A murder suspect one hears (7)

I believe the answer is:

eardrum

'one hears' is the definition.
(I've seen this before)

'a murder suspect' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'a'+'murder'='amurder'
'amurder' with letters rearranged gives 'EARDRUM'.

(Other definitions for eardrum that I've seen before include "It vibrates to sound" , "hearing part" , "Rude ram (anag.)" , "One hears" , "Organ membrane" .)

I've seen this clue in The Sun and The Globe and Mail.
