Cold and calculating people in on event (8)
I believe the answer is:
occasion
'event' is the definition.
(occasion is a kind of event)
'cold and calculating people in on' is the wordplay.
'cold' becomes 'C' (eg on taps).
'and' says to put letters next to each other.
'calculating people' becomes 'casio' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
'c'+'casio'='ccasio'
'ccasio' placed within 'on' is 'OCCASION'.
Can you help me to learn more?
(Other definitions for occasion that I've seen before include "Provoke" , "Special event; reason" , "Time when an event takes place" , "A special event, or the time it happens" , "instance" .)
