I found myself at the Gotham City Zoo, which was closed for today. I ignored the weekly schedule and jumped the fence, landing softly on the concrete ground behind it.
I need to hurry, I thought. After sunset, I won't be able to see well.
I followed the icy trail, which led me to the polar bear exhibit. I pressed my face to the cold glass, waiting to find a hint of Mr. Freeze.
Nothing. All I could see was the clear, blue water. I was hoping for one of his bears to swim by, but I was also afraid of being seen.
I looked up. The tank was open at the top, but going in the water meant risking my life. I found a landing and climbed it, leaping off the edge of the tank and plunging into the water.
The frost bit at my uncovered skin, leaving my limbs numb and limp. Instinctively, I pressed my arms to my torso, trying to gather all the warmth I could get.
Great job, Erica. Now Batman's sure to make me work all night!
I cautiously stretched out an arm and pulled my body to the surface. I was half-freezing when I pulled myself out of the water, and fell to the concrete zoo floor.
The pain of my landing barely hurt--it was the cold I was worrying about. Suddenly, I heard a beeping noise from the inside of my pocket.
I pulled out my communicator and stuck it to my ear. "H-hello?"
"Did you get him?" asked a recovering Robin.
"N-no, I l-lost him." Usually I'd be embarrassed, but I didn't have enough heat inside me to blush.
"What's wrong? Did he freeze you?" he sounded worried.
"N-no. I was just being s-stupid. See you back at b-base."
I hung up, and rocked back and forth, clutching my body close together. I found a towel hanging nearby, and wrapped it around myself. I decided not to use the Bat rope, for the air would just make me even cooler.
I jumped the fence again, and started walking toward the telephone booth. I passed Gotham Labs, which was a laboratory that tested on unhopeful causes.
I peered inside one of the windows, wondering what they were testing in there. Two scientists in white labcoats were taking notes on something.
Quietly, I stepped inside, careful not to make any noise. And then I saw it.
A blonde woman was in a large glass tube filled with water, and that could only mean one thing.
This was what Mr. Freeze was after, but he just couldn't find it. Nora Fries, his wife.

I pulled a Batarang from my belt and threw it at the glass.
