Stein's latest criminal picture? (7)
I believe the answer is:
mugshot
'criminal picture?' is the definition.
(picture of a criminal)
'stein's latest' is the wordplay.
'stein's' becomes 'mug's' (a stein is a mug-like vessel).
'latest' becomes 'hot' (both can mean the most up-to-date or modern).
'mugs'+'hot'='MUGSHOT'
(Other definitions for mugshot that I've seen before include "ID photograph (colloq.)" , "Police snap" , "Photograph taken for police records" , "Photo of criminal" , "Passport photograph?" .)
