If you were a certain kind of person with a certain kind of schedule in the early sixties, you probably saw a show that some friends of mine and I worked on called Acres of Perhaps. By “certain kind of person,” I mean insomniac or alcoholic; by “certain kind of schedule,” I mean awake at 11:30 at night with only your flickering gray-eyed television for company. With any luck, it left you feeling that however weird your life was, it could always be weirder.

The first time the wrens sang at night was three years ago, when I used a rusty saw to cut off Pa’s left foot. The birds drowned out his screams. Wrens don’t normally sing after sunset, but I wasn’t surprised by it. Birds are known as spirit carriers in mountain lore. When someone dies, birds of all kinds carry them back and forth between this world and the afterlife, so folk can keep watch over their living loved ones, even after they’re gone.

When Claudia’s six-year-old daughter Jane disappeared, Claudia was making love to a man who was not her husband. All her life she’d made mistakes and here was one more, worse than the others. This was in the house of Jane’s friend Magda. Magda and Jane were downstairs playing an aggressive doll game they’d invented; Claudia and Magda’s father were in the guest bedroom. He’d steered Claudia away from the master bedroom, the way he might any old house guest on a tour of the upstairs.

I was walking to my car from San Francisco’s 22nd Street Train Station when I first saw the old man. He was on the wrong side of the chain-link fence that separated the sidewalk from the steep rocky slope that led down to the train tracks. The station was an asphalt platform beside the train tracks, set at the bottom of a ravine. Steps from the platform led up to the street, but no steps led where the old man was walking. The only way to reach that particular spot was to climb a six-foot concrete block wall.

Vocations don’t grant vacations. I’m supposedly on holiday in London when I get an offer no reporter could refuse: to see a unicorn in the wild. I’m with my friend Samantha, hanging out at her Dad’s pub after a long night’s clubbing, still wearing our dance-rumpled dresses, dying to get out of our heels. Sam’s father, Will, is tending bar tonight, so it’s the perfect spot for late-night chips and hair-of-the-dog nightcaps. Plus, most of the clientele is over fifty. We wouldn’t have to spend all evening judo-throwing chirpsers.

The Weialalaleia (Hirudo Threnophaga) is difficult to observe, and is more recognisable by the sound that accompanies its presence than by its shape. It floats on the air like a jellyfish in water, and, like a jellyfish, is translucent, although there is some debate within cryptohirudological circles about whether the Weialalaleia lacks pigment.
