But he wasn't there. His voice, however, could be heard crying lustily, and it seemed to come from overhead. Yet the little boy was not on the high platform, from which he had been seen to topple backward.

Where was Trouble?

This was the question the Curlytops asked themselves. And it was what their playmates wanted to know, as did the postman.

But before we settle that question I want to answer several inquiries that I feel sure some of my new readers are asking, and among these is this:

"Who are the Curlytops?"

Those who have read the previous books of this series do not need to go over this part I am writing now. They may skip it and get on with the story. Others may wish to know something about Ted, Janet and Trouble.

"Curlytops" was not their right name. As you have noticed, it was Martin. Theodore Baradale Martin was called Ted, or Teddy, and Janet's name was more often shortened to Jan. William was called Trouble as I have mentioned.

The name "Curlytops" was given the two older children because of their curly, golden heads of hair. They lived with their father and mother, Mr. and Mrs. Richard Martin in the city of Cresco, in one of our Eastern states. Mr. Martin kept a store.

The Curlytops were introduced first in the book about Cherry Farm. After that they had fun and adventures on Star Island, they were snowed in, as the book of that name tells, and later they went to Uncle Frank's ranch in the West. At Silver Lake they had fun on the water with Uncle Ben.

The book which was written just before this is called "The Curlytops and their Pets," and tells how the children cared for some dogs, a cat, a monkey, a parrot and an alligator that Uncle Toby left in their charge when he thought he had to go to South America.
