When Sydney is stuck with a counterfeit twenty-dollar bill at Red Bud Cove, and is not able to pay for the metal detector and the microscope she had ordered, she gets mad. Mad enough to bring the crooks to justice. She, aided by her twin sister Taryn, and cousins Dylan and Bailey, makes life miserable for the crooks as they constantly investigate how and where the counterfeiters are operating. However, before the criminals are brought to justice the twins are captured, left on a snake and alligator infested island in the middle of the swamp to die, and are conked on the head and left adrift in a boat, without gasoline or paddles, headed for a waterfall into the Forshe River hundreds of feet below. A clue that Sydney uncovers with her metal detector helps lead the twins to """"Mr. Big"""" and with the help of Heber Springs Chief of Police Gary Cupp, the crooks end up behind bars where they belong. | The Foster Twins In The Mystery At Red Bud Cove by Jim D.
