Quietly getting shot of horse in one (in some way)? (5,6)
I believe the answer is:
photo finish
'some way?' is the definition.
The definition suggests a singular noun which matches the answer.
'quietly getting shot of horse in one' is the wordplay.
I cannot quite understand how this works, but
'quietly' could be 'sh' and 'sh' is located in the answer.
'shot' could be 'photo' (I've seen this before) and 'photo' is found in the answer.
'in' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
A single letter 'f' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for photo finish that I've seen before include "Close ending to a race" , "Virtual dead heat in a horse race" .)
