C.S. Green is a pseudonym for Sunday Times and ebook bestseller Cass Green. Her first novel in the UCIT series, SLEEP TIGHT, was published in 2021 and THE WHISPER HOUSE is the second thriller featuring Detective Rose Gifford. She lives in London and also teaches creative writing classes at City University, and writes books for children under the name Caroline Green.

'Green takes us through this twisty, tightly packed thriller with her usual panache. Her writing is exciting, often darkly humorous and honed to perfection.' My Weekly‘A fascinating, eerie, and compelling police procedural with a creepy edge, and a knockout protagonist. Procedurally very tight, so get on and get it ordered!’ Neil Lancaster‘With shades of The Sixth Sense and lead character so likable, I want to invite her round for dinner, I loved Down Among The Dead. It was twisty and dark, compelling and deeply satisfying. Loved it!’ Rachael Blok‘Dark, spooky and mysterious – another compelling case for DC Rose Gifford and a treat for fans of C.S. Green’s addictive series of novels.’ Emma Haughton‘Another gripping crime thriller with a fascinating supernatural twist’ Jane Isaac‘Where has this series been all my life? A binge-worthy police procedural with a difference. Spooky, thought-provoking and compelling. I loved it!’ Catherine Quinn'Supernatural, yet plausible fiction is incredibly difficult to get right but CS Green manages it with ease, and, with Rose, has also managed to create a credible and likeable main character. The book is beautifully paced with a gorgeous dollop of humour and although I love this series you could easily read 'Down Among the Dead' as a first introduction to the fascinating world of a very unusual police department.'
