The police surround the flat but David hands the gun over to Greg, explaining that it was his father's gun, which he had found and wanted to get rid of. Nikki is verbally abused by Charlie's father and DI Klein wants her suspended but Clarissa and Jack discover that the gun found by David did not kill Charlie and nor could he have killed Byron Lee. The pathologists work out that the real serial killer had an alarming insight into David Bennetto's background and their motive was not sexual but obsessed with having power over others. Circumstances also end Nikki's involvement with Greg Walker.
