Omega Thrillers

The Omega thrillers feature Leonora, a former actress who works for the fictional Special Security Service under the codename Omega. Her ability to inhabit roles makes her an unusually effective undercover operative, but it also prevents colleagues Peter Stone and Nick Marriott from knowing which parts of her identity or loyalties are genuine.

The first novel uses bombings, drug-funded terrorism and a Surrey siege to introduce the Triple S team. The second places Omega inside an IRA cell in 1985 after Peter Stone is presumed murdered. The modern editions Operation Omega and Codename Omega are revised titles of A Woman Called Omega (1984) and The Fidelio Affair (1985), and those original titles and publication years are preserved.
