来自儿童文学的激动人心的新声音，一个赞扬友谊和想象力的永恒故事。

Mabel和她的父母住在海边的美人鱼酒店。 Mabel喜欢留意所有客人的来往。 然后有一天，来了一位特别有趣的老妇人。她越来越大的嗓音，沉重的身体，乌龟一样的眼睛，处处透露着可疑。 为什么没有人知道她的真实姓名？ Mabel认为，只有一个答案。这位客人是个超级大反派。

A timeless story celebrating friendship and imagination, from an exciting new voice in children's literature.

Mabel lives with her parents in The Mermaid Hotel, by the sea. Mabel likes to keep an eye on the comings and goings of all the guests. Then one day a particularly in-ter-est-ing old lady comes to stay. There is something very suspicious about her, with her growly voice and her heavy trunks and her beady-eyed tortoise. And why does no one know her REAL name? There can only be one answer, Mabel decides ... this guest is a SUPERVILLAIN.
