At last, a real rival for Ian Rankin's Rebus

Tense and tightly plotted

This is American crime thriller writing at it's rocket-fuelled, roller-coaster best

Professional-grade actioner

Enjoyable, hard-boiled stuff, with what's probably a bad-guy first - a psychotic, foul-mouthed Welshman.

An astonishing talent

A deeply unsettling debut that asks the most terrifying question - what do you have left when you lose yourself?

A truly amazing debut. The central character, Christine, is beautifully drawn. It's hard to imagine a more compelling, believable and sympathetic portrayal of a damaged human being. I loved it from start to finish

Part-bodice-ripper, part-slasher, the book's elaborate plot moves along at a brisk clip with a nod to the likes of Sarah Waters and Peter Ackroyd

A sure-footed evocation of seamy Victorian London

A sinister picture of a country, and protagonist, on the brink of hysteria

As crowded with sensation as a Victorian parlour with furniture

A spider's web of a plot and a spine-tingling atmosphere of menace and suspense

Mesmerising, elegant and compelling

This spine-tingling novel… will certainly keep your nerves jangling

An excellent ghost story...magnificently eerie...compulsive reading

She writes with great power, authentically chilling

One of the most popular British ghost stories of modern times
