TV detective revealing number of fingers? (5)
I believe the answer is:
frost
This could be a double definition.
'tv detective' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'number of fingers?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'revealing' acts as a link.
(Other definitions for frost that I've seen before include "Frozen deposit" , "Robert ---, US poet" , "RD Wingfield's detective" , "Ice crystals forming a white deposit" , "Frozen dew" .)
