This looks interesting. However; I really don't think a secret agent would be allowed to tell his family about his work, and if he let something slip, I don't think his son would be broadcasting it to his friends. Chris's father is presumably with MI5 as he is dealing with national security.

If a terrorist organisation was operating in a certain area, I doubt the agent in question's family would be being moved towards the danger- the protection of civilians would be considered very important, and the government would also be aware that a secret agent's family would be in danger.

But, otherwise, this story looks interesting and I look forward to reading more of it.
