At last all three children were in the big bed, Rudolf having refused to consider sleeping in the cot, and Betsy, after a gruff good night, departed, carrying the lamp with her. Now that the room was in darkness except for the flickering light of the dying fire, Ann's fears began to come back to her. She sat up in bed and peered round her into the dark corners. "I--I wish Betsy had left the light," she said. "But it would have been no use asking her." "Not a scrap," said Rudolf. "Not that _I_ mind the dark," he added hastily, "_I_ rather like it, only don't let's lie still and--and--listen for things. Let's play something." "Shall we try who can keep their eyes shut longest," suggested Ann. "Oh, that's a stupid game! Beside Peter would beat anyway, for he's half asleep now. Shake him up, Ann." When shaken up Peter refused to admit that, he was even sleepy. He was very cross, and immediately began to accuse Rudolf of having taken his cat. This Rudolf--and also Ann--denied. They had seen Peter smuggle Mittens into bed the second time, but had supposed he must have escaped and followed Betsy out. "No, he didn't neither," Peter insisted. "I had him after she went. He was 'most tamed." "Then," said Ann, "he must be in the room and we might as well have him to play with. Rudolf, I dare you to get up and look for him!" And Rudolf got up--just to show he was not afraid. Before stepping into those dark shadows, however, he armed himself with his tin sword, a weapon he was in the habit of taking to bed with him in case of burglars, and with this he poked bravely under the bed and in all the dark corners, calling and coaxing Mittens to come forth. At last both he and Ann felt sure the cat could not be in the room. "He _must_ have got out somehow," said Rudolf. "Anyway, I sha'n't bother any more looking for him." Still grasping his sword, he climbed back into the big bed between his brother and sister. Peter was still cross and grumbly. He kept insisting that Mittens might have disappeared _inside_ the bed--which was a piece of nonsense neither of the others would listen to. After some discussion Rudolf and Ann agreed that the very nicest thing to do would be to make a tent out of the bedclothes, and seeing Peter was again inclined to nod, they shook him awake and sternly insisted on his joining in the game. By tying the two upper corners of the covers to the posts at the head of the great bed a splendid tent was quickly made, bigger than any the children had ever played in before, so big that Rudolf, who was to lead the procession into its white depths, began to feel just the least little bit afraid,--of what he hardly knew. How high the white walls rose! Not like a snuggly bed-tent, but like--like a real white-walled cave. Being a brave boy, he quickly put these unpleasant thoughts out of his mind, and grasping his sword, crawled on his hands and knees into the dark opening. Behind him came Ann, and behind Ann, Peter.
