On Monday, Eliska opens the fridge and sees the birthday cake. It is big, with white cream and red berries. It is for her mother's party on Saturday.
星期一，埃利什卡打开冰箱，看到了那个生日蛋糕。它很大，上面有白奶油和红莓果。它是为星期六妈妈的派对准备的。
On Tuesday morning, the cake is smaller. One piece is gone. On Wednesday, there is another missing piece. On Thursday, the cake is half its size.
星期二早上，蛋糕变小了。少了一块。星期三，又少了一块。星期四，蛋糕只剩一半大了。
"Did you eat it?" Eliska asks her brother at breakfast.
“是你吃的吗？”早餐时，埃利什卡问她弟弟。
"No!" he says. "I do not even like berries."
“不是！”他说，“我连莓果都不爱吃。”
Eliska believes him. She looks at the fridge door and thinks hard. Someone comes in the night, and she needs to know who.
埃利什卡相信他。她看着冰箱门，使劲地想。有人夜里来过，她得知道是谁。
That evening, she gets a bag of flour from the cupboard. She puts a thin white line on the kitchen floor. It goes from the door to the fridge. Then she goes to bed and falls asleep fast.
那天晚上，她从橱柜里拿出一袋面粉。她在厨房的地板上撒了一道细细的白线。它从门口一直通到冰箱。然后她去睡觉，很快就睡着了。
In the morning, she runs to the kitchen. The cake is smaller again. And on the floor, there are prints in the flour. They are small and flat, with a round front.
早上，她跑进厨房。蛋糕又变小了。地板上，面粉里有脚印。脚印小小的，扁扁的，前面是圆的。
"Slippers," Eliska says. She follows the prints out of the kitchen and down the hall. They stop at her grandmother's door.
“拖鞋，”埃利什卡说。她顺着脚印走出厨房，沿着走廊往前走。脚印在她奶奶的门口停住了。
Her grandmother sits in bed with a cup of tea. A little cream is on her chin. She looks at Eliska, then at the flour on her slippers. She starts to laugh.
她奶奶坐在床上，手里端着一杯茶。下巴上沾着一点奶油。她看看埃利什卡，又看看自己拖鞋上的面粉。她笑了起来。
"Oh, dear," says Grandma. "Please do not tell your mother. Can I have a bigger piece on Saturday?"
“哎呀，”奶奶说，“请别告诉你妈妈。星期六我能分到大一点的一块吗？”
