Do you know if any of the other books do? Not that the other books would add much as Wilkes's overview is good.
Wilkes's book also gives a good report of the judges summing up.
No not really. Carol Ann Lee's book has four chapters on the case (40-43) and at least has an index at the back, unlike
Blood Relations. Clare Powell's book has two chapters devoted to the trial, one entitled In The Dock followed by Actor or Actress? a reference to whether you believed Jeremy or Julie. Scott Lomax is the one book entirely skewed in favour of Jeremy and will have you jumping through so many hoops to make him innocent you may become dizzy.
There's more on egap1's thread on Murder/suicide at White House Farm if I can locate it here.
