When Johnny plays the Wheel of Fortune, the last number he bets on is 19, which of course is featured extensively in the Dark Tower books. After dropping off Sarah at her house, Johnny calls a cab and it mentions driving up "Flagg Street."

At the very beginning of the novel, when Entragian stopped Peter and Mary, a small bag with Marijuana is found. In that moment, Mary remembers her sister-in-law who has married a guy called Roger Finney. Means something to you? Yeah, thats, in my opinion, another name for Randall Flagg. And in addition, the bag has a small sticker of Smiley, just as Flagg has in his jacket.

Mr. Gray: "What is 19, besides a prime number?"

Need I say more? How exactly does this DT number show up in Jonesy's mind? King did start writing this one in 1999. Mayhap 99 shows up and I missed it somewhere.

    There are several references to the Dark Tower Series. Edgar refers to himself as a "gunslinger" (pg 433). One of Edgar's major works is "Roses Grow from Shells." His ex-wife tattoos a rose onto her breast. Roses are also mentioned several times in the novel. The main antagonist wears a red robe similar to that of the Crimson King. His daughter's name ( Ilse Marie Freemantle) has 19 letters in it. Edgar's E-mail is EFree19 and his real estate agent's is SmithReality9505, both of which have numbers the amount to 19, which constant readers will recognize. Along with these other "19's", the first big storm (or "Alice") occurred in 1927, which when added together makes 19; and the flight he takes to Florida is flight 559. Pam's room number is 847 which added together is 19. Edgar's artistic abilities seem to parallel those of Patrick Danville, especially the ability to remove things from reality by drawing and then erasing them. Nan Melda loses two fingers on her right hand on a beach, which also happens to Roland Deschain at the beginning of the Drawing of the Three. Charley the Lawn Jockey (pg 568) shares the name of Charlie the Choo Choo, and the root "char," meaning death, also echoed when Edgar thinks about having people sit in the "char" when he has to think sideways to mean "chair". In one passage of the book, Edgar compares life to a wheel, in the sense of always coming around to the beginning, one of the main philosophies of the Dark Tower. The idea that drawings or paintings can change reality is another recurring motive.

Edgar Freemantle's daughter is going home on flight number 559. If you add the three numbers together (5 5 9) you get 19, which is a prominent number in the Dark Tower series. This could be a possibly intentional connection.
