MAIL ME THE TROUBLE TICKET.

There’s a musical ding from over by the doorway, and a mail icon appears on your desktop.

ON DUTY, you send, giving the latte a final wistful look. “Bob? We’ve got a call.”

“Eh, boss…?” Bob lifts his cup and hides whatever he’s been working on—probably Solitaire.

“Bring it along, it’s nae the blues.”

You file the email as you leave the coffee shop. Bob trails after you. The destination shows up, as a twirling diamond just visible over the buildings on the far side of the road as you get in the car.

It’s a short drive from Corstorphine to the incident site, but it’s up the steep slope of Drum Brae, hemmed in by shoe-box houses at the bottom of the hill and the whirring prayer wheels of the wind farm at the top. By the time you’re heading downhill again, you’re worrying that the map is confused: “Turn right in one hundred metres” it tells you, but all you can see is an urban biodiversity coppice. “What’s the scene?” asks Bob.

“I dinna ken. The skipper says it’s a weird one.” You feel a flash of irritation—but your shift is a car short today, which makes it a stupid time for a prank—and right then you spot an open driveway leading into the trees, and your specs are flashing green. “Eh, look at that lot, will you?”

There are a bunch of cars parked at the end of the drive, and as the Forestry Commission doesn’t hand out Bentleys and Maseratis, it’s a fair bet that you’re in the right place. But the building they’re parked outside of is a raw contrast to the posh wheels: It’s more like a 1950s public toilet than a corporate office, just four concrete walls propping up a flat slab of characterless roof that seems to scream Asbestos! with all the force its wheezing, mesothelioma-ridden lungs can muster. Maybe it’s some kind of up-market cottaging club for the tech start-up crowd? You shake your head and climb out of the car, tapping your ear-piece to tell your phone to listen up: “Arriving on SOC, time-stamp now.
