Act I: The Alley Behind Sunset Boulevard

Jack Moran found the rattlesnake in an alley behind Sunset Boulevard on a Tuesday in March 1947. He wasn't looking for it—he was looking for a bottle of whiskey he'd dropped the night before, and he found it instead. The snake was coiled on a piece of rotting wood, its rattle silent, its golden eyes fixed on Jack with the kind of attention that made him uncomfortable.

He'd spent six years in the ring before his knees gave out, and six years after that trying to forget what it felt like to be hit in the face with enough force to make your ancestors apologize. He'd become a private detective out of boredom, mostly tracking cheating husbands and missing wives, the kind of work that paid enough to keep him drinking but not enough to keep him sober.

He should have killed the snake. That's what you do with a rattlesnake in Los Angeles—you kill it, because it's your legal and moral duty to kill every rattlesnake you see. But Jack didn't kill it. He looked at it for a long time, thinking about how the snake was coiled, how its body was tense but not aggressive, how it was ready to strike but hadn't struck yet, and he saw something in that coiled readiness that he recognized.

He'd been coiled like that for six years.

He walked away. He came back the next day with a piece of bread. The snake didn't eat it. Snakes don't eat bread. But Jack left it anyway, and he came back the next day, and the next, until six months had passed and the snake had grown larger and Jack had developed a habit he couldn't explain.

Act II: Lucy Valentine

She showed up at his office three months after he'd first seen the snake. Jack was sitting at his desk, staring at a wall that needed painting, when the door opened and a woman walked in who looked like she'd been designed by a man who'd only heard descriptions of beautiful women and had tried to build one from the specifications.

She was tall, dark-haired, with eyes that didn't blink enough and a smile that was all teeth and no warmth. She wore a red dress that cost more than Jack's car and carried a purse that probably cost more than his desk.

"Mr. Moran?" she said. Her voice was low and smoky, the kind of voice that made men lean forward without knowing why.

"That depends," Jack said. "Are you here to collect or to pay?"

"I owe you a favour," she said. "I know you don't remember me, but I remember you. Six months ago, in an alley behind Sunset Boulevard. You saw a snake and you didn't kill it. That makes you either the bravest man in Los Angeles or the stupidest. I decided to find out which."

Jack felt a cold sensation move up his spine. "What do you want?"

"I can help you," she said. "With your cases. I know things. I know where people are, what they've done, who they're afraid of. I can help you solve cases that other detectives can't. And in return, you protect me."

"Protect you from what?"

She smiled, and this time it reached her eyes, and for a moment Jack saw something in them that wasn't calculation or desire or anything he recognized. It was fear. Ancient, deep, and absolute.

"From the things that want to use me," she said.

She was good. Better than good. In the three weeks that followed, she helped Jack solve three cases that had been stalling for months. She found a missing wife in a motel in San Diego by calling every phone book in the city and cross-referencing the names with a list of men who'd written to her. She recovered stolen documents from a safe in a downtown office building by talking to the guard until he told her where it was. She intimidated a witness into changing his testimony by sitting across from him in a diner and describing, in precise detail, the exact way his wife would look if something happened to her.

Every time she helped, there was a price. Not money—something else. A favour in return. A secret she wanted him to know. A name she wanted him to remember.

Jack didn't ask what she was. He'd learned in the ring that some things you don't ask about. You just know.

Act III: The Old Man's Choice

Sal Maroni was what Los Angeles called a "businessman." He owned three nightclubs, a union local, and enough politicians to make sure the police never looked too closely at what happened behind the closed doors of his establishments. He was fifty years old, fat, and bored, and he had decided that Lucy Valentine was something he wanted.

He called Jack into his office on a Thursday afternoon. The office was on the fourth floor of a building on Spring Street, all marble and gold leaf and the smell of expensive cigars. Sal sat behind a desk that cost more than Jack's annual income, and he smiled the smile of a man who had never been told no.

"Moran," he said. "Lucy's been helping you."

"That's right."

"She's very useful. But she's also mine. I've been using her for things you don't know about. Things that require... special skills. She's been working behind my back, and that makes me angry."

Jack felt his hands clench into fists. "What do you want?"

Sal leaned forward. "I want you to make a choice. Hand over Lucy and everything she knows about the venom she extracts, and I'll let you walk out of this office alive. Refuse, and I'll make sure you never walk again."

"The venom?" Jack said.

Sal's smile widened. "You didn't know? Lucy extracts venom from rattlesnakes. Rare venom. The kind that makes people see things that aren't there. The kind that rich men pay fortunes for. The kind that I've been selling to the doctors at the psychiatric hospitals as a treatment for nervous conditions."

Jack stood up. He was a big man when he wanted to be, and right now he wanted to be. "You're sick."

"I'm a businessman," Sal corrected. "There's a difference. Now make your choice."

Jack made a third choice. He walked out of the office, went to his car, and drove to Lucy's apartment. He told her everything. She listened without expression, her golden eyes fixed on something beyond the walls of her living room.

"I know," she said when he finished. "I've always known."

"Come with me," Jack said. "We can leave. Go to Mexico. Start over."

She shook her head. "I can't leave. I'm needed."

"Needed by who?"

She didn't answer. She just looked at him with those golden eyes, and he knew that whatever she was, whatever she was connected to, it was older and deeper and more powerful than anything Sal Maroni or Jack Moran or any man in Los Angeles could understand.

He drove to the warehouse in the industrial district where she kept her snakes. He locked the doors from the outside. He got in his car and drove to the bus station. He bought a ticket to Mexico.

He didn't look back.

Act IV: The Fire

The warehouse fire happened three days later. Jack heard it on the radio while he was sitting in a bar in Tijuana, drinking tequila and trying to forget the look in Lucy's eyes.

"A devastating fire destroyed a warehouse in the industrial district last night," the announcer said. "Fire officials report that a woman was found dead inside, along with several snakes. The cause of the fire is under investigation."

Jack poured his tequila onto the bar. He stood up, walked out of the bar, and walked until he found the beach. He sat on the sand and watched the sun go down over the Pacific and thought about Lucy and the way she'd looked at him, and he wondered if he'd made the right choice.

He never found out. He spent the rest of his life in Mexico, drinking tequila and staring at the ocean and wondering if the woman he'd locked in a warehouse with a bunch of rattlesnakes had been human or something else, and whether locking the doors had been an act of courage or cowardice.

The venom never worked the way Lucy said it would. It just made people see what they already knew.

And that was worse.
