The Secret Seven have a brand-new meeting place in a hidden cave, but somebody else has been using it too. And there are signs of a mailbag robbery! Whoever's been there, they'll return at night -- and the gang is determined to put a stop to it. They'll catch the cheeky intruder, whatever it takes.
