I showed my surprise. "No. I came straight here."
"What time did you get here?"
"Just before eight. I had an appointment—with Miss Hendricks."
"Yeah?" He whirled toward Laurie. "And what time did you get here?"
"It was five minutes past eight, Sergeant," she lied calmly. "I know because I was a few minutes late and I checked my watch."
The sergeant glared at her suspiciously, then swung back to me. "You've been here since then? The two of you?"
"That's right," I said, wondering at the smoothness of Laurie's lie. "Now maybe you'll tell me what this has to do with—Miss Worthington."
His small hard eyes snapped with something like pleasure. "She was murdered, professor. That's all."
I felt the blood drain from my face. "Murdered?"
"Yeah. We figure between eight and eight-thirty, closer to eight. That's nice timing for you, professor. Seems like the girl had a helluva lot of boyfriends—but you were number one on our list!"
