THE SIRENS BALL PRESENTS:

Murder on the Willamette
A Siren Themed Murder Mystery
River Dinner Cruise • Ages 18+


In a bygone vision of 1920s–30s Portland, when riverboats carried secrets and glamour masked danger, the merfolk guilds of the Pacific Northwest gather for a single, sacred night. This rare convergence of merkind is a ceremonial gathering where alliances are renewed, rivalries simmer, and the fate of the waters is quietly negotiated.

This year, something has gone terribly wrong.
Murder on the Willamette is an immersive siren fantasy murder mystery dinner cruise that invites guests aboard an elegant river voyage where history, folklore, and intrigue intertwine.

As the night unfolds, guests will dine, dance, and drift through live music and performances woven into the story itself. Clues surface like bubbles from the deep. Loyalties are tested, and somewhere among the gathered guilds, a crime has shattered the ritual.

​Throughout the evening, expect:
  • An interactive murder mystery experience rooted in siren lore
  • A lavish buffet dinner served aboard the vessel
  • A no host bar offering classic cocktails and spirited libations
  • Live, high-energy vintage dance music inspired by 1920s–30s riverboat culture, aquatic themes, and early American roots sounds, sultry, rhythmic, and irresistibly swimmable
  • Sultry Performances that blur character, creature, and myth
  • Mermazing prizesfor sharp eyes and clever minds
  • The Majesty of the Waters Contest

Guests may choose their level of participation, from quiet observer to active conspirator.

Costumes or themed formal attire required, Think sirens of the roaring 20's age, river witches, guild envoys, and aquatic mythic figures pulled from Portland’s watery past.
​
Who will dare to solve the mystery?
Will justice prevail, or will the river claim another secret?
