Saruman: The hour is later than you think. Sauron's forces are already moving. The Nine have left Minas Morgul.
Gandalf: The Nine?
Saruman: They crossed the River Isen on Midsummer's Eve, disguised as riders in black.
Gandalf: They've reached the Shire?
Saruman: They will find the Ring, and kill the one who carries it.
