A GRIPPING TREAT FOR FANS OF SCANDANAVIAN THRILLERS

One boy is on the run from an international conspiracy . . .

Over three years ago, a civil servant vanished after returning from a work trip to Africa.

Presumed dead, his family still want answers.

It's up to Department Q, Denmark's cold cases department, to find out the truth. But what Detective Carl Morck doesn't know, is that the key to the investigation is right here in Copenhagen . . .

Fifteen-year-old Marco Jameson is tough, smart and very suspicious of police. Sleeping rough and hiding in the shadows is his way of life.

But what does he know worth killing for - and will the police find him before whoever he is running from?
