I had to assure them profusely that I would take no action to stop it.

Next, I turned to the mail sent to 26 Banbury Drive, Oxford.

In all, there had been forty-two different items in Mr. Horner's cardboard box, but most of them were junk circulars and free papers with no name or address. Six of them, however, were of particular interest to me. Three were addressed to Mr. R. Ward, a fourth to Mrs. Jane Philips, my mother, and the two others to a Mrs. Stella Beecher, all three persons supposedly resident at 26 Banbury Drive, Oxford.

Two of the letters to Roderick Ward had not been that informative, simply being tax circulars giving general notes of new tax bands. The third, however, was from Mr. Anthony Cigar of Rock Bank (Gibraltar) Ltd, formally confirming the immediate closure of the bank's investment fund and the imminent proceedings in the Gibraltar bankruptcy court. The letter was, in fact, a copy of one addressed to my mother and stepfather at Kauri House. It was dated July 7, 2009, and almost certainly did not arrive in Banbury Drive until after Roderick's fatal car accident of the night of July 12.

On the other hand, the letter to Mrs. Jane Philips, my mother, was much more recent. It was a computer-generated notice of an automatic penalty of one hundred pounds for the late filing of her tax return which had been due just ten days ago.

But it was the two letters to Mrs. Stella Beecher that were the real find.

One was from the Oxford Coroner's Office, informing her that the adjourned inquest into the death of her brother, Roderick Ward, was due to be reconvened on February 15-next Monday.

And the other was a handwritten note on lined paper that simply read, in capital letters: I DON'T KNOW WHETHER THIS WILL GET THERE IN TIME, BUT TELL HIM I HAVE THE STUFF HE WANTS.

I picked up the envelope in which it had arrived. It was a standard white envelope available from any high-street store. The address had also been handwritten in the same manner as the note. The postmark was slightly blurred, and it was difficult to tell where it had actually been posted. However, the date was clear to see. The letter had been mailed on Monday, July 13, the day after Roderick Ward supposedly died, the very day his body had been discovered.

I sat on my bed for quite a while, looking at the note and wondering if "in time" meant before the "accident" occurred and if "the stuff " had anything to do with my mother's tax papers.

I looked carefully at it once again. Now, I was no handwriting expert, but this message to Stella Beecher looked, to my eyes, to have been written in the same style, and to be on the same type of paper, as the blackmail note that I had found on my mother's desk.

On Thursday evening, at seven forty-five, I carried a bottle of fairly reasonable red wine around from Kauri House to the Hall in Lambourn for a kitchen supper with Isabella and her guests. I was looking forwards to a change in both venue and company.

As I had expected, the supper was not quite as casual as Isabella had made out. Far from being in jeans, she herself was wearing a tight black dress that showed off her alluring curves to their best advantage. I was pleased with myself that I had decided to put on a jacket and tie, but there again, I'd worn a jacket and tie for dinner in officers' messes for years, especially on a weekday. Dressing for dinner, even for a kitchen supper, was like a comfort blanket. For all its preoccupation with killing the enemy, the British Army was still very formal in its manners.

"Tom," she squealed, opening the front door wide and taking my offered bottle. "How lovely. Come and meet the others."

I followed her from the hallway towards the kitchen, and the noise. The room was already pretty full of guests. Isabella grabbed my arm and pulled me into the throng, where everyone seemed to be talking at once.

"Ewen," she shouted to a fair-haired man about forty years old. "Ewen," she shouted again, grabbing hold of his sleeve. "I want you to meet Tom. Tom, this is Ewen Yorke. Ewen, Tom."

We shook hands.

"Tom Forsyth," I said.

"Ah," he said in a dramatic manner, throwing an arm wide and nearly knocking over someone's glass behind him. "Jackson, we have a spy in our midst."

"A spy?" Isabella said.

"Yes," Ewen said. "A damn spy from Kauri Stables. Come to steal our secrets about Saturday."

"Ah," I said. "You must mean about Newark Hall in the Game Spirit." His mouth opened. "You've got no chance with Scientific running."

"There you are," he boomed. "What did I tell you? He's a bloody spy. Fetch the firing squad." He laughed heartily at his own joke, and we all joined in. Little did he know.

"Where is this spy?" said a tall man, pushing his way past people towards me.

"Tom," said Isabella. "This is my husband, Jackson Warren."

"Good to meet you," I said, shaking his offered hand and hoping he couldn't see the envy in my eyes, envy that he had managed to snare my beautiful Isabella.

Jackson Warren certainly didn't give the impression of someone suffering from prostate cancer. I knew that he was sixty-one years old because I'd looked him up on the Internet, but his lack of any gray hair seemed to belie the fact. Rather unkindly, I wondered if he dyed it, or perhaps just being married to a much younger woman had helped keep him youthful.

"So, are you spying on us, or on Ewen?" he asked jovially, with an infectious booming laugh.

"Both," I said jokily, but I had partially misjudged the moment.

"Not for the Sunday papers, I hope," he said, changing his mood instantly from amusement to disdain. "Though, I suppose, one more bastard won't make any difference." He laughed once more, but this time, the amusement didn't reach his eyes and there was an unsettling seriousness about his face.

"Come on, darling," said Isabella, sensing his unease. "Relax. Tom's not a spy. In fact, he's a hero."

I gave her a stern look as if to say, "No, please don't," but the message didn't get through.

"A hero?" said Ewen.

Isabella was about to reply when I cut her off sharply.

"Isabella exaggerates," I said quickly. "I'm in the army, that's all. And I've been in Afghanistan."

"Really," said an attractive woman in a low-cut dress who was standing next to Ewen. "Was it very hot?"

"No, not really," I said. "It's very hot in the summer, but it's damn cold in the winter, especially at night." Trust a Brit, I thought, to talk about the weather.

"Did you see any action?" Ewen asked.

"A fair bit," I said. "But I was only there for a couple of months this last time."

"So you've been before?" Ewen said.

"I've been in the army since I was seventeen," I said. "I've been most places."

"Were you in Iraq?" the woman asked with intensity.

"Yes. In Basra. And also in Bosnia and Kosovo. The modern army keeps you busy." I laughed.

"How exciting," she said.

"It can be," I agreed. "But only in short bursts. Mostly it's very boring." Time, I thought, to change the subject. "So, Ewen," I said, "how many horses do you train?"

"There you are," he said expansively. "I told you he was a spy."

We all laughed.

The attractive woman next to Ewen turned out to be his wife, Julie, and I found myself sitting next to her at supper at one of two large round tables set up in the extensive Lambourn Hall kitchen.

On the other side, on my left, was a Mrs. Toleron, a rather dull gray-haired woman who didn't stop telling me about how successful her "wonderful" husband had been in business. She had even introduced herself as Mrs. Martin Toleron, as if I would recognize her spouse's name.

"You must have heard of him," she exclaimed, amazed that I hadn't. "He was head of Toleron Plastics until we sold out a few months ago. It was all in the papers at the time, and on the television."
