It was a strange sight.

The parents at Pirriwee Public had a baffling fondness for costume parties. It wasn’t enough that they should have an ordinary trivia night; she knew from the invitation that some bright spark had decided to make it an “Audrey and Elvis” trivia night, which meant that the women all had to dress up as Audrey Hepburn and the men had to dress up as Elvis Presley. (That was another reason Mrs. Ponder had turned down the invitation. She’d always abhorred costume parties.) It seemed that the most popular rendition of Audrey Hepburn was the Breakfast at Tiffany’s look. All the women were wearing long black dresses, white gloves and pearl chokers. Meanwhile, the men had mostly chosen to pay tribute to the Elvis of the latter years. They were all wearing shiny white jumpsuits, glittery gemstones and plunging necklines. The women looked lovely. The poor men looked perfectly ridiculous.

As Mrs. Ponder watched, one Elvis punched another across the jaw. He staggered back into an Audrey. Two Elvises grabbed him from behind and pulled him away. An Audrey buried her face in her hands and turned aside, as though she couldn’t bear to watch. Someone shouted, “Stop this!”

Indeed. What would your beautiful children think?

“Should I call the police?” wondered Mrs. Ponder out loud, but then she heard the wail of a siren in the distance, at the same time as a woman on the balcony began to scream and scream.

Gabrielle: It wasn’t like it was just the mothers, you know. It wouldn’t have happened without the dads. I guess it started with the mothers. We were the main players, so to speak. The mums. I can’t stand the word “mum.” It’s a frumpy word. “Mom” is better. With an o. It sounds skinnier. We should change to the American spelling. I have body-image issues, by the way. Who doesn’t, right?

Bonnie: It was all just a terrible misunderstanding. People’s feelings got hurt, and then everything just spiraled out of control. The way it does. All conflict can be traced back to someone’s feelings getting hurt, don’t you think? Divorce. World wars. Legal action. Well, maybe not every legal action. Can I offer you an herbal tea?

Stu: I’ll tell you exactly why it happened: Women don’t let things go. Not saying the blokes don’t share part of the blame. But if the girls hadn’t gotten their knickers in a knot . . . And that might sound sexist, but it’s not, it’s just a fact of life. Ask any man—not some new-age, artsy-fartsy, I-wear-moisturizer type, I mean a real man—ask a real man, then he’ll tell you that women are like the Olympic athletes of grudges. You should see my wife in action. And she’s not even the worst of them.

Miss Barnes: Helicopter parents. Before I started at Pirriwee Public, I thought it was an exaggeration, this thing about parents being overly involved with their kids. I mean, my mum and dad loved me, they were, like, interested in me when I was growing up in the nineties, but they weren’t, like, obsessed with me.

Mrs. Lipmann: It’s a tragedy, and deeply regrettable, and we’re all trying to move forward. I have no further comment.

Carol: I blame the Erotic Book Club. But that’s just me.

Jonathan: There was nothing erotic about the Erotic Book Club, I’ll tell you that for free.

Jackie: You know what? I see this as a feminist issue.

Harper: Who said it was a feminist issue? What the heck? I’ll you what started it: the incident at the kindergarten orientation day.

Graeme: My understanding was that it all goes back to the stay-at-home mums battling it out with the career mums. What do they call it? The Mummy Wars. My wife wasn’t involved. She doesn’t have time for that sort of thing.

Thea: You journalists are just loving the French-nanny angle. I heard someone on the radio today talking about the “French maid,” which Juliette was certainly not. Renata had a housekeeper as well. Lucky for some. I have four children, and no staff to help out! Of course, I don’t have a problem per se with working mothers, I just wonder why they bothered having children in the first place.

Melissa: You know what I think got everyone all hot and bothered? The head lice. Oh my gosh, don’t let me get started on the head lice.

Samantha: The head lice? What did that have to do with anything? Who told you that? I bet it was Melissa, right? That poor girl suffered post-traumatic stress disorder after her kids kept getting reinfected. Sorry. It’s not funny. It’s not funny at all.

Detective-Sergeant Adrian Quinlan: Let me be clear: This is not a circus. This is a murder investigation.

Six Months Before the Trivia Night

Forty. Madeline Martha Mackenzie was forty years old today.

“I am forty,” she said out loud as she drove. She drew the word out in slow motion, like a sound effect. “Fooorty.”

She caught the eye of her daughter in the rearview mirror. Chloe grinned and imitated her mother. “I am five. Fiiiive.”

“Forty!” trilled Madeline like an opera singer. “Tra la la la!”

“Five!” trilled Chloe.

Madeline tried a rap version, beating out the rhythm on the steering wheel. “I’m forty, yeah, forty—”

“That’s enough now, Mummy,” said Chloe firmly.

“Sorry,” said Madeline.

She was taking Chloe to her kindergarten—“Let’s Get Kindy Ready!”—orientation. Not that Chloe required any orientation before starting school next January. She was already very firmly oriented at Pirriwee Public. At this morning’s drop-off Chloe had been busy taking charge of her brother, Fred, who was two years older but often seemed younger. “Fred, you forgot to put your book bag in the basket! That’s it. In there. Good boy.”
