Hi again Pam,
5d - think about how Cleopatra died and was "bitten" and place it figuratively with single letter from first bit of clue - definition is "yesterday" (as in "when do you want it by"?)
6d - 4 letter "game" + 2 letter "six" + 3 letter "Olympian" then "driving German car" is 2,4 - definition is "he scores" (nothing to do with sport)
I'd honestly never heard of this person before.
9a - triple definition.
