My Only Friend
S1 E4:
Anonymous, with the help of a computer hacker Conley (Dominic Monghan) and Ecklund (Michael Nyqvist), try to merge the existing evidence. In the "Deep Web" they find a trace: someone with the initials "LH" who is apparently recruiting killers via the web. Thereafter Ecklund receives news of another horrible crime in Stockholm.
