The tunnel

"Once a promising military intelligence officer, Danny Katz now uses his considerable gifts as a linguist and computer hacker in his work as a private investigator. He was once a high-functioning heroin addict, but his habit finally tripped him up and now he is self-employed, his relationship with his ex-wife and two daughters deeply troubled. In short, Katz is used to his fair share of suffering. But when his former drug dealer, Ramón, disappears along with Ramón's girlfriend, Jenny, the line between his current and former lives begins to blur. Many questions trail in the wake of the couple's disappearance: How did a small-time dealer like Ramón suddenly find himself in possession of a gigantic shipment of drugs? And was Jenny really who she claimed to be? Katz's investigation leads him to the darkest corners of Stockholm's black market, including its lucrative porn industry, and before long he finds his old addiction threatening to reassert its grip on his life. As the unorthodox investigation unfolds, one thing becomes clear--someone is willing to do whatever it takes to keep Katz from discovering the brutal truth. Will Katz be able to master his personal demons and find Ramón before Stockholm's netherworld once again claims him as its own?"--
