Vehicle detective accounts for goes straight to the heart (7)
I believe the answer is:
cardiac
'the heart' is the definition.
(I've seen this before)
'vehicle detective accounts for goes straight' is the wordplay.
I cannot quite understand how this works, but
'vehicle' could be 'car' (car is a kind of vehicle) and 'car' is present in the answer.
'detective' could be 'di' (Detective Inspector abbreviation) and 'di' is found within the answer.
The remaining letters 'ac' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for cardiac that I've seen before include "Relating to the heart" , "Pertaining to the heart" , "Sort of surgery" , "Physiologically, of the heart" , "Of the heat, perhaps illness" .)
