Blood on the Handle (Choose Your Own Adventure #33)

Beware and Warning!
 
This book is different from other books.
 
You and YOU ALONE are in charge of what happens in this story.
 
There are dangers, choices, adventures, and consequences. YOU must use all of your numerous talents and much of your enormous intelligence. The wrong decision could end in disaster - even death. But, don't despair. At any time, YOU can go back and make another choice, alter the path of your story, and change its result.

Ever since your parents disappeared mysteriously in the Caribbean, you have lived with your wealthy Uncle Morgan in his gothic mansion. Morgan is a writer and world traveler, and every day with him has been exciting. The adventure of life with Morgan changes when he, too, vanishes - leaving behind just one clue: a dagger stabbed into the floor of his study, with a bloodied handle. Morgan's life is full of mysteries, and you'll need to figure out who to trust and who is an enemy as you search for your only living relative.
