The Tunnel

Inside the Channel Tunnel, on the borderline between Britain and France, the body of a woman is discovered. As the corpse is lifted it becomes clear that this is no ordinary murder. A thrilling and complex cross-Channel investigation ensues.

The killer uses the internet to very publicly announce his first 'Truth' - that we are not all equal before the law. When Karl and Elise discover that he is using British police servers to host his site, they are wrong-footed - they are obviously dealing with a criminal mastermind.

As Suze is recovering in hospital, the killer, nicknamed the "Truth Terrorist" by Hillier, calls Hillier to inform him he will continue the second truth in France, and later kidnaps a World War 2 veteran. Elise comes to understand that the Truth Terrorist is a mastermind, having covering his tracks thoroughly. What he does not account for is that a runaway teen couple accidentally find Jean-Claude, and are captured by the Truth Terrorist.

French police notice occasional vibrations on the live stream, which they determine (via audio analysis) are passing trains. They narrow his location to two cold stores. Karl and Elise search for what turns out to be the correct location. Armed police attempt to apprehend the Truth Terrorist.

The Truth Terrorist's third truth begins as Benji carries out his Samurai mission. Sophie's life is now at stake and police believe they can use her to stop TT's rampage. Karl gets more than he bargained for while visiting Charlotte.

As youths are burnt alive, police suspect the hand of the Truth Terrorist once more. They finally make a key arrest. Will this be the end of the killings in this brilliantly tense Anglo-French thriller?
