So far Otto read, with waxing indignation; and here his fury overflowed. He tossed the roll upon the table and stood up. ‘This man,’ he said, ‘is a devil. A filthy imagination, an ear greedy of evil, a ponderous malignity of thought and language: I grow like him by the reading! Chancellor, where is this fellow lodged?’

‘He was committed to the Flag Tower,’ replied Greisengesang, ‘in the Gamiani apartment.’

‘Lead me to him,’ said the Prince; and then a thought striking him, ‘Was it for that,’ he asked, ‘that I found so many sentries in the garden?’

‘Your Highness, I am unaware,’ answered Greisengesang, true to his policy. ‘The disposition of the guards is a matter distinct from my functions.’

Otto turned upon the old man fiercely, but ere he had time to speak, Gotthold touched him on the arm. He swallowed his wrath with a great effort. ‘It is well,’ he said, taking the roll. ‘Follow me to the Flag Tower.’

The Chancellor gathered himself together, and the two set forward. It was a long and complicated voyage; for the library was in the wing of the new buildings, and the tower which carried the flag was in the old schloss upon the garden. By a great variety of stairs and corridors, they came out at last upon a patch of gravelled court; the garden peeped through a high grating with a flash of green; tall, old, gabled buildings mounted on every side; the Flag Tower climbed, stage after stage, into the blue; and high over all, among the building daws, the yellow flag wavered in the wind. A sentinel at the foot of the tower stairs presented arms; another paced the first landing; and a third was stationed before the door of the extemporised prison.
