Nell put out the candle and got into bed. She lay very still, straining her ears in the dark; but Sheila Pat made no movement. Dimpling with glee, Nell at last slipped out of bed, slid her feet into her bedroom slippers, flung on her dressing-gown, and took various parcels from beneath her bedclothes. Then she felt her way, pausing to listen, scarcely breathing, across to the Atom's bed. Reaching out for the stocking she knew would be hanging there, she seized a foot. She held a parcel up tight against her mouth to keep her laughter in. The foot had not moved. Nell felt an admiration for the Atom's self-control. She was quite sure she would have called out if someone from out the darkness had suddenly caught hold of her foot. She found the stocking and bundled in her parcels; then she crept across to the door, went out on to the landing and straight into Denis's arms.

"Bother these balusters!" ejaculated he. "One can't walk comfortably in one's sleep for the beastly things!"

She fled recklessly through the dark back to her bed. She had left the door ajar. She lay waiting, determined to try again presently. It was very still; her eyes tried to pierce the darkness. Suddenly something seized the sleeve of her night-gown; she gave a scream.

"Oh," giggled Molly's voice, "I thought it was a stoc—" The giggles fled from the room.

Nell thought how the Atom must be despising her. She determined that, happen what would, she would, next time, make no sound. But when the next minute something lit, with a thud, on her chest, she called out involuntarily. A warm little tongue licked her cheek. "Oh, K.K.! You've given me palpitations of the heart! And you know you're not allowed on beds!" she whispered.

She gave her a kiss and lifted her down to the floor. Then she slipped off the bed, gathered up her parcels once more, and made another attempt, K.K. trotting delightedly at her heels. She got a little way along the passage and was suddenly confronted by Molly, outlined dimly against a window.

"Oh!" gasped Molly, and stumbled noisily back into her room.

Nell drew herself up flat against the wall and waited. Presently something brushed past her knees. She knew it was not K.K.; it was too tall. She gave a little shiver, then stooped and softly put down her hand; it fell on a tight little pig-tail, and Nell drew back with a smothered laugh. So the Atom was crawling about her business! Presently there echoed a frenzied scream from Molly's room; then wild excuses.

"I don't care! You shouldn't crawl! You nearly scared me to death! K.K.'s nearly killed me once already! Why don't you speak, Sheila Pat? I know it's you—I felt you! Oh, you little beast—why won't you speak? Do just say it is you, Atom! Do!"

Kate Kearney barked suddenly; a door opened downstairs. Miss Kezia demanded what was the matter. From overhead came Sarah's quivering voice, declaring that she had a poker and they'd better look out. Then Denis's voice soothingly: "It's all right, Aunt Kezia! Christmas time, you know—excitement—nightmare—so sorry you were disturbed. Good night."
