MURDER DOCTRINE  A jihadist bomb brings down a massive church in Ibadan, and injured Catholic bishops flee the sanctuary-turned-death-trap...straight into the machetes of Nigeria's most fearsome terrorist group, Boko Haram. This bloodbath is only the beginning of a reign of terror linked to al Qaeda. As the gloating leader amps up the massacres of Christians across the country, Mack Bolan sets out to hunt him down and smash al Qaeda's hopes of building another major African power base.   Yet the moment Bolan hits Nigerian soil, his identity is compromised. His only allies have little training, and their priority is protecting children orphaned by the terrorists' brutal attacks. Now survival means fighting his way through the crowded city, ambush by lethal ambush, and staying one step ahead of a traitor moving in for the kill. With the death toll rising, the Executioner will have to play one last gamble to restore the region's rightful government--and send this unholy gang of jihadists into fiery oblivion.
