The historian carried secrets too heavy for one man to bear.

He packed his bag with his most treasured possessions before going to bed: the 1 terabyte hard drive with his evidence against the Islamic State group, an orange notebook half-filled with notes on Ottoman history, and, a keepsake, the first book from Amazon delivered to Mosul.

He passed the night in despair, imagining all the ways he could die, and the moment he would leave his mother and his city.

He had spent nearly his entire life in this home, with his five brothers and five sisters. He woke his mother in her bedroom on the ground floor.
