A sailor is found dead on a submarine. But something doesn't add up...
Although it's ruled a suicide, Lieutenant Dani Lewis - fearless star of the Special Investigations Branch - knows the man's wife was found brutally murdered only days before. Now she must enter the cramped confines of a submarine to interrogate the tight-knit crew.

Trapped deep in the ocean - the only woman on board with a possible killer in tow - the pressure rises quickly for Dani Lewis. And she may need to choose between the truth and her own survival if she's to make it out alive. Two hundred metres below the surface, she will have nowhere to run and nowhere to hide...
