I have written four psychological thrillers for Harper Collins as Cass. The Woman Next Door was a number one iTunes bestseller and In A Cottage In A Wood was a Sunday Times and USA Today bestseller.

Gripped me from the start: Cass Green sensitively imagines your worst nightmare next door – a truly psychological thriller.
Claire Seeber

‘A creepy psychological exploration of the power of secrets to destroy your life.

The Girl on the Train meets Notes on a Scandal. I read it in one sitting, totally gripped.’
Erin Kelly

‘Twisty, tense and with a truly odious villain.’
Eva Dolan

The Woman Next Door had me gripped from first page to last – completely under the spell of prim yet twisted narrator Hester, a pensioner with an exhilaratingly pitch-black heart of darkness beneath her twinset and pearls.’
Ruth Ware, author of In a Dark Dark Wood

‘I couldn’t put it down. It gripped me from the first page. The best psychological thriller I’ve read all year.’
Suzy Greaves, editor. Psychologies magazine

‘Cass Green storms onto the crime scene with this classic and compelling psychological thriller – Hester is a gloriously dark character who held me in her grip from the first page to the last.’
Ava Marsh, author of Untouchable
