I was getting ready to throw an impossibly heavy sandbag off the bluff the next morning when Michael came along walking Spike.
'What are you doing?' Michael said. 'Helping Dad help the sheriff with his investigation.'
'Ready!' Dad called up from the beach. I took a deep breath and then grappled with the sandbag.
'Here, let me help you with that,' Michael said, looking for somewhere to tie Spike's leash.
'No, no!' I said. 'That would spoil the test.'
'Test? What test? That thing must weigh a ton.'
'A hundred and five pounds, actually,' I puffed. 'Stand clear.' I wrestled the bag as close to the edge of the bluff as I dared, gave it a desperate heave over the side, and fell back panting. I heard the bag crashing through the brush on the way down. 'One more to go,' I said, as I collapsed onto the ground by the last sandbag.
'I assume this has something to do with the murder?' Michael said, sitting down on the grass beside me. 'Was that all she weighed, a hundred and five pounds?'
'Was that all? You try lugging one of these,' I said. 'Actually, a hundred and two, according to the medical examiner, but Dad decided to add three pounds for clothes. We're doing some testing for the sheriff.'
'Ready!' Dad called again.
'Testing what?' Michael asked. 'And why do you have to throw them?'
'If you want to throw some next, that would be fine with Dad. And great with me, I'm done in, and Rob's beat, too, and we both want to keep Dad from doing too much of the throwing. He's very fit but he's not invulnerable. But seeing how much strength it would have taken to have thrown her over is one of the things we're testing. I'm pretty damned strong for a woman, and it's about as much as I can do to drag them to the edge and shove them over. Here goes.'
I slung the bag over the side, but this bag didn't go as far and stuck in the bushes. 'Damn,' I said, and grabbed up the garden rake. I shoved at the bag until it finally toppled over and went crashing down the side.
'All gone!' I shouted over the side.
'You said how much strength it would take was one of the things you were finding out,' Michael said. 'What else is this intended to discover?'
'All sorts of grisly things. Could the underbrush or the water break Mrs. Grover's fall enough to result in the relatively minimal injuries she sustained?'
'And could it?'
'Not bloody likely. And how much noise a hundred-and-five-pound object makes when landing, on sand and in the water, and how far away you can hear the noise, and the answers are less than you think, and not with the riding lawn mower running.'
'Was it running?'
'Much of the time, yes. And whether there's any possibility she could merely have tripped and fallen over.'
'Somehow I doubt that.'
'Yes, it's so unlikely that we can pretty much discard it, no matter where you try it. Similarly, it's highly unlikely that anyone could have shoved her over. It very much looks as if the only way she could have gone over under her own steam would be if she took a running broad jump at the edge. And even then she'd have to be pretty athletic for a fifty-five-year-old.'
'Aren't you afraid of destroying evidence?' Michael asked.
'They've been all over this stretch of the cliff, and found nothing,' I replied. 'No sign of one-hundred-five- pound weights having crashed through the brush, no scraps of clothing, no stray objects. At least none that could reasonably be assumed to have fallen off Mrs. Grover. That's another thing Dad wants to prove, how unlikely it would be for Mrs. Grover to have fallen over the cliff without leaving any traces on her or the cliff.'
'How do you know this is where she went over?' Michael asked. 'I thought she was found a little further downstream than this.'
'We're trying it at all the likely places along the bluff. All upstream from where she was found, of course. Next he's planning to do some tide and current tests to see if it would be plausible for a dead body dumped in the river to wash up where hers was found.'
'Using what?' Michael asked, dubiously. 'I mean, sandbags obviously won't cut it.'
'Rob and I are trying to convince him just to use a whole bunch of floats instead of actual dead bodies. Of animals, of course,' I added, hastily, seeing the look on Michael's face. 'He's been talking to meatpacking houses.'
'Lovely,' Michael said, just as Dad and Rob came puffing up the ladder. I hoped Michael wouldn't laugh when he saw that Rob was carrying a camcorder.
'Michael!' Dad said, enthusiastically, as he flung himself down by us, mopping his face with his handkerchief. 'Glad to see you; we could certainly use your help!'
'So Meg was telling me.'
'Oh, Meg, how about some lemonade or iced tea?' Dad said. 'Or a beer. Anything cold.'
'Meg's been playing stevedore,' Michael said. 'How about if I fetch the refreshments?'
'Good idea.' Dad approved. 'And when you get back I'll tell you what you can do.'
I don't know whether Rob's videotapes and the meticulous notes Dad had been taking impressed Michael with the value of our efforts or whether he allowed himself to be recruited for the entertainment value. There are people in town who gladly help Dad out with his most hare-brained projects and then dine out on the stories for months afterwards. Or maybe it was the camcorder. Michael was an actor; perhaps the ham in him couldn't resist the chance to be in front of a camera. Whatever the reason, for the next couple of hours Michael joined in energetically as we shoveled sand into the bags, dragged them up from the beach with a winch the next-door neighbors had installed to haul their boat up to their driveway, weighed them, and then heaved them down again while Dad scribbled more pages of notes.
Jake came over to watch briefly at one point, and Dad tried to enlist his help, but as I pointed out, it was his sister-in-law's demise we were trying to reenact, so he could hardly be blamed for feeling a little squeamish about the prospect.
It's always entertaining to watch a couple of men who've been bit by the macho competitive bug and are earnestly trying to outdo each other at something relatively pointless, like heaving giant sandbags over cliffs. Once he got the hang of it, Michael proved to be slightly better at sandbag-heaving than Rob, and so it was Michael who got to demonstrate for the sheriff when he came out that evening.
The sheriff couldn't help smiling at Dad's enthusiasm, but I could tell Dad was beginning to convince him.
'So you see, I think we've pretty clearly established that Mrs. Grover did not fall from the cliff accidentally,' Dad pontificated over lemonade on the porch after our demonstration. 'There was nothing on the cliffside to indicate the passage of a falling object the size of a body.'
'There is now,' Michael said.
'Don't worry, young man,' the sheriff said. 'We searched it pretty thoroughly for a couple days. Nothing to be found.'
'No traces of leaves or dirt on her body,' Dad went on, relentlessly. 'And, as you can see from the effect on the sandbags, it is highly unlikely that she could have fallen, either postmortem or antemortem, without significantly greater injury. I postulate that she was taken to the beach, probably by the Donleavys' path, possibly by the neighbors' backyard staircase.'
'Or by boat,' Rob suggested.
'Yes, it's possible,' Dad conceded, frowning. 'Of course it's unlikely. Unless someone risked discovery by bringing her by boat from quite a distance. They'd have been just as noticeable carrying her down to a boat anywhere near here as they would simply carrying her down to the beach to dump her body. But you're right; we can't overlook the possibility of a boat.'
He looked very depressed. Doubtless the possibility of a boat either contradicted his pet theory or, more likely, emphasized how difficult it would be to catch the culprit. I felt sorry for him.
