Reserved hotel inside for Wile Ethelbert? (6)
I believe the answer is:
coyote
'wile ethelbert?' is the definition.
(Wile E Coyote, Looney Tunes character)
'reserved hotel inside' is the wordplay.
'reserved' becomes 'coy' (both can mean shy).
'inside' means to look at the middle letters.
The middle of 'hotel' is 'ote'.
'coy'+'ote'='COYOTE'
'for' is the link.
(Other definitions for coyote that I've seen before include "Wild canine" , "Confines" , "Beast" , "North American prairie wolf" , "Wolf-like animal" .)
