From his vantage point he was able to get a clear view of three doors in a corridor, the central one belonging to the chamber of her ladyship, the seventy-sixth Countess of Groan. It was stained black and had painted upon it an enormous white cat. The wall of the landing was covered with pictures of birds and there were three engravings of cacti in bloom. This door was shut, but as Mr Flay watched the doors on either side were being constantly opened and closed and figures moved quickly in and out or up and down the landing, or conversed with many gesticulations or stood with their chins in the curled palms of their hands as though in profound meditation.

‘Here,’ said Flay without turning round.

Steerpike was immediately at Flay’s elbow. ‘Yes?’ he said.

‘Cat door’s hers,’ said Flay removing his eye, and then, stretching his arms out he spread his long fingers to their tips and yawned cavernously.

Young Steerpike glued his eye to the hole, keeping the heavy gold frame from swinging back with his shoulder. All at once he found himself contemplating a narrow-chested man with a shock of grey hair and glasses which magnified his eyes so that they filled the lenses up to their gold rims, when the central door opened, and a dark figure stole forth, closing the door behind him quietly, and with an air of the deepest dejection. Steerpike watched him turn his eyes to the shock-headed man, who inclined his body forward clasping his hands before him. No notice was taken of this by the other, who began to pace up and down the landing, his dark cloak clasped around him and trailing on the floor at his heels. Each time he passed the doctor, for such it was, that gentleman inclined his body, but as before there was no response, until suddenly, stopping immediately before the physician in attendance, he drew from his cape a slender rod of silver mounted at the end with a rough globe of black jade that burned around its edges with emerald fire. With this unusual weapon the mournful figure beat sadly at the doctor’s chest as though to inquire whether there was anyone at home. The doctor coughed. The silver and jade implement was pointed to the floor, and Steerpike was amazed to see the doctor, after hitching his exquisitely creased trousers to a few inches above his ankle, squat down. His great vague eyes swam about beneath the magnifying lenses like a pair of jellyfish seen through a fathom of water. His dark grey hair was brushed out over his eyes like thatch. For all the indignity of his position it was with a great sense of style that he became seated following with his eyes the gentleman who had begun to walk around him slowly. Eventually the figure with the silver rod came to a halt.

‘Prunesquallor,’ he said.

‘My Lord?’ said the doctor, inclining his grey hayrick to the left.
