Doesn't anyone see,that if Bamber did kill Nevill and leave him by the Aga,then OBVIOUSLY he would have known that the police moved Nevill.so why wait 37 years before suggesting to Boyce that the Aga may have made the marks? Why not suggest the Aga made them before his trial and therefore prove that the police moved Nevill? He would most likely have been aquitted even if guilty.
The fact that JB did not mention the Aga as the possible source of the marks for all these years MUST surely prove that JB did NOT know what made the marks and did not kill Nevill and leave him against the Aga,hence if the Aga DID make the marks the only one who knew that is dead-Sheila.
So it isn't just the Aga marks for me that point to JBs innocence,its the sequence of events that has unfolded in the last 38 years.
So for me,if the Aga burns are accepted,surely logic tells us that JB must surely be innocent.
