The Gray Ghost was published by Harper in 2025 as the twenty-fifth entry in the Gabriel Allon series. The novel continues Silva’s exploration of the intersection between the art world and international espionage, with Allon operating in his dual role as intelligence chief and art restorer.
After twenty-five novels, the Allon series represents one of the most sustained achievements in contemporary espionage fiction — a body of work that has engaged seriously with the major geopolitical events of the twenty-first century while maintaining a consistent character at its center whose dual identity (artist and spy, creator and destroyer) gives the series its distinctive moral complexity.
The Series at Twenty-Five
Twenty-five novels over twenty-five years is a remarkable achievement of sustained quality. The Allon series has maintained critical respect while building a commercial readership that guarantees immediate bestseller status. Silva’s ability to integrate real-world events (9/11, the Iraq War, the Syrian civil war, Russian aggression, the Khashoggi assassination, COVID-era politics) into his fiction without becoming didactic is one of the series’ defining strengths.

Frequently Asked Questions
Is this the final Allon novel? As of 2025, Silva has not announced the series’ conclusion, but at twenty-five novels and with Allon aging, the series appears to be in its final phase.
Where should I start reading the series? Start with The Kill Artist (the first Allon novel) or The English Assassin (widely considered the first fully realized entry). Do not start with the later novels, as character development is cumulative.
