The Terror stopped short too, pondering the suggestion; then he said: “By Jove, yes. This would be a good time to work that valerian dodge. And it would mean that we should have to use our bicycles again for the good of the home. The more we can say that we’ve used them for it, the less any one can grumble about them.”

“Most cats are shut up now,” said Erebus.

“Yes; we must catch the morning cats. They get out quite early—when people start out to work,” said the Terror.

Among the possessions of the Twins was an American clock fitted with an alarm. The Terror set it for half past five. At that hour it awoke him with extreme difficulty. He awoke Erebus with extreme difficulty. Five minutes later they were munching bread and butter in the kitchen to stay themselves against the cold of the bitter November morning; then they sallied forth, equipped with rags, string and the bottle of valerian.

They bicycled to Muttle Deeping. There the Terror poured valerian on one of the rags and tied it to the bicycle of Erebus. Forthwith she started to trail it to the cats’ home. He rode on to Great Deeping and trailed a rag from there through Little Deeping to the cats’ home. When he reached it he found Erebus’ bicycle in its corner; and when, after strengthening the trail through the little hanging door with a rag freshly wetted with the drug, he returned to the house, he found that she was already in bed again. He made haste back to bed himself.

It had been their intention to go down to the home before breakfast and put the cats they had attracted to it into hutches. But they slept on till breakfast was ready; and the fragrance of the coffee and bacon lured them straight into the dining-room. After all, as Erebus told the hesitating Terror, there was plenty of time to deal with the new cats, for Aunt Amelia could not reach Little Deeping before eleven o’clock. They could not escape from the home. The Twins therefore devoted their most careful attention to their breakfast with their minds quite at ease.

Then there came a ring at the front door; and still their minds were at ease, for they took it that it was a note or a message from a neighbor. Then Sarah threw open the dining-room door, said “Please, ma’am, it’s Lady Ryehampton”; and their Aunt Amelia stood, large, round and formidable, on the threshold. Behind her stood Miss Hendersyde looking very anxious.

There was a heavy frown on Lady Ryehampton’s stern face; and when they rose to welcome her, she greeted them with severe stiffness. To Erebus, the instructor of parrots, she gave only one finger.

Then in deep portentous tones she said: “I came down to pay a surprise visit to your cats’ home. I always do. It’s the only way I can make sure that the poor dear things are receiving proper treatment.” The frown on her face grew rhadamanthine. “And last night I saw your Uncle Maurice at the station—he did not see me—with cats, London cats, in baskets. On the labels of two of the baskets I read the names of well-known London cat-dealers. I do not support a cats’ home at Little Deeping for London cats bought at London dealers. Why have they been brought here?”

Sir Maurice opened his mouth to explain; but the Terror was before him:
