Danger through, I left (5)

I believe the answer is:

peril

'danger' is the definition.
(peril is a kind of danger)

'through i left' is the wordplay.
'through' becomes 'per' ('per' can mean through or by means of).
'left' becomes 'l' (common abbreviation).
'per'+'i'+'l'='PERIL'

(Other definitions for peril that I've seen before include "Great danger" , "Exposure to harm" , "Danger, hazard" , "risk" , "Source of danger" .)

I've seen this clue in the Evening Standard.
