Mr. Fisk made his way down the street, avoiding everyone he could. The buildings loomed over the street, casting a shadow that crept slowly forward as the day went on. The shadow had a repelling effect on pedestrians, and space on the sidewalk grew ever more sparse as it advanced.
Fisk was unaware of all this, his mind rooted to events two days in the past, events which had caused a cancerous fear to grow inside him. His eyes grew yellow and the skin around them grew dark, and though he had had no rest, he did not feel tired, but numb. He had been walking haphazardly in the general direction of his apartment when he came across a brightly lit-building, the city aquarium. Like a moth, he was powerfully attracted to it and found himself pushing open the doors and going inside.
He had not slept since the mugging. He still remembered the exact alley from which the predator had come. The mugger had been armed with a knife, and Fisk had frozen upon seeing it, unconsciously handing the man all his money without a sound. He walked home a different way the next day.
Inside, the building was a single hallway. The left side of the hallway contained the exhibits, enormous illuminated tanks. The tanks were large enough to afford the animals the luxury of privacy from the often large crowds of people on the other side of the glass.
Fisk went down the hallway, regarding the various species of marine life with indifference, until he came across a particularly dense crowd of people. He saw that they were in front of the shark tank, and were waiting for the monster to show itself. Fisk mused at how sad it was that such a great animal was captive. And suddenly, it was there, with only a few inches of glass separating everyone from the beast. Fisk held his breath. The shark seemed to be looking directly at him with its cold eyes. It bared its teeth at him, forming a sinister but knowing grin. People jostled past him in the narrow hallway.
Fisk stood there for a long time, even after the shark had gone, its smile burned into his mind. After while he walked out of the dark hallway, into the fading light of the city, and quickly made his way back home, to avoid being out past dark.
Fisk wandered around his apartment without direction for a while. His windows and doors were locked. He stopped in front of a window and leaned on it with his hand while he peered out. It was old and stained, and it allowed only a small amount of light into the apartment. Fisk could feel the cold of the night through the glass surface.
He went on living in this manner for two weeks, when he saw the shark's picture in he paper. One of the aquarium's employees had fallen into the tank, and the shark had claimed the man's hand as a result.
That night, Fisk paced back and forth in his apartment. He opened his windows and stuck his head out, looking at the sky. The crescent moon hung amidst the stars, looking like a saber. He put on his coat and left the building.
Fisk made his way deliberately back to the alley he remembered so well. The same mugger as before jumped out of the alley, knife at hand. He sneered, remembering his old victim. Fisk regarded him coldly, his eyes focused on the mugger's throat. Fisk bared his teeth. The shark struck.
