Oh, the things we could get away with in the days before cell phones and social media – or at least thought we could get away with.

Belfry Theatre presents “How the Other Half Loves,” the American version of a popular British farce by Alan Ayckbourn. In this play, we are presented with two couples in decaying marriages. In fact, one of the husbands is in an affair with the other’s wife. When pressed for an alibi, the guilty individuals name a boring couple they barely know, who then get entangled in the ensuing mess.

The production is also a study in contrasts. The Fosters, Frank (Tim Long) and Fiona (Susan Hill) are wealthy, while the home of Frank’s employee Bob Phillips (Ronan Marra Sr.) and his wife Terri (Sarah Froehlke) is more modest and cluttered with items from caring for their baby Benjamin (sound effect and bundle in a “portapram”). These homes are presented simultaneously, with both sets of living room furniture present, and the walls sectioned for a lenticular effect. Kudos to director Nicole Amsler and set designer and builder Julia French for the excellent stage, with perfect spacing and visual cues to help pull off the desired effect.

Set in 1972, the story begins on a Thursday morning, after both Bob and Fiona had been out until the wee hours – with each other. To cover, Bob tells Terri he spent the night reassuring William Detweiler (Ken Kingshill) who suspects his wife is having an affair. In turn, Fiona tells Frank she was out reassuring Mary Detweiler (Lisa Warner) who suspects her husband is having an affair.

These stories are soon tested as Frank announces that William is joining Bob’s work team and that the Detweilers are coming over for dinner that night. Meanwhile, Terri arranges for a dinner with the couple on Friday (to “help” and to give the harried homebound mom more adults to talk to). Thus Ayckbourn’s script gets particularly inventive, as the two intimate dinner parties at two locations on two nights are presented simultaneously, involving a couple of rather bewildered Detweilers.

This is going to be one wild weekend.

Long gives us an interesting character in Frank, who comes off as a bit scatterbrained (almost worrisome at times) but eventually picking up on the clues – though not necessarily the right ones. Hill’s Fiona is detached and jaded, yet entertaining in her own acerbic way. Marra’s Bob is a cad – sorta likable, but still an ass – the kind of person who gets away with little, yet more than he should. It helps that Froehlke has amiable but frustrated Terri keep at least a degree of love and grace for him, even when he’s at his worst. Kingshill and Warner present an eccentric introverted couple whose relationship seems to have reddish flags of its own, but are well suited to each other.

The outfits they all wear are appropriate to the period, especially Froehlke’s, which could only be described as “groovy.” Compliments to costumer Sue Kuehnhold. Desiree Black is stage manager.

Constant comic confusion and mild slapstick generate laughs throughout, though seeing this work of a prior generation from the perspective of today’s awareness of disorders and dysfunctional relationships did temper my response. There’s even a brief bit of angry violence. This is very much an artifact of its time, the kind of wacky show you’d see after watching “Laugh-In.” Taken in that context, this time capsule works splendidly.

Performances run through Sunday, Oct. 1, at Arts for Lawrence’s Theater at the Fort, 8920 Otis Ave. For info and tickets visit thebelfrytheatre.com or artsforlawrence.org.
