It was a small note—written in German. Pete Hollister found it hidden in the door of a broken cuckoo clock. When the note was translated, the Hollister children were jubilant. The message was a riddle that made little sense to them—but it was the first clue in a brand new mystery.

Imagine their surprise when Mr. Hollister announced that the whole family—Pete, Pam, Holly, Ricky, and little Sue—were going to Germany to buy toys for their shop, The Trading Post. Now the children could find the wood carver who had made the cuckoo clock and ask him what the puzzling message meant.

Just as the family prepared to board the jet for Europe, someone snatched the damaged clock from Ricky!

When the children visited the famous old wood carver in the Black Forest town of Triberg, they began to untangle the riddle in the message. Then it became a race against a band of desperate thieves to find a valuable golden cuckoo clock which had been stolen from a German museum. It involved them in a wild chase and a thrilling boat ride down the Rhine.

The Hollisters do their special sleuthing in a new setting and enjoy another fascinating mystery-adventure.
