There had been a great deal in the papers about the case which was called that of the Satanic Bride-groom. It was revealed that Hans Dowling was the son of a German mother and an English father; he had murdered two women. There was one before Lydia. Evidently it was a method of amassing wealth, for each of the murdered women had left money to him. His big killing was to be that of Fiona and her sister, through which he would get not only Fiona's fortune but that of her sister-which would pass to Fiona on Eugenie's death. It was the prospect of getting Eugenie's money as well as Fiona's which had kept Fiona alive. But for that she would have been despatched long ago.

Jason was my main preoccupation. Together we concentrated on getting him well. There were hours of exercising in which I helped; I was with him all through the days and we often engaged in those stimulating verbal battles which had been a feature of our relationship.

I was happier than I had ever been, once I knew that he was going to recover; and I often marvelled that so much happiness could come out of so much that was evil.

Daisy was grieved that I had not returned to school and that a little of the glory of Schaffenbrucken influence was removed from the school's prospectus; but she made it clear to parents that the young lady who had brought in the Schaffenbrucken influence was to become Lady Verringer, wife of the largest landowner in Devon. And I think she took some comfort from that.

Elsa was extradited and stood on trial in Austria. She had not actually killed, though she was accused of attempted murder and of complicity in murder. She confessed ail, which helped Fiona to accept the truth, and she was given a long prison sentence.

There must have been a great deal of talk in Colby and I could imagine what took place in those across-the-counter-parleys in the post office. Daisy wrote to me, most gratified, because no parents had seen fit to remove their daughters.

So we came home and were married in Colby church and the bells rang out on a very different note from that which had heralded my arrival.

Elsa turned out to be an exemplary prisoner and was eventually allowed privileges which enabled her to write a book about her life. It was very revealing.

She explained how she and her family had lived in poverty in the village of Croston in Suffolk. Their mother was thrifty; their father a drunken spendthrift. Before the fire he had worked for the squire, Edward Compton, and after the manor had been burned down he had worked only intermittently and eventually had drunk himself to death. At home the children had spoken German and at the village school English, so they were proficient in both languages. Elsa and her brother Hans were very close; they used to play together in the burned-out ruins and imagine that they owned such a mansion and lived there in splendour. Hans vowed that when he grew up he would find a way to own such a place and he and Elsa should live there together. It was the constant dream through the hard years. of poverty. Hans had become resentful of the rich. He used to go to the cemetery and look at the grave of Edward Compton. "You were burned to death," he would say. "Serve you right. You had everything. We have nothing. But one day I shall have everything I want ... Elsa and I together." They used to go into the church and stand before the plaques and monuments to the Compton family ... It was a vow. He told Elsa that it was a battle between such as they were and the rich. If the rich had to die to give them what they wanted, then die they must.

Elsa remembered the night she had gone with Hans to the ruins and he had looked at the moon and made a very solemn vow. It was the full moon ... the Hunter's Moon. He had said, "I am the hunter. I am hunting for that which I intend to have and when I have it, dear sister, I shall share it with you." Then he had gone into the church and there solemnly announced his intentions. It was a saying between them: "Remember the night of the Hunter's Moon."

Elsa had been pledged to help him. She had been frightened alter the first killing, which had been in Norway, but it had been carried out without a hitch. The marriage, an accident in the mountains, a grieving bridegroom who collected the wife's money and passed on. The first had brought small rewards and he had decided to look higher. Then he had heard of Schaffenbrucken-one of the most exclusive and expensive schools in Switzerland. All the young ladies there would be in their mid teens ... marriageable. And they devised their plan.

It was interesting to read about it, and something of Elsa's character came through in the book. She was fond of people; she liked gaiety and laughter; it was incredible that such a person could light heartedly contemplate murder.

She made it clear that they had both made damning mistakes. Her brother had made his when he had not found out enough about my expectations and had in a moment of thoughtlessness given me the name of Edward Compton. He had an almost mystic belief that he was going to succeed in my case because we had met at the time of the Hunter's Moon. It seemed to him a significant time; and that had made him over-confident and so ... careless. She had made her mistake in staying at the school when she discovered that by an odd quirk of Tate I was there.

"It was one of fate's mischievous tricks," she wrote, "that we should have chosen a school in which one of our intended victims was working."

She and her brother used to pick the wild flowers which grew among the ruins of Compton Manor. They read of the properties of these plants both healing and otherwise. They discovered that many of those which people regarded as ordinary flowers could produce deadly poisons. They had embarked on a career of murder and they might need poison. They learned that foxglove contained digitoxin and, although it could be used medicinally, in large doses it could be fatal; the leaves and seeds of the yew contained a deadly toxin; the various fungi growing in woods could produce death. Elsa became expert and distilled the juices, and tried them on animals to test their effectiveness.

"Strangely enough," she wrote, "I liked Eugenie. She was one of my favourites among the girls, but when I had to get rid of her I didn't think of her as Eugenie. She was just an object who was stopping our getting the mansion we had dreamed about. Hans said he felt the same. He didn't dislike his victims. He was quite fond of them and even when he committed the act of killing he did it in a coldblooded aloof sort of way. There was no malice in him towards his victim; it was just part of his grand scheme that they should be removed."

It was a revealing document. It explained so much about which we had hitherto wondered. I could not, of course, understand Elsa. But then who does fully understand another human being?

Two years after my flight to Austria, Teresa married John Markham. She was then nineteen. She was married from Moldenbury for her parents were still in Rhodesia. She adored him and was supremely happy. I was sure it was a perfect marriage, for if John had ever thought of marriage with me - which I believe he had - and if he had been disappointed when I married Jason, he would accept what had happened and find happiness elsewhere. He was the sort of man who would be successful in anything that came his way and that would include his emotional life. He would be the same good-humoured, loving and tender husband to Teresa as he would have been to me. He was just what Teresa needed.

But all this was some time ahead.

For the time there was my own marriage and the joyous realization that Jason and I were the sort of people who could never have been really happy with anyone but each other.

How we laughed at the excitement in the town. The marriage had completely superseded the great murder mystery which had touched the school.

Memories were revived.

"What about his first wife? Does that schoolmistress know? And then there was that Mrs. Martindale. He's a one, he is. Well, didn't they say the Verringers had the devil in them?"

We laughed at the gossip. I was rather glad of it. It showed me and Jason without a doubt that I was ready to accept anything for his sake. I wanted him to know that, and to go on remembering it.

It was round about Christmas time, two years after our marriage. We were the proud parents of a son by that time.

Jason was very anxious that we should go to London.

"You can shop," he said. "There must be lots of things you want."

I was not averse. I had an excellent nanny for young Jason and I had no qualms about leaving him.

When we arrived at the London house, Jason said he wanted to take me to the theatre, for there was a play he particularly wanted to see. I was amused when we arrived to see that it was East Lynne and when I glanced at the programme the names seemed to rush up at me. "Marcia and Jack Martindale. Together again in their original roles."

The curtain went up and there she was. The Lady Isabel.

I don't know how I sat through the play, and afterwards we went backstage to see her and Jack.

"Miraculously risen from his watery grave," I said.

"Oh, he's a survivor," replied Marcia dramatically.

We told her about the speculation in Colby about her departure, which she thought was highly diverting. So did the hardy Jack.

"I tell you what we'll do," she said. "We'll pay a call this Christmas. Won't that be fun, Jack? We'll ride through the streets and show all those dear old gossips that we are still on Earth."

They did. Marcia insisted on showing Rooks' Rest to Jack and going to visit her dear little baby on the moor.

We were delighted to see their departure and we laughed a great deal about them.

"They'll act their way through life," said Jason. "I'm wondering what Mrs. Baddicombe will have to talk about now."

"I'm rather sorry in a way," he said. "I always used to say to myself. She must love me a great deal to marry me when there's this cloud of suspicion hanging over me."

"Well, now you can tell yourself that there was never any reason to doubt it."

"No. And yet it never ceases to amaze me. There's a great deal you don't know about me."

"I'm glad," I said. "I shall look forward to improving my education."
