A Rembrandt concocted with guile and craft may go missing here (7,8)
I believe the answer is:
bermuda triangle
'craft may go missing here' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'a rembrandt concocted with guile' is the wordplay.
'concocted with' indicates an anagram.
'a'+'rembrandt'='arembrandt'
'arembrandt' with its letters anagrammed with 'guile' gives 'BERMUDA TRIANGLE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for bermuda triangle that I've seen before include "associated with disappearing craft?" , "mysterious place" , "Area of mystery" , "notorious danger area?" , "Place where ships have been mysteriously lost" .)
