I continued around the big bend in the road and took a right at the next light, turning onto the street that fronted the zoo, which was closed for the day, its entrance barred by a gate with a wooden arm. The parking lot was empty, and even at a distance I could see the wrought iron gates were locked. The turnstiles behind them were in shadow.

Felix leaned forward, arms on the front seat, talking into my right ear. “Keep on this road around to Milagro.”

I did as instructed, wondering if this was how a bank robber felt when he’d been assigned to drive the getaway car. There was a produce market on the corner a couple of blocks farther on. It was open for business seven days a week with an expansive parking lot on the far side. I’d passed the market any number of times. I’d even shopped there on occasion, impressed by the lavish displays of fresh fruits and vegetables. I caught the scent of celery as I drove by—I swear I can smell celery half a block away—and wished I were eating a bowl of homemade vegetable soup instead of being cooped up with a homeless pair who reeked of cigarettes. I turned right onto Milagro and then right again into the parking lot.

The Union Pacific rail lines run between the highway and the periphery of the lot, which was topped with a mix of gravel and asphalt. There were ten or twelve cars parked close to the market, but the remainder of the lot was empty. I drove to the far end, where I could see the pavement shrink to a narrow road that snaked upward and out of sight. I followed the road. The hill rose gradually with trees on either side forming a canopy overhead. The roadbed was not quite wide enough for two cars to pass, but I didn’t picture much in the way of traffic.

I kept my speed to a minimum as I trundled along the lane. I was driving maybe two miles an hour, noting the backside of the zoo structures as they appeared to my right. It was odd to see the facility from this perspective. Where the public areas were defined by walkways that wound among the animal enclosures, the hinterland was all business: garages and storage sheds; lengths of fence that could be moved and bolted into place where needed; service trucks, fork lifts, and utility vehicles; artificial jungle plants and fake boulders that could be called into use to create the illusion of the wilds. As a child, I’d ridden on the narrow-gauge kiddie train that circled the property, so I’d seen glimpses of the same inner workings.

I let Pearl direct me to a spot along the fence she said was closest to the camp.

“You better turn the car around in case we have to get out in a hurry.”

“What hurry? The guys are gone,” I said.

“But supposing they come back is all I’m trying to say.”

Oh great, I thought. I would have liked a place to pee, but it was too late for that and the urge was probably only a manifestation of a creeping attack of nerves. There was scant turning-around room available. I only succeeded by constantly backing up and inching forward, with Felix standing where I could see him in the rear- and side-view mirrors making hand gestures to signal left, right, and stop. Give the fellow an orange plastic baton and he could have offered the same guidance to an airline pilot arriving at the gate.

When I’d completed the 180-degree reorientation, I pulled on the emergency brake, killed the engine, and got out. The fence was a heavy-duty chain link with poles buried in concrete containers at ten-foot intervals. Someone had used cable cutters to open a seam that ran up along the side of one pole. The section of fencing was still bent upward where it had been pressed into use. Right away I thought about that high school geometry concept I never imagined would serve me in real life. The pole and the ground formed a right angle, with the hypotenuse measuring a lean thirty-six inches. Pearl was wider than a yardstick and I wasn’t sure how she’d manage to condense her girth sufficiently to fit through the gap. However, this invasion was her big hot idea and I wasn’t about to volunteer to take her place.

It looked like the emergency exit hadn’t been used for some time. The weeds were thick and the ground underfoot was spongy, a natural mulch of decomposing leaves and bark. The smell suggested decay, not of flesh but of plant material. Felix and I pulled up the stiff triangle of fencing while Pearl got down on her hands and knees and then lowered herself on her stomach. Being prone didn’t seem to make her smaller or more compact. Pearl’s fake leather jacket added mass to her already bulky frame. The raw cut tines of chain link formed a crooked line. Some of the tines pointed down and some upward, like the traffic teeth at a parking lot exit, intended to discourage you from changing your mind and backing up.

Felix said, “Whyn’t you take your jacket off?”
