From Netflix:

Ten years after losing two loved ones, a man is plunged into another dizzying mystery when his girlfriend vanishes. Based on a Harlan Coben novel.

From Netflix you can stream the 6 episodes, each episode less than one hour, of the serialized adaptation of Coben’s 2001 novel of the same name. French with English subtitles.

Even the reviews of Coben’s novel complain that this is not one of his better novels.  Confusing plot twists, hard to accept events, and other defects, despite the many action sequences, make the story sadly forgettable.

In fact, I was tempted to stop watching the series.  Either read a different Coben novel or find a film adaptation of some other Coben story.

Forget it!
