Shortly they were in Las Vegas , stopping in an unfashionable hotel near but not on the Strip.  Mike tried all the games in all the casinos while Jill filled in the time as a show girl-gambling bored her.  Since she couldn't sing or dance and had no act, standing or parading slowly in a tall improbable hat, a smile, and a scrap of tinsel was the job best suited to her in the Babylon of the West.  She preferred to work if Mike was busy and, somehow, Mike could always get her the job she picked out.  Since the casinos never closed, Mike was busy almost all their time in Las Vegas .
