Find a hidden passageway.
Direct method is listed below:
When you have to rescue Artie, there's a sequence of numbers behind the counter in which you're hiding from Kid's henchmen. Make note of them. Once you enter the finished speakeasy (with Officer Parker and Trixie), go to the roulette table and bet on those numbers to open the secret passageway.
