Scholar risked everything to tell Islamic State's secrets

He would wander the streets of occupied Mosul by day, chatting with shopkeepers and Islamic State fighters, visiting friends who worked at the hospital, swapping scraps of information. He grew out his hair and his beard and wore the shortened trousers required by the extremists. He forced himself to witness the beheadings and stonings, so he could hear killers call out the names of the condemned and their supposed crimes.

By night, anonymously from his darkened room, Mosul Eye told the world what was happening. If caught, he too would be killed.

But after more than three years, his double life grew too heavy to bear. He missed his name.
