A little digital trickery puts Sherlock and John (Benedict Cumberbatch
and Martin Freeman), DCI John Luther (Idris Elba) and Detective
Superintendent Stella Gibson (Gillian Anderson) at the scene of the same
crime - and the atmosphere is tense.
Sherlock and Luther naturally square off from
moment one, while Gibson and Watson urge their cocky counterparts to
keep cool heads.
This cracking teaser promotes new episodes of all three shows coming in the months ahead across the BBC channels.
