Another Good Killing — Stephen Puleston

Does any man deserve to die?
When a well-connected and wealthy banker is found dead in his luxury car in the middle of Cardiff, the motive for the crime seems clear. The killer even left a note telling the world the man deserved to die, simply for his greed.
But despite the obvious clues, seasoned detective, John Marco has his doubts that this was just a disgruntled employee. The killing was too clean, the crime scene too perfect. Marco also has a gut feeling that the family of the victim are hiding something...
And when another business executive is murdered, Marco's fears come true - there is now a serial killer to catch. An online video points to a violent anarchist group, determined to make the bankers pay for their perceived sins. But Marco doubts a ragtag bunch of anarchists would be granted breathing space in the world of the sophisticated uber rich.
As the case progresses and Marco starts piecing together the clues, things take a dramatic twist when a member of Marco's team is kidnapped. Now the killer has made things personal and Marco faces a race against time to bring the murder to justice - before it's too late...
