Dark Heart

All the episodes from the British television crime drama in which a police detective tormented by the memory of his own parents' double murder must investigate a series of ruthless killings in London. Still recovering from the trauma of his parents' death at the age of sixteen, DI William Flagstaffe (Tom Riley) works hard to unravel the most distressing of investigations despite their ability to draw parallels with Will's darkest memories. With a spate of sex offenders being brutally murdered all in a similar fashion, Will must work fast if he is to locate the perpetrator before more lives are claimed, but what he encounters may be the most disturbing finding in his entire career.
