Meaning of Charlotte having Down's syndrome? Ep in old girl's school
I have just watched the brilliant episode called Nocturne, with the ghost story at the school for girls.
In the last scene, we see that the surviving girl from the 1866 killings, Charlotte, has Down's syndrome.
This seem to have some importance to Morse. Why? Would she not have inherited?
Or is it implyed that she was the killer after all?
Or is that the reason she was spared? Since she could not describe the killer? I dont know why she could not. I assume she was able to speak. I know we are told she was put in a mental home, but the killer could not be sure that she would not speak.
And, the killer killed a baby, who in any case would not have been able to say anything.
So why was she not killed? And why was it important that she had Downs?
