The Eighth Sister

by Robert Dugoni

Published 9 April 2019

An Amazon Charts, Washington Post, and Wall Street Journal bestseller.

A pulse-pounding thriller of espionage, spy games, and treachery by the New York Times bestselling author of the Tracy Crosswhite Series.

Former CIA case officer Charles Jenkins is a man at a crossroads: in his early sixties, he has a family, a new baby on the way, and a security consulting business on the brink of bankruptcy. Then his former bureau chief shows up at his house with a risky new assignment: travel undercover to Moscow and locate a Russian agent believed to be killing members of a clandestine US spy cell known as the seven sisters.

Desperate for money, Jenkins agrees to the mission and heads to the Russian capital. But when he finds the mastermind agent behind the assassinations—the so-called eighth sister—she is not who or what he was led to believe. Then again, neither is anyone else in this deadly game of cat and mouse.

Pursued by a dogged Russian intelligence officer, Jenkins executes a daring escape across the Black Sea, only to find himself abandoned by the agency he serves. With his family and freedom at risk, Jenkins is in the fight of his life—against his own country.

The Last Agent

by Robert Dugoni

Published 22 September 2020

An Amazon Charts, Washington Post, and Wall Street Journal bestselling series.

An American operative in Russia is on the run for his life in a thriller of heart-stopping betrayal and international intrigue by the New York Times bestselling author of The Eighth Sister.

Betrayed by his own country and tried for treason, former spy Charles Jenkins survived an undercover Russian operation gone wrong. Exonerated, bitter, and safe, the retired family man is through with duplicitous spy games. Then he learns of a woman isolated in Moscow’s notorious Lefortovo Prison.

If it’s Paulina Ponomayova, the agent who sacrificed her life to save his, Jenkins can’t leave her behind. But there’s no guarantee it’s her. Or proof Paulina is still alive. To find out, Jenkins must return to Russia. Next move: blackmail Viktor Federov, a former Russian officer with his own ax to grind, into helping him infiltrate Lefortovo. The enemy who once pursued Jenkins across three continents is now the only man Jenkins can trust.

Every step of the way—from Moscow to Scandinavia to the open ocean—they’re hunted by a brutal Russian agent on a killer quest of his own. Out of loyalty to Paulina—dead or alive—Jenkins is putting everyone’s life on the line for a new mission that could be his last.

The Silent Sisters

by Robert Dugoni

An Amazon Charts, Washington Post, and Wall Street Journal bestselling series.

In this pulse-racing thriller by the New York Times bestselling author of The Last Agent, an American sleeper cell in Russia goes silent—and it’s one man’s duty to find them.

After a harrowing escape from Russian agents on his last mission, Charles Jenkins thinks he’s finally done with the spy game. But then the final two of the seven sisters—American assets who have been deep undercover in Russia for decades—cut off all communication with their handlers. Are they in hiding after detecting surveillance? Or have they turned and become double agents? It’s Jenkins’s duty to find out, but he’s been added to a Russian kill list. It will require all of Jenkins’s knowledge of spycraft—and an array of disguises—to return to the country undetected.

But plans go awry his first night in Moscow when Jenkins gets involved in an altercation that ends in the death of the son of one of Russia’s most powerful organized crime leaders. Pursued by mafia henchmen, Russian agents, and a particularly dogged Moscow police detective, Jenkins is determined to track down the final two sisters and get them to America—or die trying. As various forces close in, Jenkins fears this time he might’ve pushed his luck too far.
