Crazed Cathy, played by Connie Hyde, sets fire to DC Brandon Kane’s house tonight with pretty PC Honey Harman and his kids inside.

The ITV1 drama’s 10million fans will see Honey (Kim Tiddy) battling to save her boyfriend’s kids. We can reveal they fight their way to safety next week – but this isn’t the end of Cathy’s schemes.

She has already murdered DC Kane’s wife and conned fellow cops that she is HIV positive.

An insider said: “Cathy is determined to get her hands on Brandon.

“She is horrified when he offers Honey a place to stay and sets out to get rid of her.

“Evil Cathy sets Brandon’s house on fire and calmly watches from the car as it burns with Honey and his kids trapped inside.”
