On a cold winter's morning, the body of a young boy is discovered in Epping Forest. The body is pristine and peaceful, his head resting gently on a pillow, an angel pendant clenched in his small fist.

Nor the pregnant woman in the dental surgery. Nor the chemo patient in the supermarket for whom the cashier feels ever so sorry. They're all just alibis. In fact, the only thing that’s real about Joanne is that nobody can know who she really is.

Noticing the cable-tie restraints and the tiny scratches on Natasha’s wedding finger, Dan already knows what he will find if he looks in her mouth - the metal ball which choked her to death. Months earlier, Kim Hardy was found in the same position in a run-down hotel across the city - an identical silver ball in her throat.
