This is the first mystery-oriented Mad House Glads story. At the time, many of the Archie Comics bands (The Archies, Josie and the Pussycats, etc.) began to appear in stories of this genre to capitalize on the success of the Hanna-Barbera cartoon, Scooby Doo.
Story is continued in the next issue.
A&B Supermarket is a parody of A&P.
