This one's based on the Richard Yates story, "Doctor Jack-O'-Lantern". If you've never read Yates' work before I urge you to go do that now. For years his work was out of print and nearly impossible to find until 2001 when his collected short stories were brought together and published in a single volume. The 2008 film adaptation of his hallmark novel Revolutionary Road has also sparked a renewed interest in his writing. These days everything Yates published has been reissued by Vintage Books, so you've really no excuse. Go. Now. Read.
