While on an archaetological expedition in Mexico, Terry and Dr. Joshua Pitt came across a clue to the buried treasure. The clue was a cipher carved on a stone tablet. Before the professors had time to translate the cipher, the tablet disappeared and with it Dr. Pitt! Terry tells Nancy of his sussuspicions of the Tinos, a Mexican couple posing as scientists, who vanished the same night as Dr. Pitt. Recommended for ages 8 to 12.
