For an illusionist to make a woman vanish from a cage is merely a parlor trick, because the person must go somewhere; but in this instance the woman really DOES disappear, in full view of an audience, and cannot be found afterwards. This seeming impossibility is the commencement of a completely baffling puzzle, which even Scotland Yard finds hard to crack. And then the magician himself is found murdered in his flat, lending credence to the notion that the woman has also been killed. Scotland Yard enlists the aid of the indomitable Dr. Carruthers, a genius who specializes in solving scientific puzzles. But can Carruthers unravel the diabolical plot--or will THE SILVERED CAGE, a solid metal structure allowing neither entry nor exit, continue to contain its mystery? A scientific detective thriller with several exciting plot twists!
