Fiona at sea. In the depths of the ocean, a criminal plan unfolds. And on board, a murderer. An engineer, found hanged in his apartment. Suicide? Another dead body, between the cliffs. Accident? That's how her colleagues see it, but Fiona Griffiths sees a trail. And it leads into the depths of the sea: a new, ultra-fast Atlantic cable – if one could siphon off data just milliseconds before the others, they would dominate every stock exchange. Whoever plans something like that will stop at nothing. Fiona narrowly escapes death and is pulled off the case. So she secretly takes a job on a trawler under a false name: as a cook. Fiona really can't cook. But she can prevent a monstrous crime in a tremendous storm.
