Hazel and Fox are an ordinary married couple with a baby. Except for one small thing: they're ex-serial killers.

They had it all. An enviable London lifestyle, five-star travels, and plenty of bad men to kill. Not many power couples know how to get away with murder.

Then Hazel fell pregnant and they gave it all up for life in the suburbs; dinner parties instead of body disposal.

But recently Hazel has started to feel that itch again. When she kills someone behind Fox's back and brings the police to their door, she must do anything she can to protect her family.

This could save their marriage - unless it kills them first.
