He escaped to become famous (7)
I believe the answer is:
houdini
'he escaped to become famous' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for houdini that I've seen before include "Escape artist, d. 1926" , "American escapologist, d. 1926" , "Showman" , "Weiss -" , "Entertainer bound" .)
