Sherlock Holmes versus D.B. Cooper.....
Same situation as in the movie "The pursuit of D.B. Cooper." Cooper robs the bank and parachutes into the mountains. The only difference is that instead of Robert Duvall's character investigating it, Sherlock Holmes is investigating.
Would Sherlock Holmes be able to determine:
If Cooper survived? And if Cooper did survive, would Holmes be able to track him down and bring him to justice?
