Roland Triel Crime Story #5: Exploding Vermin

A vigilante killer. A kidnapped daughter. A silent witness.
When a tied-up addict is blown to pieces in a Copenhagen apartment, Roland Triel is on the hunt for a ruthless vigilante known only as the Sweeper. The killer's identity is a secret held by only one man—a paralyzed hospital patient who must find a way to communicate his knowledge before the Sweeper returns to finish the job.
Meanwhile, Triel faces a deeply personal nightmare: his daughter has been abducted by a psychotic fugitive. With the kidnappers vanished without a trace, Triel is thrust into a desperate, off-the-books race against time to bring her home alive.
Nail-biting and emotionally charged, the fifth book in the Roland Triel series delivers another relentless dose of Scandinavian noir.
