The Onset Bay Association will host a WhoDunIt fundraiser at 6 p.m. on Saturday night, March 5, at Stone Path Malt, 11 Kendrick Road. 

The WhoDunIt is titled “Curse of the Comet,” and features a murder mystery where watchers solve the question of who killed a famed archeologist who’s accused of robbing an ancient tomb.

The night will be put on by WatermelonAlligator Theatre Company, a consortium of theater professionals.

Tickets cost $40 a person, which includes appetizers, the association says on its website.
