Acid The police have a difficult case. There is
a secret message in a special box. The box
can only be opened with a four number
code. If the wrong number is pressed,
t inside the box will destroy the
message. There is a clue:
22,9,9 - 9,24-9, 22 - 9,9,9
Sherlock Holmes looks at it and presses
7943. The box opens. The police officers
are amazed.
