Tonight (September 25) viewers saw the death of much loved neurosurgeon Roxanna MacMillan, played by Hermione Gulliford.
Roxanna had been unable to communicate after friend and colleague John Gaskell, planned to keep her quiet after she knew the truth about his trial – she was diagnosed with lock-in-syndrome.

After being able to communicate by blinking at letters that Essie pointed to, this worried Gaskell and he put a deadly liquid in her drip which caused her death.
