A naked girl is washed up on London's Thames foreshore, the only clue to her identity a heart-shaped tattoo encircling two names. The sixteenth dead body recovered from the river in 2009, she is dubbed db16 by police. But who is db16? And why did she die..? Life's already complicated enough for Janusz Kiszka, unofficial fixer to East London's Polish community. What starts out as a routine missing persons job soon sees Janusz threatened by drug dealing gangsters and accused of murder by DC Natalie Kershaw, an ambitious young female detective investigating the death of db16. Janusz's search for answers takes him on a reluctant visit home to the mist-wreathed port of Gdansk, the site of traumatic memories from the Soviet era.
