THE RIDDLE CLUB BOOKS

By ALICE DALE HARDY

Individual Colored Wrappers. Attractively Illustrated.

Every Volume Complete in Itself.

Here is as ingenious a series of books for little folks as has ever
appeared since "Alice in Wonderland." The idea of the Riddle books
is a little group of children--three girls and three boys decide to
form a riddle club. Each book is full of the adventures and doings of
these six youngsters, but as an added attraction each book is filled
with a lot of the best riddles you ever heard.

THE RIDDLE CLUB AT HOME

An absorbing tale that all boys and girls will enjoy reading. How the
members of the club fixed up a clubroom in the Larue barn, and how
they, later on, helped solve a most mysterious happening, and how one
of the members won a valuable prize, is told in a manner to please
every young reader.

THE RIDDLE CLUB IN CAMP

The club members went into camp on the edge of a beautiful lake. Here
they had rousing good times swimming, boating and around the
campfire. They fell in with a mysterious old man known as The Hermit
of Triangle Island. Nobody knew his real name or where he came from
until the propounding of a riddle solved these perplexing questions.

THE RIDDLE CLUB THROUGH THE HOLIDAYS

This volume takes in a great number of winter sports, including
skating and sledding and the building of a huge snowman. It also
gives the particulars of how the club treasurer lost the dues
entrusted to his care and what the melting of the great snowman
revealed.
