From IMDB:

Follows the lives of suburban families whose secrets and lies are made public by the appearance of a stranger.

From Netflix you can stream the 8 roughly 50 minute episodes of this thriller based on the book The Stranger which Harlan Coben wrote in 2015.

Starting in 1995 Harlan Coben (who at this writing is 58 years old) has written a book a year. If you have never read a book by Coben and if you like clever thrillers, you are in for a treat. So far every Coben book I have read was gripping and a real pleasure.

Plot is all important and usually complicated in a Coben novel. However his treatment of character is well done. In the TV version the actors do not disappoint:

• Richard Armitage leads the story as Adam Price, the distraught husband seeking his missing wife Corinne played by Dervla Kirwan.
• Siobhan Finneran (who played Clare Cartwright in the powerful TV series Happy Valley) plays the detective Johanna Griffin.
• Paul Kaye (who was Thoros of Myr  in Game of Thrones) plays to perfection the bent detective Patrick Katz.
• Shaun Dooley (who played Steve Richards in DCI Banks) plays the neighbor Doug Tripp.

All this actors have incredibly extensive resumés. You just cannot go wrong watching this series.
