Their new mission—to unravel the mystery of a missing policeman’s son—multiplies the dangers they face, yet Elias’s new family member just might tilt the scales in their favour…

The fourth installment of Timo Parvela’s excruciatingly thrilling series, spiced with Roald Dahl-esque humor, is an standalone adventure and puzzle.

“Parvela knows how to write engagingly for young readers who read little or avoid books. There is nothing superfluous, and the plot never stalls for a moment….…you can’t bear to put down. It would be a nearly impossible mission in itself.” – Mari Viertola, Turun Sanomat, of Mission Nearly Impossible 1
