The torturer should still be in prison, turns out. He got 40 years, let out early to meet CM & kill his kid.
The people who treated him said he’d move on to killing. Presumably CM is only alive by mistake; he tried to stop the ambulance reaching her after he threw her out of the window.
Marten’s interesting, but only cos you wonder how a human can turn so twisted and stay sane. She’ll be out in a few years.
Massive well done to SS for saving the other four children.
