It’s a CO2 cook-off! Chef Kirschoff and Vic’s friends from the Alaskan cruise are back for a carbonation contest, with Erin and Vic acting as two of the judges. It’s fizzy, it’s fun, what could possibly go wrong?

Apparently, someone did not get the memo. At first, when Beryl Batcombe is found dead in the restaurant’s cold room, everyone assumes it was a terrible accident. But as Erin and Vic are drawn into the mystery, it becomes obvious that this was not an innocent mistake.

How could a few bubbles have gone so wrong?
