There were times when I surprised even myself.
"And even if she hadn't," I added, "she'd certainly attended some of the shows he put on round the countryside. She'd have paid particular attention to the electrical rigging. Since Rupert manufactured all of his own lighting equipment, I can hardly believe that he wouldn't have taken the opportunity to show off the details to a fellow electrician. He was rather vain about his skills, you know.
"I expect Grace took the keys from the vicarage and walked straightaway through the churchyard, to the parish hall. The afternoon performance was over by that time; the audience had gone, and so had Rupert. There was little chance of her being seen. Even if she had been spotted, no one would have paid her the slightest attention, would they? After all, she was just the egg lady. Besides, she and her husband are parishioners of St. Tancred's, so no one would have given her a second look.
"She went into the hall, and using the corridor to the left, and locking the door behind her, went up the two short flights of steps to the stage.
"She climbed up onto the bridge of the puppet stage, and scraped away the insulation from the wiring, using the bicycle clip as a kind of spoke-shave. Then she slipped the clip over the wooden framework of the stage, touching the bared electrical wire on the one side and the metal rod that released Galligantus on the other. Bob's your uncle! That's all there was to it. If you've had a close look at the clip, you've likely already found a small abrasion mark on the inside center — and perhaps slight traces of copper."
"S'truth!" Sergeant Woolmer let slip, and Inspector Hewitt shot him a look.
"Unlike most of the other suspects — except Dieter, of course, who built wireless sets as a boy in Germany — Grace Ingleby had the necessary electrical training. Before the war, before marrying Gordon, she worked in a factory installing radio sets in Spitfires. I've been told that her IQ is nearly equal in number to the Psalms."
"Dammit!" Inspector Hewitt shouted, leaping to his feet. "Sorry, Vicar. But why haven't we found these things out, Sergeant?"
He glared from one of his men to the other, including both in his exasperation.
"With respect, sir," Sergeant Woolmer ventured, "it could be because we're not Miss de Luce."
It was a bold thing to say, and a rash one. If what I'd seen in the pictures at the cinema were true, it was the sort of remark that could result in the sergeant becoming a road-mender before sunset.
After a nerve-racking silence, the Inspector said, "You're right, of course, Sergeant. We don't have the same entree to the homes and hearths of Bishop's Lacey, do we? It's an area in which we could do better. Make a note of it."
No wonder his subordinates adored him!
"Yes, sir," said Sergeant Graves, scribbling something in his notebook.
"Then," I went on, "having set the trap, Grace went out by the hallway door at the right of the stage, and she locked that one, too — probably to keep anyone from going backstage and discovering what she had done. Not that anyone would, of course, but I expect she was under a great deal of stress. She's been planning to take her revenge on Rupert for a long time. It wasn't until she spotted the vicar's trouser clip on the floor that she saw exactly how it could be done. As I've said, she's a very intelligent woman."
"But," Inspector Hewitt said, "if both doors were locked, how did Porson get up onto the stage for the performance? He couldn't have locked himself in because he didn't have the key."
"He used that little staircase in front of the stage," I said. "It's not as steep as the two in the side halls, and it's only a single flight. Narrow stairs were difficult for Rupert because of his leg brace, and he took the shortest route. I noticed that about him last Thursday when he was checking the hall's acoustics."
"Quite an ingenious theory," Inspector Hewitt remarked. "But it doesn't explain everything. How, for instance, would the alleged murderer know that such a gimcrack bit of tin would result in Porson's death?"
"Because Rupert always leaned on a rail of iron piping as he operated the puppets. With all the lighting equipment that was hung backstage, the railing had to be grounded through the mains. The instant Rupert touched the live Galligantus lever, his lower body pressed tight against the rail as it was, with his right leg clamped in an iron brace, the current would have shot straight up his arm and through — "
"His heart," said the Inspector. "Yes, I see."
"Rather like Saint Lawrence," I said, "who, as you know, was done to death on a grill."
"Thank you, Flavia," Inspector Hewitt said. "I think you've made your point."
"Yes," I said, rather smugly, "so do I. Will that be all, then?"
Sergeant Graves was grinning away over his notebook like Scrooge over his ledgers.
Inspector Hewitt wrinkled his brow in a look that I had seen before: a look of exasperated curiosity held in firm check by years of training and a strong sense of duty.
"I think so, yes — except for one or two small points, perhaps."
I gave him that beaming, superior smile: all teeth and thin lips. I almost hated myself for doing it.
"Yes, Inspector?"
He walked to the window, his hands clasped behind his back, as I had seen him do before on several occasions. At last he turned: "Perhaps I'm a bit of a dim bulb," he said.
If he was waiting for me to contradict him, he'd be waiting until the cows came home in purple pajamas.
"Your observations on the death of Rupert Porson have been most illuminating. But try as I may, I have failed utterly to follow your reasoning in the death of Robin Ingleby.
"The boots, yes ... perhaps. It's a possibility, I admit, but far from a certainty. Slender evidence when it comes to court. If the case is reopened, that is. But we shall require far more than a pair of child's boots if we are to prevail again upon their Lordships."
His tone was almost pleading. I had already decided that there were certain observations that would remain forever locked away in my brain: choice nuggets of deduction that I would keep for my own private delectation. After all, the Inspector had far more resources at his disposal than I did.
But then I thought of his beautiful wife, Antigone. Whatever would she think of me if she found that I had thwarted him? One thing was certain: It would scotch any idea I might have had of sipping tea in the garden of their tastefully decorated maisonette.
"Very well," I said reluctantly. "There are a few more points. The first is this: When Dieter went running back to the farmyard, having just discovered Robin's dead body hanging in Gibbet Wood, the windows of the house were empty. No one was awaiting his arrival, as might have been expected. Surely the mother of a missing child would be frantic, waiting for the slightest scrap of news? But Grace Ingleby wasn't keeping watch at the windows. And why not? The reason is a simple one: She already knew that Robin was dead."
Somewhere behind me, the vicar gasped.
"I see." Inspector Hewitt nodded. "An ingenious theory ... most ingenious. But still hardly enough to build a case upon."
"Granted," I agreed, "but there's more."
I looked from one of them to another: the vicar, Inspector Hewitt, and Sergeant Graves, their eager faces thrust forward, hanging upon my every word. Even the hulking Sergeant Woolmer slowed his polishing of the intricate lens.
"Robin Ingleby's hair was always a haystack," I told them. "'Tousled' is perhaps the proper word. You can see it in his photos. And yet when he was found hanging from the timbers of the old gallows, his hair was as neatly combed as if he'd just climbed down from the barber's chair. Meg captured it perfectly in her drawing. See?"
There was an intake of breath as everyone huddled over the page from my notebook.
