Helen is a partner at M&L. She comes across as a highly intelligent and professional woman. She seemed off when Sonya came into the office to complain about Barry though.
Does she know about Davy Hulme Investments as well? Was she behind the attack on Sonya?
It seems weird that Helen was at Charlie's house after his father ended up in hospital. And why did she tell Jane about Charlie's drug problem? Was it to try and warn her away? Something strong is going on there.
Why is Helen having late night meetings with Peterson and hushed discussions with Karl Villiers! Is she involved in the murder somehow? She must know something - the timing of these 'meetings' is far too convenient.
Helen knew about the Cranston murder all along and was doing everything she could to keep it covered up. Karl gave her the DVD to dispose of, both of them assuming it was the only copy.
Helen had nothing to do with Rose's death but she was the reason Charlie was there that night. Suspecting that Rose had too much sway over Simon, Helen asked Charlie to follow her and find out what was going on. Even she could not have know how badly things would end that night.
