Stanley Tucci is a Hannibal Lecter-esque murderer on death row and Lydia West, of “Years and Years” and “It’s a Sin,” is a young investigative journalist.
In this compact four-episode mystery from “Doctor Who” and “Sherlock” showrunner Stephen Moffatt, the Doctor himself, David Tennant, is a vicar and family man who quickly gets himself into a sticky situation when his son’s math tutor goes missing. Stanley Tucci is a Hannibal Lecter-esque murderer on death row and Lydia West, of “Years and Years” and “It’s a Sin,” is a young investigative journalist. It’s all played a bit broadly, and those who have proposed that Moffatt might be Britain’s Ryan Murphy are not far off. But the star power is undeniable and the length is just right for those who are intrigued enough to stay with this tale, though it might be just a little too unbelievable for some.
