A standalone from the Rebus author.

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

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

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