The house on 12 Street.

For twelve years, the house at 1827 12 Street SW had the most ambitious Halloween yard in Calgary. For one year, it nearly cost the family their home.

The shadow over the block.

I should explain. The house at 1827 12 Street is — was — the project of a man named Doug Markham. Doug was a costume designer for Theatre Calgary in the 1990s. He retired in 2009. His wife had passed in 2007 from a long illness. The kids were grown.

Doug, alone in the house, started building Halloween installations. Not the off-the-shelf inflatable graveyard. We're talking about scenes. A graveyard with animatronics that he'd built himself, hooked up to motion sensors. A werewolf-transformation tableau in the side yard. A cellar window with a glowing red light and the recorded sound of breathing.

The first year — 2009 — it was just the front yard. By 2012 it spilled onto the boulevard. By 2014, Doug had recruited two neighbour kids to act as ghouls in costumes he'd made. The kids stood near the gate and were paid — ten dollars per shift, plus pizza — to slowly reach for the trick-or-treaters.

The block, by 2015, was famous in Calgary. People drove from Beddington to see it. The line of trick-or-treaters wrapped around the corner onto 18 Avenue. Doug's annual setup costs, paid out of pocket, ran into the thousands. He didn't take donations. He didn't charge. He did it because, his neighbours all suspected without saying so, his wife had loved Halloween and he had not stopped loving her.

The peak.

2018 was the height. Doug had built — that year — a haunted Edwardian dollhouse in the front window. The dollhouse was scaled-down: actual rooms, actual lights, actual tiny moving figures. He had spent six months in his garage. The kids on the block — by then, dozens of us — had each been assigned a role. Some of us were ghouls. Some of us were "guides" who walked smaller kids through the experience. I was 14. I was, if we're honest, a slightly mediocre ghoul.

That year, an estimated 800 trick-or-treaters came through. The CBC sent a photographer. The Herald ran a profile. Doug, in the profile, said: "It's just a way to keep occupied. The wife liked Halloween." He did not elaborate. He did not need to.

For seven years, this was the unambiguous joy of the block. Old neighbours, new neighbours, Doug-with-his-wife-photo-still-on-the-mantel, kids in costumes, parents with thermoses of hot chocolate, a community that had built, around one widower's grief, the best Halloween tradition in Calgary. That's important to remember as we get to the next part.

The arrival of the monster.

October 2020. COVID. Restrictions. No public gatherings. Trick-or-treating allowed only with distancing protocols.

Doug, 71 by then, had spent the spring grieving his old habits. He had told my mother, on a socially-distanced front-yard visit in August, that he wasn't going to do the installation that year. "It wouldn't be fair," he said.

The block was disappointed but understood. The 2020 Halloween was quiet. The 2021 Halloween was modestly more open but Doug, still, did not return to full setup. He lit the front yard with lanterns and gave out pre-bagged candy. The whole thing felt held in suspension, like the block was waiting for a return.

The return came in 2022. Doug went bigger than he ever had. He had been writing, planning, and building for two years. The 2022 setup included a full-scale Edwardian séance room visible through the front window, with three life-size figures and, somehow, real candles in glass cases. The line that year wrapped around two blocks.

This is where the monster arrived.

One of the new neighbours — three doors down, moved in 2021 — filed a complaint with the City of Calgary about the line, the noise, and the safety implications of "live flame" in the display. The neighbour cited bylaws around fire risk, occupancy of public boulevards, and noise ordinance after 9 PM. The City, in late November 2022, opened a file.

The neighbour, in detail.

I will not name him. He is a man, my age now (24), who works in tech and bought the house at the height of the post-pandemic Calgary market. He had three concerns, in his telling, all defensible: the candles were a fire hazard, the crowds blocked his driveway during peak trick-or-treat hours, and his small dog became distressed by the recorded sound effects.

None of these concerns is unreasonable in isolation. Each is a matter that any reasonable neighbour might raise. The combination — and the formal complaint to the City — was, in the eyes of the rest of the block, a kind of declaration of war.

The block was, briefly, divided. About 60% of the block thought the new neighbour was being unreasonable. About 30% thought he had a point about the candles. About 10% — including, surprisingly, Doug himself — thought the conversation was overdue and that some accommodations should be made.

The monster wasn't the new neighbour. The monster was the slow accumulation of unspoken disagreement that eventually had to be voiced.

The fight.

This is where the Booker plot starts to do its work.

Most "Overcoming the Monster" stories cast the monster as a villain. The villain wears black. The villain has fangs. The villain wants to eat the village. In real life, especially in Calgary in 2022, the monster was something different. It was the slow accumulation of small unspoken disagreements that, when finally voiced, could not be put back.

Doug's response, when the City notice arrived in late November, was — characteristically — quiet. He did not get angry. He did not file a counter-complaint. He went to the new neighbour's house and rang the doorbell. The new neighbour answered. They sat on the front porch for forty-five minutes. I don't know what was said because I wasn't there. My mother, who watched from across the street, said the body language was respectful.

What came out of the conversation:

• Doug agreed to switch the candles to LED imitations starting the following Halloween (he had been thinking about this anyway, for cost reasons).
• Doug agreed to set the audio system to auto-mute after 8:30 PM.
• The neighbour agreed to drop the City complaint.
• The neighbour agreed to be on the block's volunteer list for the 2023 setup, on the condition that Doug taught him how to wire the animatronics.

The last point is the one that matters.

The resolution.

Halloween 2023 happened. The Edwardian séance room came back, with LED candles. The audio system went silent at 8:30 PM. The new neighbour — the man who had filed the complaint — was, for two weeks in October, in Doug's garage with him, learning how the motion-sensor circuit boards worked.

I was 21 by then. I was studying costume design at the University of Calgary, partly because of Doug. I came home for the Halloween weekend. I watched the new neighbour, in a half-finished costume that Doug had clearly helped him with, hand out candy at the gate. He was, I think, slightly embarrassed and slightly proud. The dog was inside the house. The crowds were the same as ever.

The monster — the real one, the one underneath — had been the absence of a conversation. The conversation had happened. The block was, by Halloween 2023, more itself than it had been since 2019.

The aftermath.

Doug passed in February 2025. He was 74. The house at 1827 12 Street is now — tentatively — being maintained as a Halloween-installation house by a small group of neighbours, including the man who filed the original complaint. The 2025 setup was smaller and slightly more conventional than Doug's would have been. The 2026 setup, planned for this October, includes a small plaque on the front gate that reads: For Doug Markham, who built it. For Margaret Markham, who taught him to.

The block has agreed, by silent consensus, that the installation will continue as long as anyone has the energy to build it.

What we learned.

The monster, in Booker's framework, is rarely a person. It is the thing the community is held by — the unspoken disagreement, the deferred conversation, the structure that everyone has agreed to live inside. Confronting the monster is rarely about defeating an enemy. It is usually about having the conversation that was overdue.

The 12 Street block had its conversation. The block came out the other side stronger. Doug came out the other side, briefly, with a friend he hadn't expected to make. Halloween came out the other side as a tradition that now belongs to the block as a whole, rather than to one widower with a garage full of animatronics and a wife on the mantel.

If you have a Calgary Halloween memory — a haunted-house memory, a costume memory, a chinook-night memory, a memory of the first time your neighbourhood did something together — file it on the wall. The wall keeps them. The next 14-year-old being a slightly mediocre ghoul on the next 12 Street will need to know.
