At once I recognized the sound I had heard. It was this same table lid being shut down gently and carefully. I repeated the action once or twice for my own satisfaction.

Then I lifted the lid to scrutinize the contents more closely.

I was still bending over the open silver table when Flora Ackroyd came into the room.

Quite a lot of people do not like Flora Ackroyd, but nobody can help admiring her. And to her friends she can be very charming. The first thing that strikes you about her is her extraordinary fairness. She has the real Scandinavian pale gold hair. Her eyes are blue - blue as the waters of a Norwegian fiord, and her skin is cream and roses. She has square, boyish shoulders and slight hips. And to a jaded medical man it is very refreshing to come across such perfect health.

A simple straightforward English girl - I may be oldfashioned, but I think the genuine article takes a lot of beating.

Flora joined me by the silver table, and expressed heretical doubts as to King Charles I ever having worn the baby shoe.

'And anyway,' continued Miss Flora, 'all this making a fuss about things because someone wore or used them seems to me all nonsense. They're not wearing or using them now.

That pen that George Eliot wrote The Mill on the Floss with - that sort of thing - well, it's only just a pen after all. If you're really keen on George Eliot, why not get The Mill on the Floss in a cheap edition and read it.' 'I suppose you never read such old out-of-date stuff. Miss Flora?' 'You're wrong, Dr Sheppard. I love The Mill on the Floss: I was rather pleased to hear it. The things young women read nowadays and profess to enjoy positively frighten me.

'You haven't congratulated me yet, Dr Sheppard,' said Flora. 'Haven't you heard?' She held out her left hand. On the third finger of it was an exquisitely set single pearl.

'I'm going to marry Ralph, you know,' she went on.

'Uncle is very pleased. It keeps me in the family, you see.' I took both her hands in mine.

'My dear,' I said, 'I hope you'll be very happy.' 'We've been engaged for about a month,' continued Flora in her cool voice, 'but it was only announced yesterday.

Uncle is going to do up Cross-stones, and give it to us to live in, and we're going to pretend to farm. Really, we shall hunt all the winter, town for the season, and then go yachting. I love the sea. And, of course, I shall take a great interest in the parish affairs, and attend all the Mothers' Meetings.' Just then Mrs Ackroyd rustled in, full of apologies for being late.

I am sorry to say I detest Mrs Ackroyd. She is all chains and teeth and bones. A most unpleasant woman. She has small pale flinty blue eyes, and however gushing her words may be, those eyes others always remain coldly speculative.

I went across to her, leaving Flora by the window. She gave me a handful of assorted knuckles and rings to squeeze, and began talking volubly.

Had I heard about Flora's engagement? So suitable in every way. The dear young things had fallen in love at first sight. Such a perfect pair, he so dark and she so fair.

'I can't tell you, my dear Dr Sheppard, the relief to a mother's heart.' Mrs Ackroyd sighed - a tribute to her mother's heart, whilst her eyes remained shrewdly observant of me.

'I was wondering. You are such an old friend of dear Roger's. We know how much he trusts to your judgment.

So difficult for me - in my position as poor Cecil's widow.

But there are so many tiresome things - settlements, you know - all that. I fully believe that Roger intends to make settlements upon dear Flora, but, as you know, he is just a leetle peculiar about money. Very usual, I've heard, amongst men who are captains of industry. I wondered, you know, if you could just sound him on the subject?

Flora is so fond of you. We feel you are quite an old friend, although we have only really known you just over two years.' Mrs Ackroyd's eloquence was cut short as the drawing-room door opened once more. I was pleased at the interruption. I hate interfering in other people's affairs, and I had not the least intention of tackling Ackroyd on the subject of Flora's settlements. In another moment I should have been forced to tell Mrs Ackroyd as much.

'You know Major Blunt, don't you, doctor?' 'Yes, indeed,' I said.

A lot of people know Hector Blunt - at least by repute.

He has shot more wild animals in unlikely places than any man living, I suppose. When you mention him, people say: 'Blunt - you don't mean the big game man, do you?' His friendship with Ackroyd has always puzzled me a little. The two men are so totally dissimilar. Hector Blunt is perhaps five years Ackroyd's junior. They made friends early in life, and though their ways have diverged, the friendship still holds. About once in two years Blunt spends a fortnight at Fernly, and an immense animal's head, with an amazing number of horns which fixes you with a glazed stare as soon as you come inside the front door, is a permanent reminder of the friendship.

Blunt had entered the room now with his own peculiar, deliberate, yet soft-footed tread. He is a man of medium height, sturdily and rather stockily built. His face is almost mahogany coloured, and is peculiarly expressionless. He has grey eyes that give the impression of always watching something that is happening very far away. He talks little, and what he does say is said jerkily, as though the words were forced out of him unwillingly.

He said now: 'How are you, Sheppard?' in his usual abrupt fashion, and then stood squarely in front of the fireplace looking over our heads as though he saw something very interesting happening in Timbuctoo.

'Major Blunt,' said Flora, 'I wish you'd tell me about these African things. I'm sure you know what they all are.' I have heard Hector Blunt described as a woman hater, but I noticed that he joined Flora at the silver table with what might be described as alacrity. They bent over it together.

I was afraid Mrs Ackroyd would begin talking about settlements again, so I made a few hurried remarks about the new sweet pea. I knew there was a new sweet pea because the Daily Mail had told me so that morning. Mrs Ackroyd knows nothing about horticulture, but she is the kind of woman who likes to appear well-informed about the topics of the day, and she, too, reads the Daily Mail. We were able to converse quite intelligently until Ackroyd and his secretary joined us, and immediately afterwards Parker announced dinner.

My place at table was between Mrs Ackroyd and Flora.

Blunt was on Mrs Ackroyd's other side, and Geoffrey Raymond next to him.

Dinner was not a cheerful affair. Ackroyd was visibly preoccupied. He looked wretched, and ate next to nothing.

Mrs Ackroyd, Raymond, and I kept the conversation going.

Flora seemed affected by her uncle's depression, and Blunt relapsed into his usual taciturnity.

Immediately after dinner Ackroyd slipped his arm through mine and led me off to his study.

'Once we've had coffee, we shan't be disturbed again,' he explained. 'I told Raymond to see to it that we shouldn't be interrupted.' I studied him quietly without appearing to do so. He was clearly under the influence of some strong excitement. For a minute or two he paced up and down the room, then, as Parker entered with the coffee tray, he sank into an armchair in front of the fire.

The study was a comfortable apartment. Bookshelves lined one wall of it. The chairs were big and covered in dark blue leather. A large desk stood by the window and was covered with papers neatly docketed and filed. On a round table were various magazines and sporting papers.

'I've had a return of that pain after food lately,' remarked Ackroyd calmly, as he helped himself to coffee. 'You must give me some more of those tablets of yours.' It struck me that he was anxious to convey the impression that our conference was a medical one. I played up accordingly.
