I enjoyed this challenge by Columba, but, having solved the rest satisfactorily, am uneasy about the solution to 19 down. I suppose it must be EASTERLING, but am unsure as to the logic. Middleman? Or what? Can one of you enlighten me?
The only word Chambers online gives that fits this pattern is BUNIA which is apparently a city in Democratic Republic of Congo where lots of' tr*ding takes place. Can the name also apply to the one who does the tr*ding?
