Set in the secretive, opulent world of London's super-rich, Ian Rankin's first standalone thriller in two decades introduces a new female inspector.

Murder comes to London's most luxurious high-rise: and every resident is a suspect.

The Heights: a gleaming, high-end high-rise looming over Hyde Park. Newly built from steel and smoked glass, a billionaire's playground offering suites for the global elite.

But when a night concierge is found murdered in the lobby, the building's atmosphere is shattered, and the lives within come under police scrutiny.

In a world designed to keep prying eyes out, where the residents are not used to being held to account, Detective Gillian Gish must find a way past their power, wealth and influence.

The rules may be different at the top - but is anyone truly above the law? Or could it be that the higher you rise, the further you fall...?
