Mörkertal Hidden Numbers

Intercrime #8

On a fresh summer’s day in the deep forests of the far Swedish north, fourteen-year-old Emily disappears without a trace. She was there on a school trip, and there are enough alarming signs for the A Unit to be called in. Meanwhile, a shocking discovery is made in a hole in the ground in the Old Town of Stockholm. On a park bench in another part of the city a man’s throat is slit. The three events seem to be connected, and the tracks lead to a network of human perversions, reaching both far back in history and out into the world via the Internet. And young Emily seems to have a closet bursting with skeletons.

Hidden Numbers is the eighth installment in the Intercrime series.
