Fourth Assassin

This is the fourth Omar Yussef mystery from CWA John Creasey Dagger winner Matt Rees. When Omar Yussef travels to New York for a UN conference, he is eager to see his youngest son, Ala. But the discovery of a decapitated corpse in his son's empty apartment catapults him into a police enquiry full of contradictions. In his desperation to clear Ala's name, Omar's investigations place him at the heart of a deadly international conspiracy.
