“You can see where they rested the body. Halloa, Watson! what is this? There can be no doubt that it is a blood mark.” He was pointing to faint discolourations along the woodwork of the window. “Here it is on the stone of the stair also. The demonstration is complete. Let us stay here until a train stops. ”

We had not long to wait. The very next train roared from the tunnel as before, but slowed in the open, and then, with a creaking of brakes, pulled up immediately beneath us. It was not four feet from the window-ledge to the roof of the carriages. Holmes softly closed the window.

“So far we are justified,” said he. “What do you think of it, Watson?”

“A masterpiece. You have never risen to a greater height.”

“I cannot agree with you there. From the moment that I conceived the idea of the body being upon the roof, which surely was not a very abstruse one, all the rest was inevitable. If it were not for the grave interests involved the affair up to this point would be insignificant. Our difficulties are still before us. But perhaps we may find something here which may may help us.”

We had ascended the kitchen stair and entered the suite of rooms upon the first floor. One was a dining-room, severely furnished and containing nothing of interest. A second was a bedroom, which also drew blank. The remaining room appeared more promising, and my companion settled down to a systematic examination. It was littered with books and papers, and was evidently used as a study. Swiftly and methodically Holmes turned over the contents of drawer after drawer and cupboard after cupboard, but no gleam of success came to brighten his austere face. At the end of an hour he was no further than when he started.

“The cunning dog has covered his tracks,” said he. “He has left nothing to incriminate him. His dangerous correspondence has been destroyed or removed. This is our last chance.”

It was a small tin cash-box which stood upon the writing-desk. Holmes pried it open with his chisel. Several rolls of paper were within, covered with figures and calculations, without any note to show to what they referred. The recurring words “water pressure” and “pressure to the square inch” suggested some possible relation to a submarine. Holmes tossed them all impatiently aside. There only remained an envelope with some small newspaper slips inside it. He shook them out on the table, and at once I saw by his eager face that his hopes had been raised.

“What’s this, Watson? Eh? What’s this? Record of a series of messages in the advertisements of a paper. Daily Telegraph agony column by the print and paper. Right-hand top corner of a page. No dates — but messages arrange themselves. This must be the first:

“Hoped to hear sooner. Terms agreed to. Write fully to address given on card.

PIERROT.

“Next comes:

“Too complex for description. Must have full report. Stuff awaits you when goods delivered.

She spoke nervously. She could still see on Connie’s face the smoothness and the half–dream of passion, and she could feel the irritation against herself.

‘Quite!’ said Connie. And she could say no more.

The two women plodded on through the wet world, in silence, while great drops splashed like explosions in the wood. Ben they came to the park, Connie strode ahead, and Mrs Bolton panted a little. She was getting plumper.

‘How foolish of Clifford to make a fuss!’ said Connie at length, angrily, really speaking to herself.

‘Oh, you know what men are! They like working themselves up. But he’ll be all right as soon as he sees your Ladyship.’

Connie was very angry that Mrs Bolton knew her secret: for certainly she knew it.

Suddenly Constance stood still on the path.

‘It’s monstrous that I should have to be followed!’ she said, her eyes flashing.

‘Oh! your Ladyship, don’t say that! He’d certainly have sent the two men, and they’d have come straight to the hut. I didn’t know where it was, really.’

Connie flushed darker with rage, at the suggestion. Yet, while her passion was on her, she could not lie. She could not even pretend there was nothing between herself and the keeper. She looked at the other woman, who stood so sly, with her head dropped: yet somehow, in her femaleness, an ally.

‘Oh well!’ she said. ‘I fit is so it is so. I don’t mind!’

‘Why, you’re all right, my Lady! You’ve only been sheltering in the hut. It’s absolutely nothing.’

They went on to the house. Connie marched in to Clifford’s room, furious with him, furious with his pale, over–wrought fee and prominent eyes.

‘I must say, I don’t think you need send the servants after me,’ she burst out.

‘My God!’ he exploded. ‘Where have you been, woman, You’ve been gone hours, hours, and in a storm like this! What the hell do you go to that–bloody wood for? What have you been up to? It’s hours even since the rain stopped, hours! Do you know what time it is? You’re enough to drive anybody mad. Where have you been? What in the name of hell have you been doing?’

‘And what if I don’t choose to tell you?’ She pulled her hat from her head and shook her hair.

He lied at her with his eyes bulging, and yellow coming into the whites. It was very bad for him to get into these rages: Mrs Bolton had a weary time with him, for days after. Connie felt a sudden qualm.

But really!’ she said, milder. ‘Anyone would think I’d been I don’t know where! I just sat in the hut during all the storm, and made myself a little fire, and was happy.’

She spoke now easily. After all, why work him up any more!

He looked at her suspiciously.

And look at your hair!’ he said; ‘look at yourself!’

‘Yes!’ she replied calmly. ‘I ran out in the rain with no clothes on.’
