A thriller to derive reading

Polar to devour. A journalist devoured by guilt, a police inspector who doubt, potential suspects, identified a culprit, abduction of children, a group of relatives of victims lyrics run by a not always respectful of the rules shrink and ultimately for you tor, two or three nights shortened to difficulty of giving way to sleep as reading is involved. Hopefully we can take advantage of the further adventures of this cop attentive to victims. The publisher is Canadian, the Alire editions and it is not easy to find the towers books in France
