My mind flew back to our first encounter at the Thirteen Drakes. Although I had seen his taxi pull up at the front door, and had heard Tully Stover shout at Mary that Mr. Pemberton had arrived early, I had not actually laid eyes on the man himself. That did not take place until Sunday, at the Folly.
Although there had been several odd things about Pemberton's sudden appearance at Buckshaw, I really hadn't had time to think about them.
In the first place, he hadn't arrived in Bishop's Lacey until hours after Horace Bonepenny had expired in my face. Or had he?
When I looked up and saw Pemberton standing at the edge of the lake, I had been taken by surprise. But why? Buckshaw was my home: I had been born and lived there every minute of my life. What was so surprising about a man standing at the edge of an artificial lake?
I could feel an answer to that question nibbling at the hook I'd lowered into my subconscious. Don't look straight at it, I thought, think of something else—or at least pretend to.
It had been raining that day, or had just begun to rain. I had looked up from where I was sitting on the steps of the little ruined temple and there he was, across the water on the south side of the lake: the southeast side, to be precise. Why on earth had he made his appearance from that direction?
That was a question to which I had known the answer for quite some time.
Bishop's Lacey lay to the northeast of Buckshaw. From the Mulford Gates, at the entrance to our avenue of chestnut trees, the road ran in easy twists and turns, more or less directly into the village. And yet Pemberton had appeared from the southeast, from the direction of Doddingsley, which lay about four miles across the fields. Why then, in the name of Old Stink, I had wondered, would he choose to come that way? The choices had seemed limited, and I had quickly jotted them down in my mental notebook:
If (as I suspected) Pemberton was the murderer of Horace Bonepenny, could he have been, as all murderers are said to be, drawn back to the scene of the crime? Had he perhaps left something behind? Something like the murder weapon? Had he returned to Buckshaw to retrieve it?
Because he had already been to Buckshaw the night before, he knew the way across the fields and wanted to avoid being seen. (See 1 above)
What if on Friday, the night of the murder, Pemberton, believing that Bonepenny was carrying the Ulster Avengers, had followed him from Bishop's Lacey to Buckshaw and murdered him there?
But hold on, Flave, I thought. Hold your horses. Don't go galloping off like that.
Why wouldn't Pemberton simply waylay his victim in one of those quiet hedgerows that border nearly every lane in this part of England?
The answer had come to me as if it were sculpted in red neon tubing in Piccadilly Circus: because he wanted Father to be blamed for the crime!
Bonepenny had to be killed at Buckshaw!
Of course! With Father a virtual recluse, it was unlikely to expect that he would ever happen to be away from home. Murders—at least those in which the murderer expected to escape justice—had to be planned in advance, and often in very great detail. It was obvious that a philatelic crime needed to be pinned on a philatelist. If Father was unlikely to come to the scene of the crime, the scene of the crime would have to come to Father.
And so it had.
Although I had first formulated this chain of events—or, at least, certain of its links—hours ago, it was only now, when I was at last forced to be alone with Flavia de Luce, that I was able to fit together all the pieces.
Flavia, I'm proud of you! Marie-Anne Paulze Lavoisier would be proud of you too.
Now then: Pemberton, of course, had followed Bonepenny as far as Doddingsley; perhaps even all the way from Stavanger. Father had seen them both at the London exhibition just weeks ago—proof positive that neither one was living abroad permanently.
They had probably planned this together, this blackmailing of Father. Just as they had planned the murder of Mr. Twining. But Pemberton had a plan of his own.
Once satisfied that Bonepenny was on his way to Bishop's Lacey (where else, indeed, would he be going?), Pemberton had got off the train at Doddingsley and registered himself at the Jolly Coachman. I knew that for a fact. Then, on the night of the murder, all he had to do was walk across the fields to Bishop's Lacey.
Here, he had waited until he saw Bonepenny leave the inn and set out on foot for Buckshaw. With Bonepenny out of the way and not suspecting that he was being followed, Pemberton had searched the room at the Thirteen Drakes, and its contents—including Bonepenny's luggage—and had found nothing. He had, of course, never thought, as I had, to slit open the shipping labels.
By now, he must have been furious.
Slipping away from the inn unseen (most likely by way of that steep back staircase), he had tracked his quarry on foot to Buckshaw, where they must have quarreled in our garden. How was it, I wondered, that I hadn't heard them?
