“The Curious Incident of the Dog in the Night-Time” is in the final week of its run at the Ellie Caulkins Opera House, 1385 Curtis St.

Adapted from Mark Haddon’s best-selling novel and winner of five 2015 Tony Awards including Best Play, “Curious Incident” tells the story of Christopher Boone, an exceptionally smart, autistic 15-year-old who makes a life-changing discovery while trying to find out who killed his neighbor’s dog.

Tonight’s performance is at 7:30 p.m. and tickets are $30-$105.

It’s Ignite Night at History Colorado, 1200 Broadway, and this month they’ll be exploring duels — dueling madams, dueling guitars, dueling games and more — through live music, theater, conversation, demonstrations, crafts and exhibition tours.

It lasts from 5 to 8 p.m. and tickets are $10-12.

Over at Ophelia’s Electric Soapbox, 1215 20th St., it’s time for another round of ’90s sitcoms and TV dinners. As always, they’ll be serving up an $18 three-course meal — vegetables, meat and dessert — with Zima and wine coolers.

It starts at 5 p.m.
