## Description

A murder has been committed in Brisbane, Australia. A Marine Biologist, Trudy Erhardt has been found dead with a bullet wound to her head. The evidence has been collected for you, it’s your job to piece it all together and work out who it was that killed the victim.

Review: Great way to spend an evening in! - Good challenging mysteries. Not completely obvious and a good brain-teasing alternative for date night. 3-4 hours of mystery solving involved. Ordered 1 and then ordered more. Shared them out with the fam too - hope to do one at the next family games night.
Review: Fun, at home, date night game. - Made for a great, at home, date event. Hubby and I spent about 4 hours total (Part 1 on Saturday night, Part 2 on Sunday night) solving this murder. We've used similar games before, first time buying from Cryptic Killers. Will definitely purchase another one. Was challenging and fun!
