"Why, Wigg," said Constable Nightingale, with a laugh, "you talk of it as if it wasn't a cat at all."

"I don't believe it is. In my opinion it's a spectre cat, a spirit without a solid body. I lifted it with my foot in the street, and not a sound came from it. I kicked it in the passage, and it crept away like a ghost. I let fly my truncheon at it and hit it on the head, and off it went like a shadder, without a whine. It ain't natural. If it comes across me again I advise it to say its prayers."

Which, to say the least of it, was an absurd recommendation to offer to a cat. But Constable Wigg was in an unreasonable and spiteful temper, and he became morose and melancholy when he saw how thoroughly Constable Nightingale was making himself at home in Mrs. Middlemore's kitchen; or perhaps it was the sight of the tempting food on the table which, without lawful invitation, he dared not touch. However it was, he was not allowed much time for gloomy reflection, his thoughts being diverted by the violent slamming of the street door, and by the further sound of a person breathing heavily in her course downstairs.

"It's Mrs. Middlemore," said Constable Nightingale, in a low tone. "I never thought she'd be able to open the door alone with such a wind blowing. We'll give her a surprise."

They heard Mrs. Middlemore stop outside the kitchen, and exclaim, "Well! To think I should 'ave been so foolish as to leave the candle alight! I could 'ave swore I blowed it out before I left the room!" Then she opened the door, and it was well that Constable Nightingale darted forward to her support, for if he had not she would have fallen to the ground in affright, and the supper beer would have been lost to taste, if not to sight. It was as well, too, that he put his face close enough to her lips to partially stifle a kind of a hysterical gurgle which was escaping therefrom. It was, however, a proceeding of which Constable Wigg did not inwardly approve.

"Pluck up, Mrs. Middlemore," said Constable Nightingale, cheerily, "there's nothing wrong. It's only me and my mate, Wigg, who's on night duty here. Everything's as right as a fiddle. Take a pull at the beer--a long pull. Now you feel better, don't you?"

Mrs. Middlemore--her movements being enviously watched by Constable Wigg, whose thirst was growing almost unbearable--removed her lips from the jug, and said:

"Ever so much. But how did you get in?"

"Didn't get in at all," said Constable Nightingale, jocosely; "we were blown in."

"Blown in!"
