Nowhere to Hyde

On their way home from the Malt Shop, the gang encounters "The Ghost of Mr. Hyde", a known jewel thief, sneaking into a spooky house. The house turns out to be the home of Dr. Jekyll (great-grandson of the fictional character), who fears he may be transforming into the Ghost of Mr. Hyde. The gang begins searching the house for clues, pegging the maid as a likely suspect, but are pursued at every turn by the ghost.
