A young Jewish boy is brutally knocked down and scarred for life outside Ila school in Oslo. The same day, someone sets fire to the house of a prominent but controversial Norwegian politician. A mother of two is killed in the blaze. This is just the prelude to a wave of violent attacks against the Norwegian population. One thing that seems to connect these events is Norway's Middle
Eastern politics.

Axel Th. Munthe, undercover detective in Oslo police force's special operations department is brought in early in the case. Both he and the security service work hard to combat various different extremist groups, but they find themselves struggling to keep up as things escalate. Finally the threat is directed at the heart of what it is to be Norwegian: the independence day parade on Karl Johan street.

Meanwhile, Axel tries to get his regular partner Tobben back on his feet following a personal breakdown. All while the clock is ticking and the decisive hour draws nearer for Axel and the
nation of Norway.

‘Operasjon Hydra is solid literary crime writing in which the authors chase us through the pages. ... The fact that I have decided to read Mostue and Brenna’s two first novels also speaks volumes.’

‘Mostue and Brenna write well with great flow and suspense. I can’t fault them.’

MOSS AVIS

‘... the book deserves at least five out of six as it has received from most other reviewers. I look forward to a follow-up. The rest of you should keep your fingers crossed for Christmas.’
