St. Nicholas Wrecking and Salvage, Dana Haynes

St. Nicholas is anything but a salvage company: operating out of Cyprus ex US Marshal Michael Finnigan and former spy Katalin Fiero Dahar are bounty hunters. Their prey? The seemingly untouchable war criminals, money launderers and smugglers slimed across Europe. What Finnigan and Fiero are doing may be illegal but it's necessary.
Tasked with bringing down child traffickers preying on the caravans of Muslim refugees fleeing Syria, the duo plan to pose as buyers to draw out the ring leader but he isn't their main problem; that would be the paranoid Kosovar military commander with a unit of troops willing to die for him and an intelligence network already alerted to St Nicholas' presence.  He's decided to mount a preemptive strike on the European Courts of Justice in the Hague.
