A bomb blast in a bookshop in an isolated corner of Turkey is staged to look like the work of Kurdish paramilitary group, the PKK.
It goes badly wrong for the assailants who, it turns out, are linked to the Turkish army.
But who gave the orders - and why?
Reporter Paul Henley gained exclusive access to former high ranking military officers who speak out for the first time.
They see the furore over the book shop explosion as proof that they are involved in a desperate struggle for the very future of Turkey.
And they talk of secret enemies who are ready for a fight.
It might sound like paranoia. But Turkey is a country caught between secular Europe and the political Islam of Iran.
The army sees itself as the one true defender of Western-style democracy.
Just how far is it prepared to go?
