Story one may mistakenly associate with 'Rip Van Winkle'? (3,3,5)
I believe the answer is:
the big sleep
'story' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for the big sleep that I've seen before include "No catnap" , "Raymond Chandler novel, Bogart film" , "Bogart/Bacall film of 1946" , "[BACALL & BOGART] in this!" , "associated with Rip Van Winkle?" .)
