Escape expert (7)
I believe the answer is:
houdini
'escape expert' is the definition.
(I know that Houdini is a escape expert)
This is all the clue.
(Other definitions for houdini that I've seen before include "tie-break ace" , "Showman" , "World-famous escapologist" , "Entertainer bound" , "Harry . . . . . . ., famed American escapologist" .)
