The Last Role of Halcyon Helen Walkthrough
You can now travel to Eridanos.
Upon arrival, take the lift down into the welcoming area and speak to Bellhop Norville for some clues. Make your way to the Grand Colonial Hotel and find Constable Keene in the Ballroom just behind the elevators in the main lobby area. Speak to the Constable. You are also introduced to Dr. Goodnight who is quick to endorse her technological breakthrough: the Discrepancy Amplifier. Equip it in a weapon slot and begin your investigation.
Note that the Discrepancy Amplifier will be used throughout the Murder on Eridanos storyline. It is advised that you reserve a weapon slot for it during your adventure on Eridanos.
Look through the amplifier and investigate the body. Afterwards, investigate the discrepancy just a few steps ahead to discover the footprints and have the amplifier analyze the dirt to get your next clue.
