Anna Maxwell Martin plays Theresa
Who is Theresa? Theresa is a resident of a picturesque suburban street, Hollington Drive, where she lives with her partner, Fraser, and son, Ben. Her sister's family comes to visit one sunny afternoon for a barbecue, when her son and niece ask to play in a nearby park. Theresa is reluctant to let them go unaccompanied but ultimately decides to do so, descending into panic when they do not return home at the agreed time. She later finds them arguing on the edge of the woods, which plants suspicion in her mind when another local child is reported missing that evening.

Martin has been all over our screens as of late and has received high praise for her versatility, portraying icy DCS Patricia Carmichael in Line of Duty, flustered parent Julia Johnston in Motherland, botanist Edith Dubois in The Irregulars and Kelly Major in Code 404. On the big screen, she recently appeared in Armando Iannucci's reimagining of classic Dickens story The Personal History of David Copperfield.
