Roland was seized by a strange and uncharacteristic impulse of his own. It was suddenly quite impossible to put these living words back into page 300 of Vico and return them to Safe 5. He looked about him: no one was looking: he slipped the letters between the leaves of his own copy of the Oxford Selected Ash, which he was never without. Then he returned to the Vico annotations, transferring the most interesting methodically to his card index, until the clanging bell descended the stairwell, signifying the end of study. He had forgotten about his lunch.
