The brief
'Welcome, my lords, to Isengard!' he said. 'We are the doorwardens. Meriadoc, son of Saradoc is my name; and my companion is Peregrin, son of Paladin, of the house of Took. The Lord Saruman is within; but at the moment he is closeted with one Wormtongue, or doubtless he would be here to welcome such honourable guests.'
