The shrill sound of a siren fills the night air and moments later a helicopter drops an object alongside the Sleuth: a wallet containing two thousand dollars!

These two apparently unconnected events are clues in a tangle of mystery which turns out to be one of the detective brothers’ most exciting adventures.
