Free D Is for Deadbeat by Sue Grafton

returned to her front door.
    I knocked again. I could see her peer into the hallway from the rear of the house and then approach the front door. She stared at me blankly, then leaned her head close to the glass for a better look.
    She appeared to be in her fifties, with a sallow complexion and a deeply creased face. Her hair was too uniform a shade to be a natural brown. She wore it parted on the side with big puffy bangs across her lined forehead. Her eyes were the size and color of old pennies and her makeup looked like it needed renewing at this hour of the day. She wore a uniform I'd seen before, brown pants and a brown-and-yellow-checked tunic. I couldn't place the outfit offhand.
    "Yes?" she called through the glass.
    I raised my voice against the sound of the rain. "I'm looking for Billy. Is he back yet?"
    "He don't live here, hon, but he said he'd be by at eight o'clock. Who are you?"
    I picked a name at random. "Charlene. Are you his mother?"
    "Charlene who?"
    "A friend of his said I should look him up if I was ever in Santa Teresa. Is he at work?"
    She gave me an odd look, as if the notion of Billy working had never crossed her mind. "He's out checking the used car lots for an automobile."
    She had one of those faces that seemed tantalizingly familiar and it dawned on me, belatedly, that she was a checker at the supermarket where I shop now and then. We'd even chatted idly about the fact that I was a P.I. I eased back out of the porch light, hoping she hadn't recognized me at the same time I recognized her. I held the corner of the slicker up as though to shield my face from the wind.
    She seemed to pick up on the fact that something odd was going on. "What'd you want him for?"
    I ignored that, pretending I couldn't hear. "Why don't I come back when he gets home?" I hollered. "Just tell him Charlene stopped by and I'll catch up with him when I can."
    "Well, all right," she said reluctantly. I gave her a casual wave as I turned. I went down the porch steps and into the dark, aware that she was peering after me suspiciously. I must have disappeared from her field of vision then because she turned the porch light off.
    I got back in my car with one of those quick, involuntary shudders that racks you from head to toe. When I caught up with Billy, I might well admit who I was and what I wanted with him, but for the moment, I didn't want to tip my hand. I checked my watch and settled in, prepared to wait. Already, it was feeling like a long night.

Chapter 8
    Four hours passed. The rain stopped. It became apparent that Billy was not only late, but possibly not coming at all. Maybe he'd bought a car and hightailed it out of town, or maybe at some point he'd phoned his mother and decided to skip the visit when he heard about "Charlene." I finished all the coffee in the thermos, my brain fairly crackling from caffeine. If I smoked cigarettes, I could have gone through a pack. Instead, I listened to eight more installments of the news, the farm report, and an hour of Hispanic music. I pondered the possibility of learning the Spanish language by simply listening to these gut-wrenching tunes. I thought about Jonah and the husbands I'd known. Surely, if my heart broke again, it would sound just like this, though for all I knew, the lyrics were about cut worms and inguinal hernias, matters only made soulful through soaring harmonies. Altogether, I came perilously close to boring myself insensible with my own mental processes, so it was with real relief that I saw the car approach and pull into the curb in front of the house across the street. It looked like a 1967 Chevrolet, white, with a temporary registration sticker on the windshield. I couldn't tell much about the guy who got out, but I watched with interest as he took the porch steps in two bounds and rang the bell.
    Betty Christopher came to the door to let him in. The two of them disappeared. A moment later, shadows wavered against the kitchen light. I figured they'd sit
