Shards of Narsil did a great job, if I'm right of course!
Blind man and deaf man
standing at dusk. - Nazgul (effectively blind) and Gaffer (pretty deaf)
Who of you tells me
what are their tasks? - Legate of Amon Lanc
and Gardner to the Gentry
First of them second. - This particular Nazgul is Khamul, 2ic of the lot
Second's - third house. -Hmmm, tricky, we're talking about the Gaffer here yes? OK possible interpretations - they are at Bag End, that will become Gaffer's third house (first in Tighfield, second Bagshot Row, does he moves in with Sam and Rosie?). Maybe Gaffer's third house - Tighfield- somewhere in Hobbiton (as Holman would have been in Bagshot Row at first), Bagshot Row. Or Tighfield, Bagshot Row, New Row/Sharkey's End.
Blindness and deafness,
forest and garth. - Khamul's lair is in Mirkwood, Gaffer's in the garden
Rich man and poor man, - Khamul's probably loaded, Gaffer was glad of a sack of spuds
brink of the day.
Enemy and a son - Sam, - Khamul's enemy, Gaffer's son
not far away.
How am I doing Legate?
