THE SPRING PROTOCOL
Daniel S Ashcroft
Winter exposed the network. Spring hunts its masters.
Sébastien Noir has come home. The people he exposed are still at work.
In the aftermath of Winter, Europe's intelligence services face a question none can safely answer: how far were their own institutions compromised? With the usual channels under suspicion, European leaders ask Sébastien to build a small, independent unit to pursue the conspiracy's surviving architects.
From a former military base on the Spanish coast, the Special Investigations Unit follows a trail of extremist violence, drug money and companies whose respectable names conceal the movement of weapons, influence and fear. Each discovery sends the team further into the field, where a witness can vanish before protection arrives and an apparently helpful source can lead them straight into an ambush.
Across European ports, the South American jungle and the Atlantic, Sébastien and his team face enemies who can buy cooperation as easily as they can order a killing. American and Russian intelligence complicate the pursuit. In Chad, Roman Kovac makes the price of refusing him brutally personal.
At San Gabriel, Julia Hampton is trying to build a future beyond the violence that brought her into Sébastien's life. As loyalty grows between the people around her, someone inside their refuge is being forced to betray it. Sébastien knows how to recognise danger across a street. Recognising it among people he trusts may come too late.
By the time the trail reaches Noordhaven, finding the evidence is only part of the task. Getting people out alive will test every promise the new unit has made.
The Spring Protocol is the second novel in Daniel S Ashcroft's Protocol series: an atmospheric espionage thriller of covert pursuit, divided loyalties and the human cost of fighting a conspiracy that survives defeat.
