Shy in the Henman Papers? (5)
I believe the answer is:
timid
'shy' is the definition.
(I know that shy can be written as timid)
'henman papers?' is the wordplay.
'henman' becomes 'tim' (Tim Henman).
'papers?' becomes 'ID' (identification papers).
'tim'+'id'='TIMID'
'in the' is the link.
(Other definitions for timid that I've seen before include "Diffident, faint-hearted" , "not forward" , "Easily scared" , "Nervous and easily alarmed" , "Lacking in courage" .)
