House of Spies was published by Harper in 2017 as a direct sequel to The Black Widow. Saladin, the ISIS operational commander who escaped at the end of the previous novel, launches a devastating attack on London. Allon pursues him through the financial networks that sustain ISIS — specifically, the connection between the hashish trade in Morocco and terrorist financing in Europe. The investigation leads through the glamorous surface of the Côte d’Azur to the criminal underworld beneath.
The novel combines two thriller modes: the hunt for a terrorist mastermind and the penetration of a criminal financial network. Silva’s Riviera — yachts, art galleries, expensive restaurants — conceals the same moral corruption that his Vatican or Moscow settings do, but with better weather.
The Drug-Terror Nexus
Silva’s depiction of the connection between Moroccan hashish trafficking and terrorist financing draws on documented intelligence about how North African drug networks funded jihadist operations in Europe. The novel’s argument — that the Côte d’Azur’s luxury economy runs on laundered money from criminal enterprises — is presented with enough specificity to feel like reportage.
Saladin
Saladin, the ISIS commander introduced in The Black Widow, is Silva’s most ambitious antagonist since the early novels. Named after the medieval Muslim leader who retook Jerusalem from the Crusaders, he represents ISIS’s ideological vision of a restored caliphate — but operates with the cold pragmatism of a military professional rather than a religious fanatic.

Frequently Asked Questions
Do I need to read The Black Widow first? Yes. House of Spies is a direct sequel, and the Saladin plot thread runs continuously from the previous novel.
