Three years after the events of Detective Butler: Maiden Voyage Murder, Gilligan Golder is now CEO of his late father's life insurance company, where Butler also now works as a fraud investigator. At the same time, Gilligan has been attending classes at the prestigious Diamond University. The company's investors have great expectations for Gilligan upon his graduation.

One day, Gilligan and Butler learn about a Detection Club at the university. At the same time, a serial killer has been targeting the female students, each victim's heart ripped out from a gaping wound. As none of the hearts have been found -- apparently stolen -- the killer has been nicknamed "The King of Hearts."

Tensions have grown on campus as the female students fear becoming the next victim, and the male students fear being falsely accused as the killer. In the midst of all this, Gilligan falls in love with one of the girls, but lacks the confidence to pursue her.

Eventually, a new victim is discovered: one of the members of the Detection Club.

And the prime suspect?

Detective Butler.

Gilligan refuses to believe it. With Butler as the brains and Gilligan doing the legwork, they work together to pursue the truth and catch the true killer.

The other members of the Detection Club all have secrets they want to remain hidden. Will Gilligan come to regret the truth he ends up discovering?

What are the consequences of telling comforting lies over the harsh truth?

And what are the consequences of believing them?

The primary gameplay is within your own mind as you try and solve the mysteries yourself. The game will provide you with Case Notes and Lecture Notes to help you keep track of the characters, clues, and other important information.

You will encounter choices to personalize your experience and test your skills of deduction, but they won't significantly influence the outcome of the story. Instead, you'll be taken on an emotional rollercoaster, with many exciting twists and turns as the mysteries slowly unravel themselves.

In addition to the overarching mystery of the King of Hearts Serial Murders, each chapter has at least one dedicated mystery for you to solve. Please enjoy solving all of them!


The Chapter 1 demo is about 1-2 hours long. It introduces you to the major characters in the game and sets up a few mysteries to solve.
