Illegal Action (Liz Carlyle Series #3)

The fiercely intelligent, ambitious MI5 officer Liz Carlyle returns in a spy novel of arresting psychological complexity and unflagging suspense.

In the most recent installment in the Liz Carlyle series, Liz has been transferred to counter-espionage—the hub of MI5 operations during the Cold War. Her mission: protect Nikita Brunovsky, an increasingly vocal opponent of Vladimir Putin, who has been targeted for assassination and is seeking refuge in the UK. The Foreign Office is adamant about forestalling a crime that could become a full-blown international incident. So Liz goes undercover, attaching herself to Brunovsky's retinue: racing against the clock to determine who betrayed him and suddenly facing a wholly unexpected second task—unmasking a Russian operative working undercover alongside her.
