The sense of an ending

Memory is a 'lie' spoken by victors.
A person has not sure about memory is destroyed and here memory is personal opinion by Tony. It is a narrative device use memory. It is story about Tony and his school days. So memory  is personal thinking about himself.
History is something happending in Paste. Tony says his story so narrator was Tony himself so what he want to say we can only read according to him.
We think that Tony was good person. He do charitable activities in his old age. But when the letter of Tony comes in his own hand writing we come to know that how cruelly he wrote his own letter.

2)What is the meaning of phrase 'Blood money's in Veronica's reply email

In the second part when  Tony thinks that he was good person and living with satisfaction life. At that time Veronica's mother died five years ago and left him 500 pound and two documents. Now he wants to know that what is reason of Adrian's suicide and what wrote in the diary. He thinks that Adrian's diary was saved Veronica so he wants to contact to her. And why Sarah Ford leave 500 pound for Tony he wants to know so he got Veronica's E mail . He got replied from Veronica mail 'Blood money.
So Tony can't understand what is blood money. Blood money is 500 pound which sent by Sarah Ford. This is not pure money. Her relation with Adrian. And both make physical relation so Sarah Ford was pregnant and unhealthy child born and Adrian do suicide. So may be Veronica called blood money.
