oh i remember now...it is all coming back...claudia cardinale was to threaten the cia lab/green tower with "DON'T MAKE WAVES" or else, sort of thing....

anyway, mark r was terribly emotional upon meeting her....and i think that i can remember why...he was related...he might even have been her son/grandson for all i know...certainly a 'cuckoo' of the family....

hence the whole TUNISIAN thing...amadeus and mark r researched Tunisian history - the earliest empire of the lot...and slavetrading nexus, i might add....
