Turning up in cab, murder dance! (5)
I believe the answer is:
rumba
'dance' is the definition.
(rumba is a type of dance)
'turning up in cab murder' is the wordplay.
'turning up' says the letters should be written backwards.
'in' indicates a hidden word.
'abmur' can be found hidden inside 'cab murder'.
'abmur' written backwards gives 'RUMBA'.
(Other definitions for rumba that I've seen before include "Style of dance" , "Latin American dance" , "Ballroom dance of Cuban origin" , "What to perform" , "Latin beat" .)
