Some say the river drowned her. Some say it brought her back to life.

On a dark midwinter's night in an ancient inn on the Thames, the regulars are entertaining themselves by telling stories when the door bursts open and in steps an injured stranger. In his arms is the drowned corpse of a child. Hours later, the dead girl stirs, takes a breath and returns to life.

Is it a miracle? Is it magic? And who does the little girl belong to? An exquisitely crafted historical mystery brimming with folklore, suspense and romance, as well as with the urgent scientific curiosity of the Victorian age.
