In case the series has gone under the radar for fans who didn't catch it upon its initial release, here's everything you need to know, including how to watch it. 

But before you read on, here's what HELLO!'s TV Writer Abby Allen said of the series: "There's nothing like a gritty British crime drama to hunker down with at this time of year, and A Mother's Son is the perfect pick. Starring the wonderful Martin Clunes and Hermione Norris, it'll have you hooked from start to finish."

What is A Mother's Son about?

The miniseries follows mother-of-two Rosie, who faces a horrifying dilemma when she suspects her son could be responsible for the murder of a teenage schoolgirl in their quiet Suffolk coastal village. The drama follows Rosie (Hermione Norris) as she discovers damning evidence that her son could be connected to the heinous murder after a body is found in the woods near their town.

The synopsis continues: "Recently remarried, Rosie lives with her two children, Jamie and Olivia, husband Ben Harley, and his children from a previous marriage, Jessica and Rob. As the newly formed family settle into daily life living together under one roof, Rosie begins to suspect she may be sharing her home with a killer when she finds a pair of blood-splattered trainers hidden under her son Jamie’s bed. At first, Rosie tries to dismiss her suspicions, believing them too incomprehensible to be true. Could her teenage boy be involved in murder?"
