A is for Alibi

I guessed was a caretaker's quarters above. The lawns were well tended and the house, while it had an unoccupied look, didn't seem neglected. I parked my car on the portion of the drive that circled back on itself to permit easy exit. In spite of the red-tiled roof, the house looked more French than Spanish: windows without cornices, the front door flush with the drive.
    I got out of my car and walked around to the right, my footsteps making no sound on the pale rosy bricks. In the rear, I could see the outline of a swimming pool and for the first time, I felt something chill and out of place. The pool had been filled to the brim with dirt and trash. An aluminum lawn chair was half-sunk in the sod, weeds growing through the rungs. The diving board extended now over an irregular surface of grass clippings and dead leaves, as though the water had thickened and congealed. A set of steps with handholds disappeared into the depths and the surrounding concrete apron was riddled with dark splotches.
    I found myself approaching with uneasiness and I was startled out of my concentration by the sound of malicious hissing. Waddling toward me with remarkable speed were two huge white geese, their heads thrust forward, mouths open like snakes with their tongues protruding, emitting a terrifying sound. I gave a low involuntary cry and began to backtrack toward my car, afraid to take my eyes off them. They covered the ground between us at a pace that forced me into a run. I barely reached my car before they caught up with me. I wrenched the door open and slammed it again with a panic I hadn't felt in years. I locked both doors, half expecting the viperous birds to batter at my windows until they gave way. For a moment they balanced, half lifted, wings flapping, black eyes bright with ill-will, their hissing faces even with mine. And then they lost interest and waddled off, honking and hissing, pecking savagely at the grass. Until that moment, it had never even occurred to me to include crazed geese among my fears, but they had suddenly shot straight to the top of the list along with worms and water bugs.
    Nikki's car pulled in behind mine. She got out with perfect composure and approached as I rolled my window down. The two geese appeared again around the comer of the house, making their flat-footed beeline for the flesh of her calves. She gave them an idle glance and then laughed. Both raised up again, short wings flopping ineffectually, their manner suddenly benign. Nikki had a bread bag in her hand and she tossed them some crumbs.
    "What the hell are those things?" I eased out of the car cautiously but neither paid the slightest attention to me.
    "That's Hansel and Gretel," she said amicably "They're Embden geese."
    "The geese part I could tell. What happened? Did somebody train them to kill?"
    "It keeps little kids off the property," she said. "Come on in. " She inserted a key in the lock and the front door swung open. Nikki stooped to pick up some junk mail that had been pushed through the slot. "The mailman gives them saltines," she said as an afterthought. "They'll eat anything."
    "Who else had keys to this place?" I asked. I noticed an alarm-system panel, which was apparently turned off.
    She shrugged. "Laurence and me. Greg and Diane. I can't think of anyone else."
    "Gardener? Maid?"
    "Both have keys now but I don't think they did at the time. We did have a housekeeper. Mrs. Voss. She probably had one."
    "Did you have a security system then?"
    "We do now but that's only been in the last four years. I should have sold the place years ago but I didn't want to make decisions like that when I was in prison.
    "It must be worth a lot."
    "Oh sure. Real-estate values have tripled and we paid seven hundred and fifty thousand at the time. He picked it out. Put it in my name for business reasons, but it never did appeal to me much."
    "Who did the decorating?" I asked.
    Nikki smiled sheepishly. "I did. I don't think Laurence knew any better, but I took a subtle revenge. He insisted that we buy the place so I left all the color out."
    The rooms were large, ceilings high, and plenty of light came in. The floors were dark-stained tongue and groove. The layout was very conventional: living room to the right, dining room to the left, with the kitchen behind. There was a sitting room beyond the living room and a long glassed-in porch along that side, running the length of the house. There was a curious air to the house, which I assumed was
