Ginge, in case Terrier doesn't come back - I wonder if it's the 'abound' in the clue? It reads
Big story abound the end of Troy, possibly a playwright's great one (6).
I initially read it as 'around' and noticed it only later.
Yes malone, "abound" appears to be a misprint for "around", but it's in the wordplay rather than the definition so I assume it's a mistake. Otherwise an excellent puzzle, as one would expect from this setter. I now see there is another thread under the heading "IQ 1446".
