After Harry discovered John Doe was the boyfriend of one of Alice’s nurses, Claire, the whole hospital came under investigation.

When Nikki found Claire, she was dead, and then Nikki herself was met with a blow to the head.

The police investigation came under added pressure when a teenager was reported missing. When a raid on a witch doctor’s house turned up nothing, the community was up in arms at what they saw as harassment. In the end, Leo found that, unknown to Pastor Lambo, the boys were killed by the church caretakers, who sold their organs for use as Muti charms. He realised that it was Dr Falase, a surgeon and prominent community spokesperson, who brought them into the country for use in her clinic as kidney donors. She had then left the boys in the care of the caretakers, who knew they wouldn’t be missed.

When the mutilated body of a young black boy was pulled out of the River Lea, Leo found himself becoming obsessed with his mission to track down the boy’s identity. In order to do so he first had to piece together the story behind the boy’s death. Was this Muti, Kindoki or the cold blooded work of a paedophile? The police were no closer to finding out what happened when a second body was pulled from the river, so Leo decided to make his own enquiries. This lead him to a West African church nearby. There, Leo saw an exorcism of a young boy who was Kindoki – possessed. The Pastor, Funmi Lambo, insisted there was no violence in his church, and that far worse would happen to the boy if he were taken to Africa for exorcism. On leaving work that night, Leo found a chilling message left for him on his car, a warning to stay away.

Harry was approached by the dead pilot’s father, Henry Markham, who was convinced that the helicopter was faulty, but that his son would take the blame.

Harry had to tell the pilot’s father that as a result of his post mortem, his son would almost certainly be blamed for the crash. Later, a body was brought into the mortuary. The coroner suspected it was a case of pilot suicide. Harry opened the body bag: it was Henry Markham.

When Leo arrived, he demanded Harry’s release, but Harry’s suspicions were realised when a government minister blamed the crash on the pilot, before a full investigation had taken place.
