‘What are they?’ she asked.

‘Sort of petunia, I suppose,’ he answered. ‘I don’t really know them.’

‘They are quite strangers to me,’ she said.

They stood together in a false intimacy, a nervous contact. And he was in love with her.

She was aware of Mademoiselle standing near, like a little French beetle, observant and calculating. She moved away with Winifred, saying they would go to find Bismarck.

Gerald watched them go, looking all the while at the soft, full, still body of Gudrun, in its silky cashmere. How silky and rich and soft her body must be. An excess of appreciation came over his mind, she was the all–desirable, the all–beautiful. He wanted only to come to her, nothing more. He was only this, this being that should come to her, and be given to her.

At the same time he was finely and acutely aware of Mademoiselle’s neat, brittle finality of form. She was like some elegant beetle with thin ankles, perched on her high heels, her glossy black dress perfectly correct, her dark hair done high and admirably. How repulsive her completeness and her finality was! He loathed her.

Yet he did admire her. She was perfectly correct. And it did rather annoy him, that Gudrun came dressed in startling colours, like a macaw, when the family was in mourning. Like a macaw she was! He He watched the lingering way she took her feet from the ground. And her ankles were pale yellow, and her dress a deep blue. Yet it pleased him. It pleased him very much. He felt the challenge in her very attire–she challenged the whole world. And he smiled as to the note of a trumpet.

Gudrun and Winifred went through the house to the back, where were the stables and the out–buildings. Everywhere was still and deserted. Mr Crich had gone out for a short drive, the stableman had just led round Gerald’s horse. The two girls went to the hutch that stood in a corner, and looked at the great black–and–white rabbit.

‘Isn’t he beautiful! Oh, do look at him listening! Doesn’t he look silly!’ she laughed quickly, then added ‘Oh, do let’s do him listening, do let us, he listens with so much of himself;–don’t you darling Bismarck?’

‘Can we take him out?’ said Gudrun.

‘He’s very strong. He really is extremely strong.’ She looked at Gudrun, her head on one side, in odd calculating mistrust.

‘But we’ll try, shall we?’

‘Yes, if you like. But he’s a fearful kicker!’

They took the key to unlock the door. The rabbit exploded in a wild rush round the hutch.

‘He scratches most awfully sometimes,’ cried Winifred in excitement. ‘Oh do look at him, isn’t he wonderful!’ The rabbit tore round the hutch in a hurry. ‘Bismarck!’ cried the child, in rousing excitement. ‘How DREADFUL you are! You are beastly.’ Winifred looked up at Gudrun with some misgiving in her wild excitement. Gudrun smiled sardonically with her mouth. Winifred made a strange crooning noise of unaccountable excitement. ‘Now he’s still!’ she cried, seeing the rabbit settled down in a far corner of the hutch. ‘Shall we take him now?’ she whispered excitedly, mysteriously, looking up at Gudrun and edging very close. ‘Shall we get him now?–’ she chuckled wickedly to herself.

“This was the first point gained. I then walked slowly down the garden path, which happened to be composed of a clay soil, peculiarly suitable for taking impressions. No doubt it appeared to you to be a mere trampled line of slush, but to my trained eyes every mark upon its surface had a meaning. There is no branch of detective science which is so important and so much neglected as the art of tracing footsteps. Happily, I have always laid great stress upon it, and much practice has made it second nature to me. I saw the heavy footmarks of the constables, but I saw also the track of the two men who had first passed through the garden. It was easy to tell that they had been before the others, because in places their marks had been entirely obliterated by the others coming upon the top of them. In this way my second link was formed, which told me that the nocturnal visitors were two in number, one remarkable for his height (as I calculated from the length of his stride), and the other fashionably dressed, to judge from the small and elegant impression left by his boots.

“On entering the house this last inference was confirmed. My well-booted man lay before me. The tall one, then, had done the murder, if murder there was. There was no wound upon the dead man’s person, but the agitated expression upon his face assured me that he had foreseen his fate before it came upon him. Men who die from heart disease, or any sudden natural cause, never by any chance exhibit agitation upon their features. Having sniffed the dead man’s lips, I detected a slightly sour smell, and I came to the conclusion that he had had poison forced upon him. Again, I argued that it had been forced upon him from the hatred and fear expressed upon his face. By the method of exclusion, I had arrived at this result, for no other hypothesis would meet the facts. Do not imagine that it was a very unheard-of idea. The forcible administration of poison is by no means a new thing in criminal annals. The cases of Dolsky in Odessa, and of Leturier in Montpellier, will occur at once to any toxicologist.

“And now came the great question as to the reason why. Robbery had not been the object of the murder, for nothing was taken. Was it politics, then, or was it a woman? That was the question which confronted me. I was inclined from the first to the latter supposition. Political assassins are only too glad to do their work and to fly. This murder had, on the contrary, been done most deliberately, and the perpetrator had left his tracks all over the room, showing that he had been there all the time. It must have been a private wrong, and not a political one, which called for such a methodical revenge. When the inscription was discovered upon the wall, I was more inclined than ever to my opinion. The thing was too evidently a blind. When the ring was found, however, it settled the question. Clearly the murderer had used it to remind his victim of some dead or absent woman. It was at this point that I asked Gregson whether he had inquired in his telegram to Cleveland as to any particular point in Mr. Drebber’s former career. He answered, you remember, in the negative.
