trivia game

This is in RotK, when uruks think Frodo and Sam are deserting orcs...

"And stay there, or you'll know it, when I come down the line!"

"Not likely," answered Gandalf, "though they came to the balance of a hair."

You're pretty good at coming up with tough ones too. I can't place that one off the top of my head.

The Two Towers

Or shall we just forget this one? OK, hint...(It's in "The Voice of Saruman" chapter.)

Found it.
But I had reasons for trying; some merciful and some less so.

Next.
Bilbo was doing splendidly.

This was the sort of stuff they liked: short and obvious.

ahem...yes...I prefer short and obvious too!

"Behold Isildur's Bane!"...

Boromir's eyes glinted as he gazed at the golden thing.

Next:
Only by a hair did they escape.

Which book is it from?

Return of the King

This is when Sam and Frodo are leaving the Tower of Cirith Ungol.

A bell clanged; and from the Watchers there went up a high and dreadful wail.

New one:

"Cast off these cold rags!"

Run naked on the grass, while Tom goes a-hunting!

next:
Safest not to

require a hint! Can you tell us which book?

The Two Towers.

"Safest not to" isn't fair, Findaluin. In the first post of this trivia game, Andustar made it clear that you have to use a full sentence:

"now its not that simple, there are some rules to it - it must be at least one full sentance, but the difficulty can range from 'eleventy one years are too short a time to spend among you' to 'but they do' ."

Please, a different one!

It is a full sentence. Forgot to add the punctuation though.

I give up. Tar Melian, you're our only hope.

Another clue:
its in the second book

You already gave that clue.

also known as book 4.
