Dr Prunesquallor was wiping his eyes, his thick glasses pushed for the moment above his eyebrows. But he was very much on the alert and as soon as his spectacles were again in place he grinned at everyone in turn. His eye lingered for a moment on his sister Irma, who was systematically tearing an expensively embroidered cream-coloured silk handkerchief into small pieces. Behind the dark lenses of her glasses her eyes were hidden from view, but to judge from the thin, wet, drooping line of her mouth and the twitching of the skin on her pointed nose it might be safely assumed that they were making contact with, and covering the inner side of, the lenses of her spectacles with the moisture with which the smoke had filmed them.

The Doctor placed the tips of his fingers and thumbs together and then, separating the tapering extremities of the index fingers, he watched them for a few seconds as they gyrated around one another. Then his eyes turned to the far end of the room where he could see the Earl and his daughter, with the old man between them, approaching the library door. Someone, presumably Flay, seemed to be making a great deal of noise in wrestling with the heavy iron door handle.

The smoke was spreading, and the Doctor, wondering why in the devil’s name the door had not been thrown open, began to peer about the room in an effort to locate the source of the ever-thickening wreaths. As he took a step past Nannie Slagg he saw that she was standing by the table from whose marble surface she had plucked Titus. She was holding him very closely to herself and had wrapped him in layers of cloth which had completely hidden him from view. A sound of muffled crying could be heard coming from the bundle. Nannie’s little wrinkled mouth was hanging open. Her streaming eyes were redder than usual with the stinging smoke. But she stood quite still.

‘My very dear good woman,’ said Dr Prunesquallor, turning on his heel as he was about to float past her, ‘my very dear Slagg, convey his minute Lordship to the door that for some reason that is too subtle for me to appreciate remains shut. Why, in the name of Ventilation, I don’t know. But it does. It remains shut. Take him nevertheless, my dear Slagg, to the aforesaid door and place his infinitesimal head at the keyhole (surely THAT’S still open!), and even if you cannot squeeze the child right through it you can at least give his Lordship’s lungs something to get on with.’
