The Chelsea Detective: Season 1, Episode 4

1 - 4: A Chelsea Education

At first glance, Oliver Cowie — devoted family man, respected educator, all-round good guy — seems an unlikely murder victim, until he's found in a pool of blood, bludgeoned to death in his study. But scratch the surface and it turns out there's no shortage of suspects, ranging from his own wife to feuding colleagues, a vengeful ex-pupil, disgruntled parents, and a rather too-familiar family cleaner.
