The night ferry - Michael Robotham

Alisha Barba's dreams of being a detective were shattered when a murder suspect broke her back across a brick wall. Now on her feet again, with her police career in limbo, she receives a message from an old school friend, Cate Beaumont, who is eight months pregnant and in trouble.

On the night they arrange to meet, Cate is mown down by a car that kills her husband instantly. As paramedics fight to save her life they discover there is no baby. Her pregnancy is an elaborate lie, a cruel deception.

Why? What happened? As Alisha sets out to answer these questions she is drawn deeper and deeper into a dangerous quest that will take her from the East End of London to Amsterdam's red light district and into a murky underworld of sex trafficking, slavery and exploitation.

A gripping thriller, with twists at every turn, The Night Ferry is Michael Robotham's finest novel yet.
