Professor Hagler strolled into yet another Las Vegas Casino, inserted one bill, hit the maximum play button, and again hit a jackpot hand. Travis Ryan has been following the professor for several days and it was always the same. There would be a visit to five different casinos'; five hands of video poker, five jackpots, and the professor would return home twenty thousand dollars richer. The problem facing Travis was to determine if the professor was a lone cheat or was he a part of a well-oiled gang of thieves that were milking the casinos out of millions of dollars. And the biggest question of all was "how was he cheating?"When the professor was found dead, the case changed from a casino scam to a murder investigation.
