"I believe you."

"But how could a key show numbers that don't exist?"

His mouth pulled down again and he shrugged. "It was probably a duplicate."

"What difference would that make?"

He reached in his pocket and pulled out a loose key. "This is the key for a padlock back there. On this side is the manufacturer, a Master padlock in this case, like the key we're discussing. Did it look like this?"

"More or less," I said.

Helen had lost interest. She'd moved over to one of the free-standing safes, where she was perched wearily, leaning on her bat like a cane.

"Okay. This side says Master, right?"

"Right."

"On this side, you got numbers corresponding to the particular padlock the key fits. Are you following?" He looked from me to Ray, and both of us nodded like bobbleheads.

"You give me those numbers, I can look 'em up in this index and get the information I need to reproduce this key, making you a duplicate. But the duplicate isn't going to have the numbers. The duplicate's going to be a blank."

"Okay," I said, drawing the word out cautiously. I couldn't think where he meant to go with this.

"Okay. So the numbers you saw must have been stamped after the key was made."

I pointed to the scratch pad. "You're saying someone had those numbers put on this key," I said, restating it.

"Right," he said.

"But why would somebody do that?" I asked.

"Lady, you came to me. I didn't come to you," he said. When he smiled, I could see the discoloration in his teeth, dark around the gums. "Those numbers are gibberish if you're talking about a Master padlock."

"Could they be code numbers for another key manufacturer?"

"Possibly."

"So if we figured out which manufacturer, couldn't you make me this key?"

"Of course," he said. "The problem is, there's probably fifty manufacturers. You'd have to go through two, three manuals for each company, and many I don't stock. Stamped numbers or letters might also identify the key with a property or door, but there's no way to determine that from what you're telling me."

"Have you ever heard of a Lawless lock?"

He shook his head. "No such thing."

"What makes you so sure?" I said, irritated by his know-it-all attitude.

"My father owned this company and his father before him. We been in business over seventy-five years. If there'd been such a company, I'd have heard the name mentioned. It might be foreign."

I made a face, knowing there'd be no way to track that down. "Is there any chance whatsoever that Lawless was in business back in the forties and is now defunct?"

"Nope."

Ray put a hand on my arm. "Let's get out of here. It's okay. We're doing this by process of elimination."

"Just wait," I said.

"No way. You got a look on your face like you're about to bite the guy." He turned to his mother, "Hey, Ma. We're going now." He helped her to her feet, taking her arm on his right while he took my arm on his left. The pressure he exerted made his intentions clear. We were not going to stay and argue with a man who knew more than we did.

I felt my frustration rise. "There has to be some connection. I know I'm right."

"Don't worry about being right. Let's worry about getting Gilbert off our backs," he said. And then to Reidel, "Thanks for your help." He opened the door and ushered us out. "Besides, we don't need the key. Gilbert's got one."

"Well, he's not going to give it back."

"He might. If we can find the locks, he might cooperate. It'd be in his best interests."

"But what are the numbers for? I mean, M550 has to be a code, doesn't it? If not for a key, then something else."

"Quit worrying," he said.

"I do worry. Gilbert's going to want answers. You said so yourself."

Out on the street, it was surprisingly dark. The late afternoon wind whipped off the Ohio River, which I gathered was only three or four blocks away. A few isolated snowflakes sailed by. Streetlights had come on. Most of the businesses along Main were closing down, and building after building showed a blank face. The buildings were largely brick, five and six stories high, the ornamentation suggesting vintage architecture. Several ground-level stores had retracting metal gates now padlocked across the front. An occasional dim light might be visible deep in the interior, but for the most part, a chilling dark contributed to the overall look of abandonment along the street. Traffic in this part of town was thinning. The downtown itself, visible to the east, displayed a lighted skyline of twenty- to thirty-story office buildings.
