Here is the Sketch
There also was a book with the same title "Something Wicked This Way Comes" written by Ray Bradbury, which was also made into a movie. You could rent that now for your Halloween viewing. But that is not where it ends..."Something wicked this way comes" is a lyric sung in "Double Trouble," a song written by John Williams (with lyrics from Macbeth) for Harry Potter and The Prisoner of Azkaban. You can see a clip of that song here. It was also used as a tagline to the film on posters and other promotional material.
And there you have it....my contribution to creepy bits of literature and pop culture.
Enjoy....if you dare...
