‘How terrifying!’ said Frodo. There was another long silence. The sound of Sam Gamgee cutting the lawn came in from the garden.
‘How long have you known this?’ asked Frodo at length. ‘And how much did Bilbo know?’
‘Bilbo knew no more than he told you, I am sure,’ said Gandalf. ‘He would certainly never have passed on to you anything that he thought would be a danger, even though I promised to look after you. He thought the ring was very beautiful, and very useful at need; and if anything was wrong or queer, it was himself. He said that it was “growing on his mind”, and he was always worrying about it; but he did not suspect that the ring itself was to blame. Though he had found out that the thing needed looking after; it did not seem always of the same size or weight; it shrank or expanded in an odd way, and might suddenly slip off a finger where it had been tight.’
‘Yes, he warned me of that in his last letter,’ said Frodo, ‘so I have always kept it on its chain.’
‘Very wise,’ said Gandalf. ‘But as for his long life, Bilbo never connected it with the ring at all. He took all the credit for that to himself, and he was very proud of it. Though he was getting restless and uneasy. Thin and stretched he said. A sign that the ring was getting control.’
‘How long have you known all this?’ asked Frodo again.
‘Known?’ said Gandalf. ‘I have known much that only the Wise know, Frodo. But if you mean “known about this ring”, well, I still do not know, one might say. There is a last test to make. But I no longer doubt my guess.
‘When did I first begin to guess?’ he mused, searching back in memory. ‘Let me see – it was in the year that the White Council drove the Dark Power from Mirkwood, just before the Battle of Five Armies, that Bilbo found his ring. A shadow fell on my heart then, though I did not know yet what I feared. I wondered often how Gollum came by a Great Ring, as plainly it was – that at least was clear from the first. Then I heard Bilbo’s strange story of how he had “won” it, and I could not believe it. When I at last got the truth out of him, I saw at once that he had been trying to put his claim to the ring beyond doubt. Much like Gollum with his “birthday-present”. The lies were too much alike for my comfort. Clearly the ring had an unwholesome power that set to work on its keeper at once. That was the first real warning I had that all was not well. I told Bilbo often that such rings were better left unused; but he resented it, and soon got angry. There was little else that I could do. I could not take it from him without doing greater harm; and I had no right to do so anyway. I could only watch and wait. I might perhaps have consulted Saruman the White, but something always held me back.’
‘Who is he?’ asked Frodo. ‘I have never heard of him before.’
‘Maybe not,’ answered Gandalf. ‘Hobbits are, or were, no concern of his. Yet he is great among the Wise. He is the chief of my order and the head of the Council. His knowledge is deep, but his pride has grown with it, and he takes ill any meddling. The lore of the Elven-rings, great and small, is his province. He has long studied it, seeking the lost secrets of their making; but when the Rings were debated in the Council, all that he would reveal to us of his ring-lore told against my fears. So my doubt slept – but uneasily. Still I watched and I waited.
‘And all seemed well with Bilbo. And the years passed. Yes, they passed, and they seemed not to touch him. He showed no signs of age. The shadow fell on me again. But I said to myself: “After all he comes of a long-lived family on his mother’s side. There is time yet. Wait!”
‘And I waited. Until that night when he left this house. He said and did things then that filled me with a fear that no words of Saruman could allay. I knew at last that something dark and deadly was at work. And I have spent most of the years since then in finding out the truth of it.’
‘There wasn’t any permanent harm done, was there?’ asked Frodo anxiously. ‘He would get all right in time, wouldn’t he? Be able to rest in peace, I mean?’
‘He felt better at once,’ said Gandalf. ‘But there is only one Power in this world that knows all about the Rings and their effects; and as far as I know there is no Power in the world that knows all about hobbits. Among the Wise I am the only one that goes in for hobbit-lore: an obscure branch of knowledge, but full of surprises. Soft as butter they can be, and yet sometimes as tough as old tree-roots. I think it likely that some would resist the Rings far longer than most of the Wise would believe. I don’t think you need worry about Bilbo.
