An Odd Revenge. The Oddball Odyssey, #4

People are disappearing. Important people. People with momentous, far-reaching secrets to hide. And Oddball's team are tasked with getting to the bottom of it - quick, before it escalates. Meanwhile, ordinary folk are being robbed of tens of thousands of pounds in a scam of epic proportions. The team are hard pushed to find solutions to either problem. It becomes even more urgent when Yulia Volkov, Oddball's secret lover and illegitimate daughter of the Russian president, is abducted.
Now, Russia is involved, and they're far from happy. The group are beating their heads against a brick wall until, that is, their colleague and friend Harry Lewis makes a breakthrough. Harry - real name Harriet - is feisty, acerbic, quarrelsome, but probably the best hacker on the planet. A computer genius of unparalleled skill, Harry doesn't care about high-flying politicians or religious leaders, but if there's one thing she hates, it's somebody trampling over the little people.
So when poor old Tommy Dodd has his whole identity wiped out from the system because he didn't play along with the Code Black scammers, Harry takes action. And that's when she, herself, becomes the next victim of Shadow Strategy - the terrifying scheme to kidnap people and learn their closely-guarded secrets. Oddball and the team struggle to trace Harry's whereabouts, but get one small break from a petty thief who goes a step too far.
In a race to find her in time they could never have prepared themselves for the ghastly situation they discover inside a foreign embassy.
