STONEHAM, Mass. — In order to successfully break the fourth wall in theater, you must first construct a full room.

That’s what makes farcical, audience-participation comedies so tricky to pull off. Casts are often better at either world-building or audience participation, and it’s less common to be strong at both. Luckily, audiences are very forgiving when they get to be in on the joke.

That may be why the silly whodunnit Shear Madness is one of the longest-running non-musicals in the world. Based on a German play with a similar premise, this slapstick comedy has been making audiences guffaw since its premiere in 1980. A flimsy murder mystery set within a hair salon, the script’s central contrivance is that it allows space for audience members to share clues and question suspects to solve the mystery.

Greater Boston Stage Company’s production of this chestnut was my first time seeing Shear Madness, and I struggled to buy into the first third of the play. While the cast bought into their broad characters and committed to the physical comedy needed, I found myself questioning what decade they were supposed to inhabit. Landline phones and Olivia Newton-John posters mixed with references to Drake Maye and dead cell phones.

Also, there were several killer jokes within the snappy banter that fell flat because some lines felt delivered for rim-shot moments. I wished instead those same lines were played dry and quick to allow the audience to realize the humor more naturally.

And while much of the important action takes place between four and five in the afternoon, the clock on the wall was clearly showing the ten o’clock hour. All this is to say that while I knew the play was not supposed to be Shakespeare, my mind too often wandered.

Most of the production’s peccadillos were forgotten, however, when the lights were raised and we were brought in to take part in some detective-adjacent work.

Joseph Marrella was the able ringleader of this part of the play as the lead detective, Nick O’Brien. His natural delivery and nearly unflappable stage presence reminded me of my favorite high school teachers. With O’Brien taking the lead, the cast listened deeply to each other and worked together to hash out the various theories suggested in a mixture of scripted and improvised dialogue.

Some of this momentum was stripped away, however, when the action downshifted back to script to reveal the true murderer. Alas, here the play jarringly slipped into melodrama.

All in all, this production of Shear Madness was a close shave at times, it but ended up leaving its audience with the fun feeling of a good blowout: unsubstantial, but a lot of fun in the short term.
