The Third Eye. Level 3
2nd edition

In just two months, five customers had large amounts of money stolen while in flight ! Such cases became a headache for the cops. Harried and frustrated for a while, they found a clue while screening the names of all the customers. One day, when the thief showed up again on the airplane, a cop quietly followed. The cop sat there nonchalantly with his "third eye" watching and waiting for the fish to bite.
