But this property company is not what it seems. And neither is Rupert.
It is a front - for the UK's intelligence service.
When a series of deadly terror strikes begin, Rupert swings into action.
But he faces a test as challenging and deadly as any in his career.
The terror plot leads not to al-Qaeda, or any other known threat. It leads to Big Mama, a former sex worker who built up her own criminal empire in Thailand before going global.
But Big Mama is a woman with a grudge - and not just against the pimps and sex traffickers who ruined her youth.
And as Rupert is about to discover, Operation Herod is a threat to all mankind.
Operation Herod is a brilliantly fast-paced, gripping action thriller in the style of the great masters of the genre - Ian Fleming, Len Deighton and Jack Higgins.
Andrew Cartmel's roller-coaster thriller has been widely praised.
"With a luckless spy and a formidable femme fatale, Operation Herod is a bright and fast-moving entertainment of double lives and double-dealing. The spirit of the 60s espionage thriller takes on new life and vigour in the hands of Andrew Cartmel." - Stephen Gallagher
''Cartmel's writing is a Heckler & Koch automatic wrapped in expensive lingerie. Brutal, exciting, engaging and witty. In the words of a woman who knew her spies: 'Nobody does it better, makes me feel sad for the rest." - Guy Adams, best-selling author of The Change.
