian and Veronica.So the game between past and present is ruuning throghtout the novel. 

one of the example from the Hollywood movie “X-Men: Days of Future Past” in which we can see the narrative technique of past and present as well.

The Ending seems to be that of the old man Anthony Webster who is near the ‘end’ of his journey of life. He ponders – feels nostalgic about the ‘past’same way In ernest Hemingway's “ old man and the sea”. In this novel also we can see the struggle of an old man man with his day to day life.Old man believed as a ‘ Laughing stock’ in his community. old man this line shows his real struggle with his life

“Because I love you, i have to kill you” Fish he said softly aloud “ i will stay with you until i am dead.” 
The Money which was given by Adrian’s mother for veronica , she said it was as a ‘Blood Money’.

Here, the puzzle isn't clear that whose baby that was? At some extant writer creates curiosity to the readers about the Baby it may be like this.
  S-V2 + A2 =B
A2 + V + a1 x S = B

B=baby(Adrian)
S=Sarah
A=Adrian(Father)
V=veronica.
S – V means that there is no good relation between mother Sarah ford and daughter Veronica. The result of their relation.

Therefore I want to conclude that with this question to answer that what is unreliable narrator? We can say that Tony is unreliable narrator because he talk about his memory and memory are not always trustworthy sometimes it is not true. So we can say that we can't rely on history.

So this is my interpretation of this text.
