Get your Sherlock on

If you want to get really involved, like, literally, Brass Union is hosting a Murder Mystery night on Saturday evening, where attendees will be asked to play a role in a game of “Who Done It?” The staff will stage a crime while in full costume and character, and bar patrons will be left to search for clues and question suspects to find the guilty party. The grand prize? A $100 gift card to the bar. Attendees will also be treated to a costume contest, what we’re told are “piles of candy” and Halloween-themed set from DJ J-Wall. Oct. 29 at 8 p.m., 70 Union Sq., Somerville, 21+, free, brassunion.com.

Brews and Boo’s

Bukowski Tavern’s Inman Square location will host Jack’s Abby Craft Lagers over Halloween weekend for their BOOkowski Hallowen Bash. While the bar screens classic horror films, Jack’s Abbey will serve up Brewery Maker, Wet Hop Lager, Pumpkin Crop Lager, Sibling Rye-valry and others from their Framingham vault. Candy and spooky snacks from chef Brian Poe will also be up for grabs — as is a $100 bar gift card for best costume of the night. Oct. 27, 4 p.m. to 2 a.m., 1281 Cambridge St., Cambridge, bukoskitavern.net/cambridge-2

Scary clowns never seemed so timely

Indulge your worst nightmares in a really sexy, artsy sort of way when the Boston Circus Guild takes over the OBERON Theatre for five nights of Cirque of the Dead. Sound weird? Well, that’s part of its charm. In its fourth year, the production combines acrobatics, sideshow, burlesque and live music for a celebration of the most macabre monstrosities. They encouragingly advise attendees to dress like a “zombie so the rest of the horde is less likely to eat you.” Oct. 21-29, 2 Arrow St., Cambridge, 18+,  $30-$50, americanrepertorytheater.org

Have a bloody good time

The Rockwell (nee Davis Square Theatre) will present “Thirsty,” a modern day tale of the quest for love on a (chillingly familiar) swipe-able dating app. The romantic comedy tells the story of average single guy Jeremy (non-vampire) and his total babe of a match, Vanessa (probably a vampire) and drama the follows. Oh, and they have a full bar. Win. Oct. 30 at 2 p.m. and 8 p.m., 255 Elm St., Somerville, $18-$20, thirsty2016.bpt.me

Feel good about behaving badly

You can be the most amoral ax murderer on the block with a ticket to Tico’s Halloween bash for the Ellie Fund. The Alice in Wonderland-themed evening (titled “We’re All Mad Here”) will give the full ticket price back to the charity, while you get three drink tickets, snacks, dancing and complimentary air-brushed tattoos all night long. (Cover me in cats, please.) They also promise an authentic Mad Hatter tea party and flamingo croquet on their patio should the weather play nice. Oct. 29, 9 p.m. to 2 a.m., Tico, 222 Berkley St., Boston, $50-$65, ticketbud.com
