This is a firecracker of an addition to the Manchester Noir series by Joseph Knox featuring DC Aidan Waits, the flawed and disgraced antihero shunted onto the nightshifts with his partner, DI Peter 'Sutty' Sutcliffe. Aidan has been assigned, along with Sutty, to protect the infamous terminally ill serial killer dubbed The Sleepwalker, Martin Wick, in hospital, and tasked with trying to ascertain the location of the body of one of his victims, Lizzie. Several attempts on Wick's life had been made in Strangeways prison, Wick's had tried to take back his confession, claiming he could not remember what happened on the night a mother and her children were killed in their home. Wick has maintained his silence regarding Lizzie Moore, but has asked to speak to Sutty. After becoming aware that someone has breached security, a photograph of Wick eating breakfast has made the front page of a newspaper, a worried Aidan returns with Sutty only for all hell to break loose, that leaves Wick dead, an armed police guard dead, and Sutty with serious burns in intensive care.
Disturbed by Wick's last words to him, Aidan finds himself boxed in, in hock to numerous dangerous figures that threaten his life, including the manipulative Superintendent Parr, a member of the armed police team, and a man from his past. Parr has him conducting a shadow investigation to the official one run by DCI James, partnered by DC Naomi Black, a woman AIdan is immediately suspicious of, resulting in a spiky and tense relationship between the two of them. Their investigation has them looking at the original police investigation run by DI Kevin Blake, now retired who had written a book on Martin Wick, Frank Moore, now a motivational speaker, with a new family, and chasing the suspect woman with a tattooed face seen at the hospital. The past raises its head with a social worker contacting Aidan about his mother as Aidan dithers about getting in touch with his sister, Anne, and someone is setting up Aidan with every intention of bringing him down.
Knox creates a very dark and unsettling world, with Manchester's criminal underbelly laid bare, where it is often difficult to distinguish between the police and the criminals. Zain Carver, a powerful and ruthless drug dealer, has grown ever more respected running the well known club, The Light Fantastic, a man who has not forgotten or forgiven Aidan. The novel opens with Tessa Klein, and this is connected up at the end in a spectacular fashion, with those in the police hierarchy engaged in bitter political shenanigans in their efforts to avoid blame. It is the character of Aidan, whose life is hanging on by a thread and run through with a never ending and all encompassing darkness who holds centre stage in this wonderful series. This is a terrific and hugely memorable series, and this is an astounding addition, that will appeal to those who gravitate towards the darkest of crime reads, although I do suggest starting from the beginning.
