Roy Grace is back in this gripping new instalment from number one bestselling author Peter James.

Brighton is celebrating. A killer is waiting. And Roy Grace is the target . . .

Brighton Pride is the biggest date on the city's calendar with half a million people lost in the party. But behind the opulent façade of the Royal Courteney Hotel, a nightmare is checking in.

Dritan Dervishi, the cold-blooded consigliere for Albanian mob boss Roel Albazi, has arrived with a beautiful woman on his arm and a lethal secret in his suitcase. He has specifically requested Room 321 - a room with a perfect view of the sea, and a deadly proximity to a target he's been dreaming of for years.

Detective Superintendent Roy Grace is already pushed to the limit, coordinating the city's massive security operation amid whispers of a potential terrorist attack. But the threat is more personal than he could ever imagine. Back in a prison cell, his old nemesis Albazi is counting down the seconds to a revenge that will not just take Roy's life, but erase his entire bloodline.

And as Roy and his wife Cleo prepare for a night of celebration at the Royal Courteney, they have no idea that they are stepping into a deadly trap.

As the relentless countdown nears zero, Roy must outsmart an invisible enemy and protect his loved ones before their time finally runs out . . .
