A whirring, drilling sound at the office door, and a man's hand comes right through the solid wood, swings an imaginary door aside, and lets itself in, astonishing movie-mogul Martin Hammer.

George O. Smith's 1947 story spins a clever hard-SF space-opera tale from the geometry of passing through solid matter. Sharp, ingenious golden-age SF. Read it for a story where a Hollywood producer's day is upended by a visitor who treats walls as no obstacle at all.
