A woman washes up on a Sussex beach, barely alive.

She’s wearing an old-fashioned dress and her hair has been hacked off.

There are signs she has been bound by her wrists and ankles.

She doesn’t know how she ended up there, or even her own name.

The police are baffled and when the doctors examine her, they make a shocking discovery: She has recently given birth.

Who is she?

And where is her baby?
