Intro of Suspicious Minds is shocking (6)
I believe the answer is:
scares
'is shocking' is the definition.
'intro of suspicious minds' is the wordplay.
'intro of' suggests taking the first letters.
'minds' becomes 'cares' (I've seen this before).
The initial letter of 'suspicious' is 's'.
's'+'cares'='SCARES'
(Other definitions for scares that I've seen before include "Causes fear" , "Alarms" , "Terrifies" , "Frightens or intimidates" , "Affrights" .)
