The Metropolitan Police have created a series of videos aimed at educating young people about the law of murder.
First up you get a trailer showing a murder at a party. Then by visiting a special page setup on Facebook you can get to see the build up to the incident from the perspective of half a dozen suspects who attended the party.
We won't spoil the suspense here, but we do think that most lay peoples understanding of the law will be widened by viewing these clips.
And while the subject matter is clearly serious, you'll find it hard not to cackle at Rochelle's innovative dancing style.
