"What happened when you got home?" I asked.
"Nothing. Everybody was asleep," he said. "We have something in the lab you might want to see." He moved down the hall to the right and I followed. He looked back at me. "Feldman had the guys check the trash bins at your suggestion. We think we found the silencer."
"You did?" I said, startled.
He opened the half-door into the crime lab, holding it for me as I passed in front of him. The lab tech was out, but I could see Billy's bloody shirt, tagged, on the counter, along with an object I couldn't at first identify.
"What's that," I said. "Is that it?" What I was looking at was a large plastic soft drink bottle, painted black, lying on its side with a hole visible in the bottom.
"A disposable silencer. Handmade. A sound suppressor, in effect. It's been wiped clean of prints," Jonah said.
"I don't understand how it works."
"I had to have Krueger explain it to me. The bottle's filled with rags. Take a look. The barrel of the gun is usually wrapped with tape and the bottle affixed to it with a one-inch hose clamp. The soda bottle has a reinforced bottom, but it's only effective for a few shots because the noise level increases each time as the exit hole gets larger. Obviously, the device works best at close range."
"God, Jonah. How do people know about these things? I never heard of it."
He picked up a paperbound booklet from the counter behind me, flipping through it carelessly so I could see. Every page was filled with diagrams and photographs, illustrating how disposable silencers could be made out of common household objects. "This is from a gun shop down in Los Angeles," he said. "You ought to see what you can do with a length of window screen or a pile of old bottle caps."
"Jesus."
Lieutenant Becker stuck his head in the door. "Line one for you," he said to Jonah and then disappeared. Jonah glanced at the lab phone, but the call hadn't been transferred.
"Let me take this and I'll be right back," Jonah said. "Hang on."
"Right," I murmured. I leaned toward the silencer, trying to remember where I'd seen something similar. Through the hole in the bottom, I caught a glimpse of the blue terrycloth filling the interior. When I realized what it was, my mental process clicked in, and the interior machinery fired up. I knew.
I straightened up and crossed to the door, checking the corridor, which was empty. I headed for my car. I could still see Ramona Westfall coming up the basement stairs with an armload of ragged blue bath towels, which she'd dumped on the chair. The plastic bottle had been filled with a soft drink which she nearly dropped as she passed it to Tony to refrigerate.
I stopped by the office long enough to try the Westfall's number. The phone rang four times and then the machine clicked in.
"Hello. This is Ramona Westfall. Neither Ferrin nor I can come to the phone right now, but if you'll leave your name, telephone number, and a brief message, we'll get back to you as soon as possible. Thank you." I hung up at the sound of the tone.
I checked my watch. It was 4:45. I had no idea where Ramona was, but Tony had a 5:00 appointment just a few blocks away. If I could intercept him, I could lean on him some about her alibi since he represented the only confirmation she had. How had she pulled it off? He had to be on heavy medication for the migraine, so she might have slipped out while he was sleeping, adjusting the kitchen clock when she got back so she'd be covered for the time of Daggett's death. Once she was home again, Tony had wakened-she'd probably made sure of that so she'd have someone to corroborate the time. She'd fixed the sandwiches, chatting pleasantly while he ate, and as soon as he went back to bed, she changed the clock again. Or maybe it wasn't even as complicated as that. Maybe the watch Daggett wore had been set for 2:37 and then submerged. She could have killed him earlier and been home by 2:00. Tony may have realized what she'd done and tried to shield her when he understood how close my investigation was bringing me. It was also possible that he was in cahoots with her, but I hoped that wasn't the case.
I locked my office and went down the front stairs, trotting up State Street on foot. The Granger Building was only three blocks up and it made more sense than hopping in my car and driving all the way around to the parking lot behind the building. Tony might still be hanging out at the arcade across the street. I had to get him before she had a chance to intercept. I didn't want him going home. She had to realize things were getting hot, especially since I'd shown up at the house with the shoes and skirt. All I needed from him was an indication I was on the right track and then I'd call Feldman. I thought about the Close, which I knew would be gloomy with the gathering twilight. I didn't want to go back there unless I had to.
