Brilliant post Grahame, pure logic.

I also go along with that too,Grahame.
In March 1985 when Sheila was admitted to St Andrews Hospital,she'd suffered a severe mental breakdown. A friend was left traumatised after one of Sheila's violent outbursts.
Sheila had been taking cocaine quite frequently that year. She was released from hospital after just 3 weeks and her release raised concerns over the idea that Sheila was capable of murdering her children and had mentioned having suicidal thoughts.
I would be interested in seeing her medical records from this particular time in her life,,,and would also be interested to see who'd voiced their concerns too.
Her medication was powerful stuff,and coupled with cannabis as well as cocaine,makes for a very volatile cocktail. If anyone reads about schizophrenia and cannabis,,it'll give you the clear answer as to who was responsible for the murders and also for Sheila's own suicide.
Her medication too,is worth reading about,,,its effects and what the results are if missed or suddenly reduced ( as Dr Ferguson had done,,and is a very dangerous move as it should be reduced gradually )
Anafranil.
Haloperidol.
Procyclidine.
