KADUNA, Nigeria—Some of the kidnappers were barely teenagers, shooting rifles into the air as they marched hundreds of hostages through a thorn forest to find cellphone service. They would soon relay a message to the man known as “the negotiator”—a corn farmer and part-time newspaper reporter who has become an unlikely go-between for families of the abducted and the kidnappers demanding payment.
This call was different. The kidnappers had the negotiator’s wife.
