San Francisco Night (The 6th Jack Nightingale Novel)

Jack Nightingale fights his battles in the shadows - in the grey areas where the real world meets the supernatural. But when he arrives in San Francisco to take on a group of Satanists bent on opening a doorway to Hell, the danger is out in the open and all too real. The Apostles - a Satanic coven using murder and torture to pave the way for a demon to enter the real world - realise that Nightingale is on their tail.
And unleash their own brand of monsters to take him down. With Nightingale's life - and his very soul - on the line, he has only days to stop The Apostles from bringing death and destruction to the entire world. Jack Nightingale appears in the full-length novels Nightfall, Midnight, Nightmare, Nightshade and Lastnight. He also appears in several short stories including Cursed, Still Bleeding, The Tracks and My Name Is Lydia.
