    1.'Blood Money' in Veronica's answer email implies It was the cash that Sarah Ford offered it to Tony where there is something hidden intention was there and as it also shows some relations like Sarah Ford  is responsible for Adrin's suicide so that’s why Veronica called Blood money.
2. The equation Means b =baby or young Adrian,
 s = Sarah,
 V= Veronica,
a= Adrian.
 b = s – v x/+ a1 means, Young Adrian,
 b is a result of Sarah's relationship with Adrian (x/+) with breaking relationship with Veronica(-).
a2 + v + a1 X s = b? a2 means Anthony \ It says relationship of Tony with Veronica, and her relationship with Adrian. And Adrian and Sarah's relationship multiplies b means gave birth to baby or young Adrian.
  
  Adrian's diary is with Sarah. Their relationship is an effect of Tony's letter. So, she willed it to Tony. But Veronica knows all the things. even she can view that the reason of young Adrian's suffering is also three of them. One thing that stood out on rereading the book is that Sarah Ford doesn't look much like Veronica. She is much taller and is facially dissimilar. She also acts differently to the rest of the Ford clan and seems to take against her own daughter.
     Adrian character is not a person to lose mental condition and felt in trauma because the way Tony portrayed his character as sharp with history knowledge and very intelligent student of college. So there is very minor chance that Finn loses his mental condition.
   I think there is one reason of Adrian's suicide is the guilt of having relationship with Sara ford and because she got pregnancy in very mature age the child is born as a deformed child and Sara has also suffer a lot. so the guilt is one of the valid reason for his suicide.
     The first thing is whatever he said is only his point of view and his way looking towards life. Second thing is we can’t remember all things which happened in our past so here we can say that memory isn't unreliable or imperfect.  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.
