Because someone is watching Claire. Someone who is about to discover her murderous little hobby.

Hazel and Fox are an ordinary married couple with a baby. Except for one small thing: they're murderers. Well, they used to be. They had it all. An enviable London lifestyle, five-star travels, and plenty of bad men to rid from the world. Then Hazel got pregnant. Now, they’re just another mom-and-dad-and-baby.

And Hazel finds her new life terribly dull.

When I think about what I actually did, I feel somewhat sad that nobody will ever know about the complex operation that I undertook. Getting away with it is highly preferable, of course, but perhaps when I’m long gone, someone will open an old safe and find this confession. The public would reel.

And then happily got on with the rest of her life, never to regret a thing.
