December 1948 Episode 18 in syndication stars Alan Ladd as writer Dan Holiday. When a child's copybook turns up at Box 13, followed by a letter asking for its return, Dan thinks nothing of it. But upon meeting the book's alleged owners, Dan finds there's something off about the whole business. Could the bizarre and grotesque drawing inside the book captioned "The Sad Night" be something more than just a child's scrawl?
