Do you think there's anything in Sheila's behaviour to suggest she was a murderer, other than her mental illness is convenient?
The fact that she was quiet ( thinking deeply ) Her quick temper. The " hints " that she gave out which no normal person would think let alone tell.
" All people are bad and should be killed " as told to BW.
" Her boys were capable of killing her,etc."as told to her psychiatrist.
Would not these be warning signs ?
In MOST cases where mothers have killed,either their GP's or Psychiatrists have said that they didn't pose a danger. How much do these people know ? They put it down to them " not being well !!" They don't say !
