Agoraphobic hacker Amy Lane is recovering from her last case when her ex-con assistant Jason Carr finds a new crime to solve - a murdered security guard at the National Museum of Wales and a stolen Impressionist painting worth millions. Ice-cold National Crime Agency investigator Frieda Haas is on the trail of the missing painting and charms Jason into following her to North Wales. He abandons Amy for new thrills, driving her to desperate measures to keep her panic under control and to stay on the track of the killer. Nothing in this case is what it seems and Amy's investigation takes her and Jason down a dangerous path - playing games with a murderer.
