Miss Marple paused and murmured to herself:

‘I must just count this row. The decreasing is a little awkward. One, two, three, four, five, and then three purl; that is right. Now, what was I saying? Oh, yes, about poor Mabel.

‘Mabel was my niece. A nice girl, really a very nice girl, but just a trifle what one might call silly. Rather fond of being melodramatic and of saying a great deal more than she meant whenever she was upset. She married a Mr Denman when she was twenty-two, and I am afraid it was not a very happy marriage. I had hoped very much that the attachment would not come to anything, for Mr Denman was a man of very violent temper—not the kind of man who would be patient with Mabel’s foibles—and I also learned that there was insanity in his family. However, girls were just as obstinate then as they are now, and as they always will be. And Mabel married him.

‘I didn’t see very much of her after her marriage. She came to stay with me once or twice, and they asked me there several times, but, as a matter of fact, I am not very fond of staying in other people’s houses, and I always managed to make some excuse. They had been married ten years when Mr Denman died suddenly. There were no children, and he left all his money to Mabel. I wrote, of course, and offered to come to Mabel if she wanted me; but she wrote back a very sensible letter, and I gathered that she was not altogether overwhelmed by grief. I thought that was only natural, because I knew they had not been getting on together for some time. It was not until about three months afterwards that I got a most hysterical letter from Mabel, begging me to come to her, and saying that things were going from bad to worse, and she couldn’t stand it much longer.

‘So, of course,’ continued Miss Marple, ‘I put Clara on board wages and sent the plate and the King Charles tankard to the bank, and I went off at once. I found Mabel in a very nervous state. The house, Myrtle Dene, was a fairly large one, very comfortably furnished. There was a cook and a house-parlourmaid as well as a nurse-attendant to look after old Mr Denman, Mabel’s husband’s father, who was what is called “not quite right in the head”. Quite peaceful and well behaved, but distinctly odd at times. As I say, there was insanity in the family.

‘I was really shocked to see the change in Mabel. She was a mass of nerves, twitching all over, yet I had the greatest difficulty in making her tell me what the trouble was. I got at it, as one always does get at these things, indirectly. I asked her about some friends of hers she was always mentioning in her letters, the Gallaghers. She said, to my surprise, that she hardly ever saw them nowadays. Other friends whom I mentioned elicited the same remark. I spoke to her then of the folly of shutting herself up and brooding, and especially of the silliness of cutting herself adrift from her friends. Then she came bursting out with the truth.
