London’s Muslim Mayor is dead — and it’s up to Detective Ratso to find out why.

The politically explosive investigation puts Ratso at odds with the Met’s Counter Terrorism Command as investigators struggle to determine whether the motive is political, religious, or something else entirely.

When another prominent Muslim figure is murdered, every lead points towards extremist violence.

But soon the drug-related death of a retired London accountant in Florida and the mysterious death of a British billionaire in Spain reveal a hidden network connecting the crimes.

As Ratso works with a terrified whistleblower to uncover links between the murders, corruption, and extremist networks, the case takes a dangerous personal turn.

Now facing damaging allegations that threaten to destroy him, Ratso races to expose a conspiracy far more dangerous than the murders themselves.
